WOW,
very nice, I am waiting on a CMMG, and am excited for a BCM, and this is just great! Glad to see more LW barrels on the market, do we have a price or place to buy these? I have a feeling that it is easier to get a Centurion from retailers than direct, or atleast it is damn hard to get a MK12 from them.

grinch

12-03-09, 01:09

Wow, this would make a very interesting "recce-ish" build. :)

Thanks for the heads-up, SMGLee, I have been looking forward to doing a lightweight middy upper.

Thanks for the additional info, Monty, and stay safe!

12-05-09, 22:43

Any 14.5 inch barrels in the works ? I'd like to keep it as short as possible without all the NFA paper work. Carbine length hopefully.

grinch

12-06-09, 01:14

I have them in stock right now for sale and should be stocked up for awhile.

it uses .750 gas blocks or FSP.

I'm not sure if I will ever do a 14.5in only time will tell.

I chose to do a 12.5in over the 10.5in since it has significant advantages but once again I would not rule it out.

If I do a 20in it will probably be a mid weight or a little heavier and will be set up as a precision barrel.

Thanks

Monty,

Do you know if you can attach a KAC QDSS NT4 on a 12.5" upper that is using either a DD M4A1 RIS ll or a DD AR15 Lite Rail 12.0? I also wanted to know if you can either do a shaved FSB or a pinned gas block on the 12.5" barrel.

Thanks,

Marco

Barrels are actually available now I have plenty in stock.

We hope to have a new website working soon.

Marco- I have my own low profile gas block we pin on. and I'm not sure on the rest of it I've not built one with those features yet.

If we get any 14.5 in they will still probably be a mid-length gas system.

Thanks
Monty

I was just looking at your barrels on your new website; I want a 16" one, but would like a bit more info. Now you have a Midweight and a Lightweight barrel; are these new production barrels different from the ones you've done in the past? I was looking at one on Rainier's website, and it looks different than the ones on yours....the one on Rainier's looks like a Government profile, but without the M203 notch: it has a fat diameter in front of the gas block, and skinny under the handguards (like the ones in SMGLee's pics at the top of this page), while the ones on your website look different in terms of profile; could you please give us the outside diameter under the handguards, and in front of the gas block, for each type?. This will help me decide which to get; thank you for your time!

wild_wild_wes

01-14-10, 04:06

If we get any 14.5 in they will still probably be a mid-length gas system.

How firm is this? Besides a 16" I also need a 14.5", and I was planning on getting two of the 16s and having my gunsmith chop one down to 14.5, but I'd much rather have a 14.5 direct from you.

Thanks!

rob_s

01-14-10, 05:43

Maybe I missed it. Weight on 16" middy lightweight?

grinch

01-14-10, 10:03

Wes- The ones on my website are of the mid-weight I hope to have pics up soon of the light weight. The pics in this post are of the light weight barrels. If we do the 14.5in it will be a cut down version of our 16in light weight so it will be a mid length gas system. If you want a smith to cut it down that will work to I know there is a debate weather chrome will flak or not but after talking with a couple reputable barrel hard chrome shops they assure me this is not an issue with the hard chrome they use for barrels.

Light weight
12.5in--1lbs 5oz
16in----1lbs 9.9oz

Mid wt
16in---1lbs 15oz

The light weights are gov profile under the hand guard and step down to .680 in front of the gas block. The mid weight is .750 under the hand guard and .740 in front of the gas block.

Thanks
Monty

wild_wild_wes

01-14-10, 22:32

Thanks for the info, Monty! I will definitly be ordering a 16" barrel.

As for the 14.5s....are you reasonably sure you will produce these? Any idea of a time frame?

biodegraded

01-14-10, 23:37

I am also interested in a lightweight, shortest carbine I can get without having to mess with NFA stuff. But since getting a middy 16" I can't go back to a carbine gas system unit. Monty, if you make a 14.5" LW with the same specs as the 16" LW you listed above, I will buy two. I don't much care what flash suppressor gets permanently attached.

Wes- Yes we have so many 16in barrels we will cut some of them down in batches to 14.5in now that I'm sure cutting a chrome barrel is not an issue.

Impact- thanks!

Bio-I will be gone to shot this next week but as soon as I get back I'll start working on getting this done.

Thanks

I will run a few of the barrels and get it worked out before I get them to you guys this is something I may do every now and again.

Thanks
Monty

wild_wild_wes

01-20-10, 23:14

One more question Monty....what I really want is a true lightweight barrel; do you have the ability to machine the barrel in front of the front sight base down to a reasonable diameter, say .600", on a special order basis? Along with trimming back to 14.5", or course.

grinch

01-21-10, 01:15

Wes,

Sorry I do not mine are .680 in front of the gas block though.

Thanks
Monty

Wes,

Sorry I do not mine are .680 in front of the gas block though.

.680 is not too heavy; I can live with it!

AR guys are such pains to deal with, eh.

mtdawg169

01-21-10, 22:39

Monte, Couple of questions. First, are these specs applicable to both the light weight & mid weight barrels? Same accuracy guarantee for both weights? and finally, I hope this isn't a dumb question, but what is a tapper bore?

-16inch mid length

-cold hammer forged

-M4 extended feed ramp

-1:7 right hand twist with 5.56 Chamber

-tapper bore

-HP/MPI tested

-Extra thick Chrome lining

-Mil Spec Phosphate finish

-***Guaranteed capable of 1 MOA or better accuracy with proper ammunition***

-***Service life three times a standard barrel***

wild_wild_wes

01-21-10, 23:41

Tapered bore. A bore with taper to it.

Bigboote

01-22-10, 08:18

That 12.5" lightweight upper with CHF barrel is badass, and exactly what I've been trying to find for my first SBR these last couple years. The 16" lightweight looks fantastic, too. Monty, you're gonna melt my credit card.

mtdawg169

01-22-10, 17:01

Tapered bore. A bore with taper to it.

At the risk of further exposing my ignorance, what is the purpose / benefits of a tapered bore?

ddemis

01-23-10, 11:18

A 14.5 inch with a mid length gas system, I can live with that. I would love to place an order but cutting down a 16 inch barrel with crome lining ? Since I do not manufacture barrels is this a big deal. Can anyone shed some light on how it might affect the crome and crown on the end of the barrel. Thanks for any info.

grinch

01-23-10, 12:46

The taper bore is that the bore dimension is slightly smaller at the muzzle end this help accuracy. You may notice that the match shooters will not use standard chrome lined barrels since chrome can not be laid consistently through the bore there will always be variations in the chrome thickness. The taper bore gets tighter as the you get closer to the muzzle this negates any negative affects of chrome lining inconsistencies and ensures that it will not have any negative effects on accuracy.

So the taper bore is to enhance accuracy on chrome lined barrels.

Cutting a chrome lined barrel- I used to be very skeptical about this but after talking with the barrel chroming shop they assure me that flaking around the muzzle after cutting is NOT an issue. I've check this with two of the best barrel chroming shops in the country and they both assured me this is not an issue. I've since cut some test barrels and this has shown itself to be correct as I've not seen any negative impacts from the cutting on the test barrels.

Thanks
Monty

I just viewed your site and registered. I'm looking to purchase one of the midlength barrels that have been cut to 14.5".

Let me know how!

Can you mount/provide a standard "F" marked front sight base on your barrels?

Thanks,

openbolt

SuicideHz

01-29-10, 15:23

I think they are sold "bare". I can sell you one that's not yet been drilled for next to nothing and you can send it all off to Steve at ADCO and have it pinned.

Does anyone know if the seat area is long enough for a standard FSB? As an example Noveske SS barrels do not have enough seat area for a standard FSB...

Col_Crocs

01-29-10, 18:57

Havent handled their barrels personally but from what I can see, I think so. Their GB is a lot like Larue's where it is extended to cover the front FSB pin hole. I checkout out a few pics of the Larue GB and it touches the tip of the .750" area like the Centurion Arms GB does. GTG IMHO.
Grinch should be along shortly to clarify this. :D

wild_wild_wes

01-29-10, 21:02

Yes, they will take a standard FSB.

grinch

01-30-10, 00:07

The barrels are ready to ship in the bare I have a few on hand with gas blocks pinned already and will get more of them up for you guys and I can pin the standard front sight post too I will order some soon so I can get that going for you guys. I was hoping to have some cut to 14.5in but it will probably happen the beginning on next week when I'm done I'll post a pic here for you all to see.

mhall

01-31-10, 14:20

Monty,
one question reguarding your barrels. does it take the standard mid length gas tube or a special length one? if this has been covered please forgive me as i did not see it on either this thread or on your website. thank you for your time,Mike Hall

wild_wild_wes

01-31-10, 15:21

They take the standard midlength gas tube.

mhall

01-31-10, 18:14

Wes,
thanks for answering my question. i was hoping that they used the standard mid-length tube instead of something that was hard to get. i appreciate it,Mike

Chris Rhines

01-31-10, 21:44

That's a nice looking barrel. One question - how far out does the accuracy guarantee hold? Will these barrels hold 4" @ 400 yards?

Thanks,
Chris

grinch

02-01-10, 00:49

Mhall,

Wes is correct and thank you Wes for answering.

Chris,

I'll guarantee it to 100 with proper ammo to go past that is a sticky wicket that depends more on the shooter, environmental conditions and ammo selection then the barrel. I will say this though I've shot an 8 inch group at 800 yards with these barrels using 77gr black hills MK262 that was one of the reasons I decided I wanted to sell them.

SuicideHz

02-01-10, 12:02

Holy crap Monty!!! That's an awesome group from a non-Noveske :p

Seriously, I'll be in love with that barrel when you get those cut down. I'm giddy like a school girl.

That's just awesome- the accuracy, not my giddiness ;)

biodegraded

02-01-10, 15:10

I was going to PM a few questions, but decided there may be others who would like to see the replies. As noted in my posts above, I'm all over the 14.5" offering and was wondering:

Can I get you to permanently install a FH? I would just as soon not have to arrange for a third party to do that. (I'm not doing NFA papers myself.)

Can I specify that a pinned low profile gas block be installed by you?

Would you be willing to make a complete upper based on the barrels? PM if so to work out a build.

Thanks,
Keith

SuicideHz

02-02-10, 00:55

SuicideHz- yea I was pretty happy but it proved that the barrel could do it and that is what help convince me.

Keith- I can build and upper from these and I can do the pinned gas block. The only way to do the pinned flash hider is to build the entire upper.

Thanks
Monty

Wes- yup a light weight contour did it. We had shot yard lines from 100-800 so by the time we got back there I was dialed in with the system. It was a 10 shot group using a leupold 3-9 power.

Thanks
Monty

02-03-10, 12:35

Two followup questions.

Diameter under handguards? (sorry if I missed it, re-read the thread and didn't see it)
Weight of 16" mid lightweight barrel after chopping and re-threading at 14.5"?

Col_Crocs

02-03-10, 18:36

A follow to Rob's 14.5 question...
Since the first batch of 14.5 middys are to be cut down from 16's, how significant will the loss in tapering be compared to the "factory" 16 or 12 which I assume are rifled with the same preset taper measurement at the end?
Also, I see on another site that CA barrel crowns are both chamfered and recessed with the chrome extending all the way out to the entire recessed surface (this particular feature I really like). How are the 14.5 middys' re-crowning finished? Are they re-chromed to come out just like the factory crowns or just phosphated?

BigJoe

02-03-10, 20:51

There is no taper in front of the gas block, just a straight .680".

Col_Crocs

02-03-10, 23:37

Thanks for responding Wes. Sorry, I shouldve been more clear. I was referring to the tapered bore feature of CA HF barrels for added accuracy and not the exterior profile.

grinch

02-04-10, 00:43

Rob-its a gov profile under the handguards and I'll get the weight here soon.

Crocs-it will not have a recessed crown and yes some not all of the tapper will be gone from the bore.

Joe- rog will check it tomorrow

Thanks
Monty

Col_Crocs

02-04-10, 00:47

Thanks Grinch! a couple of final clarifications... The factory 16 mid weight, 16 light and 12 light HF barrels all still come with the same chromed recessed crowns as well as the same tapered bore dimensions and only differ slightly in exterior profiles/dimensions? lastly, what are the actual markings on your current barrels? The ones on the first page are stamped with Centurion Arms HF 1-7 and I see some around the web stamped with the CA logo...

SuicideHz

02-04-10, 15:45

Monty-

You guys get those 14.5s cut yet?

I just noticed your 12.5s are midlength systems too, but are lightweight. I'm considering one of those instead but don't want a huge POI shift between supressed and unsupressed. I have a 21 oz. Gemtech G5 that will be hanging off of the end...

rob_s

02-04-10, 15:51

I just noticed your 12.5s are midlength systems too,

how did you arrive at that conclusion? The pic that starts this thread shows a 12.5" with carbine gas system, and 16" with mid-length gas system. Is a mid-length gas even possible on a 12.5"?

http://photos.imageevent.com/smglee/clt2/huge/P1020080.jpg

SuicideHz

02-04-10, 16:00

The chart on the page is where I got the info.

http://www.centurionarms.com/index.php?page=shop.product_details&flypage=flypage_images.tpl&product_id=45&category_id=19&option=com_virtuemart&Itemid=133

Of course it can be done- probably with an enlarge gas port and probably not a problem if always run suppressed without any work done.

rob_s

02-04-10, 16:58

Hmmm, interesting. Since the pic shows one thing and the website shows another.

I can see where there is room for it, I just haven't ever seen it and I'm not sure if there's a benefit or not in terms of operation.

SMGLee

02-04-10, 17:37

the 12.5 is a carbine length...

Col_Crocs

02-04-10, 18:17

SMG, any ideas what the current barrel markings are? I see the ones here stamped Centurion Arms HF 1-7 and I see some around the web stamped with the CA logo...
Also more importantly, what crowns do the current ones come with? The barrel I saw stamped with the CA logo showed a beautiful chromed recessed crown which I dont see judging from the angle of the photos on the thread.

wild_wild_wes

02-04-10, 19:46

Mine was stamped stamped Centurion Arms HF 1-7; no CA logo.

grinch

02-05-10, 00:49

The 12.5in is a carbine length that was a commo error with me and the web guy I will get it corrected.

I have some of both on hand now the no logo ones were from a shorter previous run of barrels the current large run has the logo on them.

The crown is a flat crown on the current run of barrels.

Thanks

As usual I see great things coming from CA and Monty. First the MK12 and now this. Any plans for a MK18 setup or a 10.3"-10.5" Barrel?

Col_Crocs

02-05-10, 09:27

Thanks for the response Wes and Monty. I really appreciate you guys addressing a query as superficial and I guess cosmetic as barrel markings.
As for the flat crowns, any reasons as to why youve decided to go with flat over the recessed? Also, am I correct to assume chroming still goes out all the way to the chamfered portion of the crown atleast?

Monty is to the DI AR15 what LAV is to the 1911.

He is an absolute student to the design and perhaps one of, if not the premier SME of any of the current real world end users.

I have talked for many hours with Monty on what the best Barrel Lengths of a DI AR15 variant are and why. We both shared the opinion that a 16.1" Barrel was optimum for the 5.56 cartridge in many respects. And in a shorty platform the 12.5" was perhaps best for a DI gun.

Perhaps Monty can elaborate on these barrel length choices for some prospective. Personally I see no allure in a 14.5" barrel. The DI ones that are currently being fielded by many of our overseas end users are rarely being toted outside LW Operations; and even these are currently being displaced by 7.62 weapons in the major LW theater.

To those that would prefer a 14.5" AR15 over a 16.1" one, Why? Is there something gained in a shorter by 1.5" barrel that I am missing? If a short barrel is what one seeks then the 12.5" seems to be the right choice for so many more reasons.

Monty? What say you?

wild_wild_wes

02-06-10, 15:53

The 14.5" inch is the shortest I can legally own in my state.

Isn't 14.5" still SBR restricted by NFA and CA State Law?

My 14.5" middy BCM, standard profile, weighs less and swings target-to-target faster than 16" middy Noveske, lightweight profile. If I knew what I know about this now, I wouldn't have had it cut because the difference is too small to me, but nonetheless the difference is there. For those who want to cut as much weight as possible out of their rifles, for right or wrong reasons, this could be important, who knows...
I would've absolutely positively preferred 12.5, if not for three letters attached to it - NFA. Or NFE, if you will...

P.S. I think Wes and I imply 14.5+pinned FH as shortest non-NFA option.

I would've absolutely positively preferred 12.5, if not for three letters attached to it - NFA. Or NFE, if you will...

P.S. I think Wes and I imply 14.5+pinned FH as shortest non-NFA option.

Bringing it to 16 or so inches?

I think I see what you are saying but it still doesn't completely register in my head. I am a little slow sometimes.

14.5 will give me the lightest non-NFA w/ a permananent FH. only reason I want one.

I think I am going with 1200* silver solder instead of pinning. I will try it on an SBR lower first anf then solder it when I know I like it.

Check. I see that there is a different perspective based on where you are coming from. If one lived in a state that allowed it opting to go NFA and running a 12.5" would be worth the effort. For those who don't then I guess 14.5 with a perm attached FH is the shortest and lightest possible option. That 1.5" of steel and FH may pose more to handle on a micro scale than a 16" w/ FH.

Reading your posts on this and other websites for a few years now, I have not noticed that.

Yes. The above mentioned 14.5 BCM has a PWS FH pinned for a permanent length of 16.1. It is slightly shorter than 16 Noveske with KAC QD FH, but it is lighter. Since the weight is taken off at the very end of a barrel, it is more noticeable than if this same weight were to be shaved off everywhere else (i.e. lighter optic etc.).

I do want to repeat that I wouldn't've done it again. The difference is marginal. Pinning of FH limits the choice of handguards unless one is OK with "jailing" of his preferred handguard by a FH. In retrospect, none of that was worth it for me.

This I why I'm lobbying for a true Lightweight barrel here.

Heavier barrels have their place; I ordered a Centurion 16" midweight for that role. However, there is also a need for very good quality Lightweight barrels, for the reason Rob mentioned- the lightest rifle possible. People seem to forget that ARs are supposed to be lightweight weapons; A good small arms engineer ought to see the need. Three centuries of firearms design tells us that barrels go from fat to skinny, chamber to muzzle, and not the other way around.

I hate the Government profile with a bloody passion. It makes no sense from an engineering standpoint, because it was designed by government comittie; none of us are going to be using our rifles to pry open crates!The extra weight hanging off the barrel serves no need. Get rid of it. When I get my Centurion "Lightweight" 14.5" barrel, the first thing that I will do is have my gunsmith mill down the "government" bit to a proper .600"- which is a shame to do to a hammer-forged barrel, which should designed with the correct profile straight from the manufacturer.

My state allows SBRs, and I already have three, one of which sports an 11.5" .625" dia. barrel. But there is a lot to be said for not paying the extra $200, not having the gun on paper, etc. Traveling is less of a hassle, "the man" in general is less of a hassle, and it's something I can loan out to another shooter without issue.

It's funny, I never would have done it before and have talked others down off the cliff, and still WOULDN'T do it for my only AR, but I have changed my mind with all these lighter-weight options available now. I'm going to do a 14.5" pinned Brakeout w/ 9.0 Troy Vtac Extreme.

Rob,

If your lightweight 14.5 inch is running midlength gas system the 9" handguard won't cover your gas block. Can't wait to see some pictures.

My state allows SBRs too; I wouldn't get one on principle, but that's a separate discussion.

Yep, I know you've argued against it before, and I read your posts on this matter before I did mine. Just shows how people's needs, opinions and reasons may change over time. Mine, besides weight and length reduction, was also a multifaceted learning project, i.e.:
the magnitude of difference vs. 16" 0.625 Noveske?
what happens with accuracy if bbl is cut-down?
can 14.5 middy run reliably across wide range of ammo and conditions? etc.

Speaking of last two, and in attempt to steer this thread back to discussion of Centurion CHF barrels:
Monty, how did you figure out a gas port size for your 14.5 middies, and, of more interest, what accuracy difference do you see between your 16" CHF vs 16" Recce barrels?

grinch

02-07-10, 20:56

I chose 16in and 12.5in as I feel these are the best lengths for the cartridge. The 16in for me is the most versatile. Its the minimum legal length with out giving up the ability to change flash hiders and breaks and try new cans ect. I feel that a 16in give me what I need in performance from a 5.56 rifle if I need more that what that offers I'm in an environment that its time to step up to a 7.62. The Recce rifle that later turned into the MK12 program started as a 16in precision rifle and does a great job as a precision weapon in 5.56. If I wanted a carbine as an assaulter or as a general purpose carbine then I'm a fan of the 12.5in barrel its the shortest you can get and still have good terminal performance out of a large variety of ammunition that is on the market. The 12.5 also gives you enough dwell time to be reliable with a wider variety of ammo and in a wider variety of environments it just has a wider operation envelope then the shorter barrels and is a GREAT all around length.

YVK- There are a few little tricks you can do to figure out the gas port size ;) I'm going to reserve any accuracy guarantee for right now on the cut barrels not because of the chrome but because of the taper bore and the fact that you are removing some of it. The Recce will hold its accuracy better during heavier strings of fire being heavier it will absorb the heat better also a heavier rifle is much easier to shoot. The chamber in the Recce is designed for SMK ogive bullet set to magazine length and have minimum jump into the lands and grooves. It will shoot better with those bullets then the hammer forged barrels but for practical accuracy its kinda splitting hairs.

wild_wild_wes

02-07-10, 22:33

Ahhh, there are two paradigms for 5.56 barrel lengths: 10", 14.5", and 18"; or 12.5", 16", 20".

Monty seems like a #2 guy, except he ditches the 20" and goes straight to 7.62!

grinch

02-08-10, 01:22

Wes- you are correct I lean toward the longer batch of barrels.:D I do look forward to the SCAR heavies hitting the market and will be interested in watching how it changes and develops over the next 10 years or so.

I was not able to get the batch cut to 14.5 last week it was a crazy week I hope to get it done next week.

Monty is to the DI AR15 what LAV is to the 1911.

He is an absolute student to the design and perhaps one of, if not the premier SME of any of the current real world end users.

Per one of the guys from the teams out of Coronado who I checked in (I work at the base hotel on Vandenberg AFB), "Monty is the 5.56 DUDE on the West coast". Given the enthusiasm with which he said that, it was pretty clear he holds Monty's work in very high regard and so I look forward to one of his uppers once my eye surgery is paid for...

I received my 16" LW in the mail the other day and figured I'd post some pics and a small review. Downside is that I have not received all of my parts to assemble the rifle and shoot yet, but, within the next week I'll be shooting and let everyone know!

The quality appears to be exceptional. The rifling (as should be for a HF barrel) Is very clean, deep, and sharp. The Park is very nice, however, I ended up wearing some of it off installing my gas block as the fit was tight. Good thing. A little oil on the park and it darkened up real nice.

Overall, extremely happy and can't wait to shoot it!

02-18-10, 22:23

Monty, do you have an update on the 14.5" LW project?

Regarding Rana's question of why 14.5" - same as others have mentioned: shortest I can go without NFA shenanigans. I agree that 12.5" is a better technical solution for CQB, but the legal solution in my case dictates 14.5" with a permanent FH.

I already have a 16" middy (Noveske), otherwise I'd get a 16" LW from Monty, too. Actually, it's hard to not spring for one even though I don't "need" it. Then there's the SPR Siren call. I don't know if I should be glad Monty's making stuff or to curse him...

03-09-10, 00:20

I managed to squeeze some range time in yesterday. Let me preface this pic by admitting that I'm a terrible shot, but I don't see many groups posted with this barrel. Here goes:

Indoor range, 25 yards, 68F, no wind using gun show cheap reloads (I know, I know) and iron sights. This was to confirm a previous 50 yard IBZ. Sadly these are the best groups I've shot with just irons using this ammo. I've done a little better with Centurion ammo at 50yds but I don't have pics of that group. POA was the top of the black circle. I don't really show off what the barrel can do except for the 4 rounds stacked on top of each other. Yes, they were consecutive trigger pulls.

http://web.me.com/supermarkus/iWeb/Site/Centurion%20upper_files/IMG_2754.jpg

I'm willing to bet Monty can build me an upper with this barrel that can out shoot this frankengun I cobbled together with his barrel. I'm saving up for a proper Centurion upper later this year.

I think that these are a great option on the market. Ignoring the CHF aspect we now have (in order from heaviest to lightest) the Noveske N4, Centurion, BCM, and Daniel Defense barrel profiles.

Noveske N4 are not available barrel-only. Very expensive. No midlength gas either.

BCM and DD do not currently have any 16" light midlength gas barrels available.

Monty, Im also curious, when you did 14.5 midlength cut downs, did you try running them with the ports as is -- at 16 mid spec size?
Im wondering if this is functionally feasible the same way a 14.5" carbine can be cut down to 12.5" without having to open up the port.
It would theoretically make for an even softer shooting system.

That is correct I did not need to open the gas port at all for it to run.

08-04-10, 20:48

Ive had a few people ask me to post some accuracy reports with the 16" L/W barrel. So here is a picture of the rifle and my results at a 25yd range.

http://i825.photobucket.com/albums/zz179/556mp/IMG_0972.jpg

My range session began with zeroing the rifle. I started with sighting in my new EoTech using a 55gr BT hand-load. Loaded to duplicate M193. Cold barrel groups were decent. My groups at 25yd were approximately the size of a dime. Mind you the rifle could do better than that with a quality shooter behind it. I was not in the game today. Regardless, the session continued. I was calling the shots and they were hitting where I called them. Shooter error played a large part in the mediocre results.

So, what I decided to do in order to overcome this and display some of the potential of this barrel was shoot a 20 shot group. Now, I had already put over 100 rounds down range in a relatively short period of time. The gun was HOT. The handguard was hot to the touch forward of the VFG. I splashed a little water on the barrel to see just how hot it was and the water instantly evaporated.

Anyway... This was shot using 77gr Sierra Matchkings loaded in new Winchester brass. The powder load was 24gr of Varget, measured in a POS Lee powder measurer. Not the best results with this Lee product, but its what I had.

As you can see there are five or so "fliers." Minus the fliers the group can be covered with a nickle. I did not have the best of results today, and had a limited distance to shoot. But overall I am satisfied with the results as I know the gun will shoot better than I can make it. This weekend I'll pick up some BH 77gr and have my buddy blast some rounds out at 100yd with a cold barrel and post those results.

Monty,

I've searched through several threads and your website and still wondering if you sell a matched BCG for your barrels. I just feel better knowing at least the bolt is coming from the same manufacture and properly head spaced to their barrels. I know any mil-spec bolt should work, but I'm just weird like that.

Lastly, do you folks offer MIL/LEO discounts?

Thanks...

I can head space a bolt for you and sell that with the barrel if you wish to ensure it is correct.

Thanks

Almost have enough $$ socked away to buy one of your barrels Monty. Now I just need to deciede if I want a 16" or a 14.5". This will not be going on my SBR lower, as I want an non-NFA upper I can bring across state lines without hassle so if I get the 14.5" I will be pinning a Battlecomp 1.5 to it.

I suppose I should just ask the source. Monty, in your expert opinion, would you say you recoil impulse from the 14.5" is that much smoother than the 16" to facilitate the hassle of a perm-pinned muzzle device?

grinch

09-03-10, 16:52

I would say that any difference is not significant and go with the 16in since you will not need to perm attach anything and keep your options open.

Thanks

Monty have you done an accuracy test on the 14.5 cut down barrels that you can report? Did you notice any appreciable decrease in accuracy in the 14.5" from the 16" barrel's accuracy?

I thought the 14.5s are now manufactured that way rather than being cut down.

What is the Gas Port size on the midlength?

Are all of the barrels optimized for 77 gr. match ammo?

According to the website the Recce and MK12 barrels are optimized for use with MK262 (Black Hills 77gr equivalent), the hammer forged barrels are standard 5.56 chamber.

not to bring back an old thread but i stumbled across it.
if i read correctly you are not adjusting gas port size with the cut 14.5 mid lengths.

are there any reliability problems as far as cold weather shooting or
firing under powered ammo when using a proper buffer.

also does the light weight profile take heat better being it is made out of machine gun spec steel compared to standard.

thanks

Just "discovered" Centurion arms barrels, after being able to score a Noveske matching receiver set. (Coldhandarms, gtg!)

Was in the middle of building a DD upper (16" mid, CHF), and got to thinking about maybe putting that DD barrel on the Noveske, but after reading about Centurion am really tempted. And still would need to get another tube.....
(Looks like I'll be building a recce upper.)
Without questioning either their undoubtedly excellent products, what would be the better match for the Noveske?
Don't have the need/bread for the Noveske barrel, and it appears they both -Centurion & Noveske -get barrels from pac-nor, but that's neither here nor there.
Thanks.

While neither here nor there, the belief that the chrome lined hammer forged barrels relevant to this thread are from pac nor is misinformation as far as I have researched. When I purchased mine they were from the FN forge like the Noveske chrome lined barrels and turned down to custom profiles. Either barrel will do fine. The DD can be had in a lighter profile if you prefer a lightweight gun.

So neither Noveske nor Centurion gets any barrels from pac-nor, or only certain kinds?
(this could get really confusing..)

Planning to finish the DD upper (receiver/barrel/bcg) as a regular mid, then build light weight upper with the Noveske receiver and Centurion CHF lightweight barrel. (BCM or DD bcg)
Should be gtg, right?

Noveske SS barrels are from Pac-Nor. Noveske does the turning and profiling.

There was an article posted here last year where John Noveske said they are using Pac-Nor's facilities with their own tooling for their barrels, and the blanks are made to their specs.

FN is supplying some companies with CHF barrels because there are only a few CHF machines in the US. They cost a lot of money and are better for mass production not smaller companies like Noveske and Centurion.

Monty,

I posed this question in an email to you, but thought I would put it here so that it could benefit everyone.

Regarding the 14.5” barrels, are they still cut or are they now manufactured that way?

If they are cut, wouldn’t that cut off some of the taper off of the end (there was 3” at the end of a 16” if I recall correctly) so that there would only be 1.5”ish of taper?

If this is the case, would this have a slight negative effect on accuracy as compared to the 16” versions?

Thanks!

I believe he posted elsewhere the 14.5" barrels are not cut downs anymore. This was several months ago.

I assume this cuts down on the bore taper as well? If so, what effect does this have on accuracy as compared to the 16"?

My understanding of the HF process is that the taper runs the entire length of the bore, from one end to the other. I may be mistaken on this, but if that is correct, you're losing 1.5" of the total 16" and not 50% of the total taper. Either way, it sounds like Monty will still guarantee accuracy if he builds the upper.

M4Fundi

03-03-11, 18:12

It does cut some of the taper bore out but it will still shoot with or better than any of the other barrels on the market that don't have it.

Also I'm planning on pulling the 1 MOA guarantee off the barrels anyway and only applying it to the uppers. There are other factors that go into accuracy and when I ship just a barrel I have no control of the other factors of the build.

Sounds reasonable to me. You can't guarantee something that is dependent on being "greater than the sum of its parts" when you don't have control over how the "sum" is handled by someone else with your quality "parts"

Getting ready to order that Centurion Arms CHF lightweight 16" mid barrel for my Noveske receiver set, so i'm just wondering, without getting too technical, what exactly makes it that "machine-gun" steel used for this barrel - what makes it different from the D.D. barrel-steel (which would be a comparable barrel)?

It was a no, we are not offering it, but will think about it.

Just looking at my 12.5" I can tell you that it will not work as is, I can grab the calipers but I can tell you it is under .75", you could have it reprofiled and run a .625" front sight post.

Thanks. I had posted this in the other Centurion thread and someone just posted the same thing. The reason I want the Centurion is the profile, I don't want to turn it down for the FSB.

Well, how much would it affect things turning down that section? Any idea? Think I'll notice as much of a difference in accuracy when it gets hot as I would between a 14.5" standard and lightweight profile?

I've only owned be lightweight barrel, so I'm not too familiar with how it affects shorter barrels. I have a 10.5" that is a solid shooter and want the 12.5" for a couple reasons, one being the accuracy potential. I don't want to give that up though.

I think Monty could provide the best information, but it is my understanding that the thinner wall at the muzzle will open up faster with heat, so in theory you might lose a little accuracy sooner under rapid fire, but I do not think it would affect accuracy, atleast not initially. It would be a lightweight profile, so it would be comparable.

I have great results with a pencil weight DD, so I imagine the Centurion would do well. I think you just need to figure out your priorities, or wait and beg for a factory Centurion Kino :D

To be honest, I'm not sure. I would imagine the suppliers would have just one raw FSB forging and then machine teh correct diameter for the barrel.

If I had to guess, I would say yes there would be enough meat to ream.
