I’ve always liked pistol caliber carbines and more applications are coming out for them with their growing popularity.

My first AR was a 9mm Spikes. I later bought an AR57 carbine upper and mounted it on a Spike’s lower. Now I wanted to pursue a carbine that sends .45auto down range.

There are some choices in the market when you venture down this path: Thompson 45, Marlin Camp 45, Hi-Point 45, Taurus CT G2, Beretta CX4, Military Armament Corp (MAC-10), H&K USC, and KRISS 45 (I just saw Total Recall and everyone's got a KRISS in there). There are others models out there, but that’s quite the design variety already.

I went with an AR platform from Justin at CNC Guns. The criteria I made for deciding this route: date of the design, visual appeal, cost of parts to repair/replace, and familiarity…I’m a creature of habit.

I also went with this lower because my research has shown that everyone that has one loves it. It’s rare to see someone sell their CNC AR45.

LOWER

The lower assembly went in like any other lower parts kit. I’ll just note some odds and ends to this portion.

Installing the front take down will reveal that it will not go all the way through the receiver. It will still detent securely in place when the upper is mounted, but I need a punch or pen to push out the front detent for field stripping. The Yankee Hill EZ Pull Takedown Pin Set would remedy this.

The LWRC nickel Teflon had this weird green/blue color on top of the coating, and was not as shiny as the Spikes nickel boron coating. Not knowing if the coating was on or not, I called LWRC and asked about it. I love their customer service, but this time the rep seemed annoyed by my question, like she gets it a lot. “YES, the nickel Teflon coating is on there.” She said with an exhaustive sigh. Oiling makes it go away.

I got this trigger set to see for myself, what kind of trigger people are working with when they pay over 2k for an LWRC rifle. After installation of it in my AR45, I compared it with my Daniel Defense trigger in my 9mmAR and the Spike’s NiB in my 5.56.

LWRC Nickel Teflon trigger set is beefy in construction. I don’t see the disconnector or disconnector spring ever being replaced after installation. Definitely solid with tight tolerances and the springs are pretty strong too, probably because it was designed to strike a primer for a NATO7.62 out of their R.E.P.R..

I’m not going to talk badly about the trigger because I know that it does need to be broke in. However, I was a little discerned comparing the LWRC to the other two (considering the price), because it has a more noticeable longer creep to the break than the Daniel Defense. It was just as smooth but has a harder break than the Daniel Defense, so I at least have an idea when I’m about ready to send one down range. A lighter spring (JP) would change this characteristic, but again, I know that the trigger springs will soften up with use and need to be broken in. So the tension characteristic will change, but the creep has to do with the sear design. The Spikes NiB trigger has that consistent glass break feeling while shooting. Comparing the three triggers and evaluation by amount of creep and release characteristics. I would rate them in this order: Spikes, Daniel Defense, and then LWRC. You can get these trigger kits and you can judge for yourself, but this is just my opinion.

Here’s the steel magazine catch that allows un-modified grease gun magazines. It takes two roll pins to hold it in position.

http://i1157.photobucket.com/albums/p588/SCatalyst/CNC%20AR45/639b2e36.jpg

Since the pins move freely in the magazine release lever, I punched the top roll first, making installation easier. I then dropped the second roll pin in the lever and finished punching the roll pin thru while pushing the spring and lever in place, until they were centered. I had a patch of leather that I wrapped the receiver in to prevent any damage while hammering the punch.

I inserted a magazine just to see how it fits. The magazine snaps in securely, sits flush to the receiver and fits very well with very little wiggle once engaged. I shook the lower aggressively with a loaded magazine in it and it didn’t fall out. Once I pushed the steel magazine release, it drops freely out of the magwell. The steel magazine catch is a solid design.

There’s a good and bad about the LWRC end latch plate. The good is that you can take a hex to the first screw which is a dog point screw that fits in the groove on the bottom of the buffer tube ensuring consistent alignment and easy installation.

http://i1157.photobucket.com/albums/p588/SCatalyst/CNC%20AR45/e1e48956.jpg

The bad is there’s a second hex that has a pointed tip screw on the other end where when installed, grabs the castle nuts and eliminates the need to re-stake the castle nut…which won’t budge and doesn’t work. I don’t know where the design flaw is, but I’m thinking it’s the same reason why LWRC doesn’t have them on their website anymore. I don’t mind staking the castle nut anyway, it’s still a nice end latch plate.

UPPER
RMW Xtreme 16” 1:16 twist DI45 Upper w/A2 FSP and A2 flash hider 5/8x24 thread
Spikes Tactical 7” BAR
Vltor MUR-A1
LWRC Skirmish Rear BUIS

I asked Ron Williams at RMW Xtreme to build my upper assembly because he built the first purchasable DI45 upper with one in use by a Texas Ranger Special Response Team. I chose a direct impingement (DI) because it’s cleaner (my 9mm blowback gets very dirty), there’s less recoil (pertinent to FA and burst), less chances of an out of battery discharge, and I won’t be shooting cast bullets or reloads anytime soon (a language I’ll learn later).

Communications with Ron was great. He answered my many questions and I sent him specs from different uppers (Spikes billet upper and the Spikes 9mmV2) to see if he could work with either of them. He said both and any mil-spec upper would be fine because the bolt and carrier is standard size, and the upper has to have an opening for the gas tube (eliminating the Spike 9mmV1). The short ejection port door on the 9mm upper should be okay since a .45 auto casing is just as short as the 9mm casing.

I couldn’t wait for any Spike’s uppers…so I got a Vltor.

http://i1157.photobucket.com/albums/p588/SCatalyst/CNC%20AR45/fff7135f.jpg

Since I was in a neighboring city, Ron was nice enough to invite me to down to test shoot my upper when it was finished. That day was a great day shooting; clear skies, nice breeze, and a shaded shooting stand. When I pulled up, he and some of his friends were all just enjoying the early afternoon with some snacks and range time.

To test fire, I brought out 100rds of white box Winchester FMJ 230gr FMJ ball rounds. I wanted to bring the cheap stuff to see how it would handle. I didn’t bring out any steel or aluminum cased ammo. I thought that would be a bad way to break in a new barrel and that would be a test for later time.

The ejection port door was opened and squared off a little because the .45 casing cannot hit otherwise it threatens to jam.

This is before…

The Spikes BAR had to be trimmed for the lower to mount to the CNC. You can see the exposed metal here. This eventually calls for Cerakote sometime in the future.

Ron has had his DI uppers working on a variety of lowers. His experience with a CNC lower, proved to be helpful if the feed lips on the grease gun magazine were opened/ flared slightly. He used an adjustable wrench to open/flare out the feed lips 1/8th to 3/16th of an inch.

On the left, is a normal grease gun magazine. On the right is grease gun feed lips opened.

http://i1157.photobucket.com/albums/p588/SCatalyst/CNC%20AR45/9ca44036.jpg

The CNC AR45 design puts the magazine more forward on the receiver.

http://i1157.photobucket.com/albums/p588/SCatalyst/CNC%20AR45/fd268ed8.jpg

I believe the lower was designed this way so the round doesn’t have far to travel and reducing the odds of a FTFeed. The 230gr ball rounds are pretty blunt, especially self-defense hollow-points. Such a bulky round (or any round for that matter) shouldn’t have to hit or rattle around a whole lot to be chambered.

Flaring out the magazine allows the round to angle up sooner and be more in line to find its home.

http://i1157.photobucket.com/albums/p588/SCatalyst/CNC%20AR45/65bff660.jpg
http://i1157.photobucket.com/albums/p588/SCatalyst/CNC%20AR45/be3715a3.jpg

Doing this also gives the bolt less resistance to push the round into the chamber, giving more of a perpetual smooth engagement in battery, and smoother cycling. I’m glad Ron educated me on this. It’s such a simple mod that takes advantage of the CNC design and it’s costless.

It’s free of the magazine feed lips at this point.

Bolt pushing round to battery.

http://i1157.photobucket.com/albums/p588/SCatalyst/CNC%20AR45/b1b94067.jpg

No special buffer was used for this application. Ron also said he doesn’t understand why some believe that a heavy buffer is needed. He said a standard carbine buffer will do fine because between the hammer spring and buffer spring being pushed, anything greater can cause the system to short cycle. He even told me to put my Spikes ST-T2 tungsten buffer away and handed me a standard carbine buffer. I was happy to hear this because it saves me money.

Here you can see the low profile gas block is seated close to the receiver. From the front of the gas block to the receiver measures 2”. Diameter is .875 at the journal. Ron Williams can use carbine to rifle rails without issue since the gas system is short.

http://i1157.photobucket.com/albums/p588/SCatalyst/CNC%20AR45/b3256a9f.jpg

The barrel nut had to be taken down some to accommodate the gas block being so close, which is why you see there was only one set of screws (4) holding the Spikes 7” BAR in place. I didn’t have a problem with this since I see the Troy VTAC Alpha using only 3 screws around the barrel nut and the Troy VTAC using only two at the bottom as a clamp.

http://i1157.photobucket.com/albums/p588/SCatalyst/CNC%20AR45/75e66d5d.jpg

The test shoot was awesome, the AR45 RMW DI45 cycles and shoots like a dream. It chambered easily and the spent casings ejected aggressively at 4 o’clock, indicating that there was no slowing of the bolt. Using a brand new BCG, barrel, and lower, I had 0 FTF/FTE out of a 100rd value pack of white box Winchesters. Zero, zilch, no problems with the test fire. I thought that was amazing. I even dumped two magazines of rounds down the barrel as if my life depended on it and it cycled like a sewing machine. Even my SIG P226 TACOPS had 1 FTFeed during the break-in period.

I’m very happy with the RMW Xtreme DI45 upper, and having the opportunity to meet up with him and talk shop about firearms was fun and an educational experience. He definitely knows his stuff. This will not be the last DI45 upper I request from Ron Williams.

Overall, I love this rifle, but I do have a few points of contention. This complaint has nothing to do with function, but more or less cosmetic. The upper and lower don’t match up the way I thought it would. This is purely my fault and I could have done more research on this.

I talked to a gentleman at DDLES who said that they’re coming out with a lower that is dedicated to Glock 21 magazines...in 2 weeks! Meaning that I can use the DI45 upper the Ron made for me with the Vltor MURA1 and get a DDLES Vltor matching lower that takes Glock 21 magazines.

I’ll have the best of both worlds CNC AR45 lower and a DDLES Glock 21 lower, both on RMW Xtreme DI45 uppers.

I’m excited. I’ll keep you posted when I get that one too. I’ll ask Ron to help me make it work. He got a 9mm DI upper to work with a DDLES 9mm lower.

Great post. What was the cost for the lower? Any idea on what kind of FPS you were getting on the WWB 230gr ball?

SCatalyst
08-10-12, 18:11
Thanks bro, I didn't chrono the WWB unfortunately. With sweat in my eyes, these were from 25 yards using the iron sights.

http://i381.photobucket.com/albums/oo251/CairoUmanos/Random%20Pics/rangereport1.jpg

I don't know what they were shooting at, but these were groupings by two other shooters, same distance using iron sights.

http://i381.photobucket.com/albums/oo251/CairoUmanos/Random%20Pics/rangereport.jpg

I brought out the 9mm AR that uses a blowback system to compare. The difference is significant. The 9mm AR definitely had more kick than the direct impingement(DI) AR45. The blowback also had this weird yoyo effect feeling when fired.

Shooters need the heavy buffer on an blowback AR45 but not for DI because of the unlocking step.

Everyone that shot both rifles had the opinion that the DI was smoother and more enjoyable to shoot than the blowback. Even a 110lbs girl my friend brought to the range, said she could feel the difference and liked the DI system better. Shooters that loved my blowback 9mm AR, now looked at it as archaic.

I still love my 9mm AR, I'm building another one.

SCatalyst
08-10-12, 18:22
Oh yeah, $465 for the lower in my hands. But that's with a $50 transfer fee. I know there's other places that have cheaper transfer fees, but I've been a regular where I transfer my receivers to.

I also could have chosen a cheaper lower and method, but I'm a 'dedicated' kind of guy. ;)

What gave you the idea for flaring the M3 mags?

I'm wondering if you could convert existing blow back 9s to DI. I never understood the recoil impulse of blow back 9s. Con-paired to the MP5. The MP5 shoots like a 22.

The price of the 45 lower is worth it. Have you noticed any problems with the bent feed lips on the grease gun mags, are they holding the rounds or are they prone to slip out with the bent feed lips? I hate mags that lose rds sitting in a rifle case.

I really need to look into this. I love 45acp sub guns. What was your total cost of the rifle?

As long as the upper receiver has a hole at the top for a gas tube you can convert it. You would need a new barrel that accepts a DI bolt, gas tube, gas block, and DI bolt of course. Once a barrel extension is installed on a barrel, I believe it cannot be removed because there's a one way pin that is pressed in to ensure solidarity.

You can have RMW Extreme re-build the upper for you, it can help you eliminate the guess work; where the port hole should be, barrel extension key fitting, etc..

I haven't shot an MP5, but would love to see how it works first hand.

That's a good question, I haven't noticed any problems of rounds slipping out. The rounds do become free of the feed lips earlier, but if I dropped a full magazine at the right angle, I can see it losing the top round but not a '30 pickup' game. Original grease gun magazines are steel, I'm not sure what the aftermarket stuff is made of.

The cost is priceless.:D

I will say I spent as much as the low end price range for a HK USC and KRISS Vector. But that included the trigger and furniture I wanted, and it's on an application I understand.

I haven't stretched AR45's legs out to 100 yards yet. I've read that it can be pretty consistant hitting a 8x8 target 100yds on iron sights.

So this can be a little overboard, but I was thinking about mounting some optic with a magnifier like an Eotech XPS with G33 STS or an Aimpoint CompM4, Aimpoint magnifier, and the LaRue LT755 Pivot Mount.

I think this would be more fun knowing I could plink at longer distances with ease.

Has anyone put an optic on their .45auto carbine with a 16" barrel? What kind of results did you get?

Good looking out, I'll look that up.

But now I have to save for the DDLES Glock 21 lower (if they release them on time), 27 round Glock magazines, and more CNC AR45 lowers.

08-23-12, 23:20
Kinda off topic, but the .45 auto will operate great for a DI application, but research shows the 9mm luger in DI is a NO-GO... unless you reload your own.

SCatalyst.....Thanks for a great review; It's funny how I just happened to stumble across this thread, as Ron currently has a bunch of my parts, and I'm awaiting him to do my build for a .45 DI upper.

However, I'm using a Bazooka Bro's lower (SBRed) and Ron is building the upper with around an 8" barrel, to work with my 7" carbine length rail. I wanted to keep the overall length pretty short, as I will be runnig a can.

It's nice to here you say such great things about Ron/RMW Extreme, I know I'll be getting one bad ass upper when it's done.

I'll be sure to post a pic when mines done.

How many rounds do you have through yours now; any FTF/FTE; have you tried running any hollow point rounds, or self defense loads through it, do they feed ok???

Also, tell me about the buffer you are using; did you have to take the weights out????

Do you know anything about the bolt he uses, or what he has to do to it to make it .45 ACP?? Do you have any pics of the bolt?

Are any of the locking lugs removed for the round to feed in? Any other pics of the feed ramp/barrel extension? (can't quite tell in that one pic you have)

Thanks again for that EXCELLENT review

I'm happy to do it, this is fun for me. I haven't seen a detailed review of one so I thought I would do it. I wanted specific parts too and asked him to do his magic with it. I was happy when he told me he could work with it.



I'm using a Bazooka Bro's lower (SBRed). I wanted to keep the overall length pretty short, as I will be runnig a can.
I'm jealous, I have to wait for a little more financial stability before I start telling the misses I'm submitting forms for stamps. Ron did mention something about how he liked how he could manipulate the height of the magazine for the BAZ45. He’s had great success with both the AR45 and BAZ45.



It's nice to here you say such great things about Ron/RMW Extreme, I know I'll be getting one bad ass upper when it's done.
Yeah, he and his friends are a good bunch. While I was out there, they were testing out a LW lower that they shaved out to take G21 magazines. I wanted to take pics, but it wasn’t my firearm.

I’m sure you’ll love the upper when it’s ready. I was thinking of asking him to make me an extra bolt and maybe some 2 extra extractors. I want to test the limits of it and run steel casings till it breaks the extractor. Then use aluminum casings till it breaks the next extractor. Then report findings.


I'll be sure to post a pic when mines done.
Please do.


How many rounds do you have through yours now; any FTF/FTE; have you tried running any hollow point rounds, or self defense loads through it, do they feed ok???
Honestly, after firing my new toy, I held off on ammo purchases so I could start collecting parts for the next build 45auto lower.:D

So I haven’t run self defense ammo thru it yet, but I did see a video of someone using 45SUPER (http://www.youtube.com/watch?v=QUY_8TjV4uE) out of their barrel. So I don’t see it as a future problem for mine…other than getting loud.:cool:



Also, tell me about the buffer you are using; did you have to take the weights out????
I have to weigh the buffer when I find a scale, because it does feel a little on the light side. This is the one he handed to me when he told me to put my Spike’s ST-T2 away. It’s 3¼”.
EDIT: BUFFER WEIGHT 3.1-3.2oz

I’m using the buffer spring that came in the LWRC LPK. I believe it’s the chrome silicon flatwire buffer spring. Copper in color and MIL-SPEC I’m guessing.



Do you know anything about the bolt he uses, or what he has to do to it to make it .45 ACP?? Do you have any pics of the bolt?
My research about it has shown that it takes a little more fabrication work than your average AR ‘LEGO’ build (I use that term loosely). The bolt (http://firearmsdesigner.com/?p=378) has to be bored and extractor needs a dremel.

I believe there’s a degree of finesse and experience that is applied during the upper build. The barrels have to be made from blanks considering there isn’t too large of a requesting market. This was a McGowen blank cut to Ron's specs.

I didn’t ask if the blocks were custom or shelf, but they’re not the clamp type. I can see hex screws at the bottom of the gas block securing it to the barrel.

I was concerned about needing to do that for the Glock 21 lower build for the magazines. But for this application, they’re all there. Not much of a ramp was needed, but it is there. I tried getting a good angle of it.

Yep, this is the centerpiece of my collection for the time being.:dance3:

That is a pretty sweet rifle. I like it!

That was a nice writeup! Don't know if I'll ever get around to a .45 carbine build, but if I do you've given me a lot to consider!

Thanks guys. I'd like to try building an upper like that myself someday, but I'll prolly get another upper from him before I even think about heading down that path. So I'll at least have two points of reference...and two functional DI45s.;)

Thanks answering those questions.

Anytime.

Next AR45 that gets put together, I was thinking of integrating this into it.

Passing thought, I'm still unsure.

I was actually thinking of using that upper myself, but it has a couple of extra parts, (note the "slide rail") that only adds to complexity, and a possible failure.
Also you either need to buy their BCG, or have a notch milled into your BCG for it to grab into the side charger handle. (notice the notch cut into the side of the BCG in the 2nd pic, that allows the charger to grab into)
Not to mention, it is very expensive.

I also considered the LAR OPS 4 upper, but don't really like how the side charger will reciprocate with the bolt. Also it has a "plug" that screws into the back, where the charging handle would normally be, to allow you to be able to remove the BCG (plug in 2nd pic);........I can just see that coming lose and getting lost!!!

With all that said, I ended up just getting the VLTOR MUR 1A

Here's a pic of my lower.......I'll post pics of the complete gun, once I get the upper from Ron.

Agreed. But it would be cool to see something different. On the other side of the coin, it would be weird to have a carbine that’s not outdoor friendly. If I did build with it, I’d want to torture test the piss out of it. I found that Spike's Tactical actually used these for their 9mm build before their 9mmV1. I asked them about it and what they thought, and they said that Tom at Spikes just wanted to go another direction.




I also considered the LAR OPS 4 upper, but don't really like how the side charger will reciprocate with the bolt.

I’m not a fan of the reciprocating charger either. Those leave even more access for debris to the receiver. There are other applications that have a side charger (FAL, SCAR, KRISS, R.E.P.R.), but all of which don’t have the bolt as exposed. I also see the side charger having most benefit in prone on a scoped distance getter.

Great choice. I like mine to the point that I might get another.

Nice! Left handed? Is Ron making you a lefty upper? When you shoot, you have to tell me how you like that trigger. I've been eyeing the Mega trigger for a while. Troy latch plate and stock is a nice touch too.

How does one get ahold of Justin at CNC Guns for one of these lowers? I tried to e-mail but can't tell if it made it. Thanks.

Email him with the title "Funds ready to send for lower", and I'm sure he'll get back to you in record time...I'm totally joking.

I'm sure he got your email, he prolly hasn't seen it yet. He is a busy guy. If you're looking for a AR45 lower, he had a few left of his lastest batch a few weeks ago.

Fill out this form (http://www.cncguns.com/downloads/PO/ar45%20purchase%20order.pdf), then email him that you're good-to-go. He'll get back to you.

Thanks, No lefty upper; just a standard VLTOR, so far far from what I can tell, I like the mega trigger; It's easy to install, has a short clean break, and short reset, and it looks bad ass too!!

The Troy latch plate is nice, but I will say it was a pain to install; the bump outs that hold the QD sockets, get in the way of the wrench, making it hard to tighten. As you can probably see from the pic, I'll have no shortage of QD attachment points; as the stock has one on the bottom and one on each side.

The Troy stock is my favorite, especially for an SBR; it's nice and short, has a great cheek well, and the back plate flips down for plenty of storage.

An update----had communications with Justin yesterday. Looking good for an AR45 build at this point for me real soon.

Thanks all.

I just found out that DDLES has officially released their Glock 21 lowers! They refer them as their Glock Large Frame (http://www.shop.doublediamondsupply.com/Custom-Products_c9.htm) since it accommodates 10mm and 45ACP rounds with large designed GLOCK MAGAZINES!

This is definitely next level...I ordered mine already.:dance3:

okay...I think that wraps it up for me in pistol cal carbines for a while. This helped me have some closure with them for the time being...I'll SBR it later...I'd rather build a distance getter now. But here's some details about this build (http://m4carbine.net/showthread.php?p=1663110#post1663110).
