Looks awesome. Are they at Brownell's yet?

No, these are currently direct only. You can now go to www.magpul.com and purchase your Magpul carbine stock of choice and top-quality Mil-Spec style stock completion components to finish your lower receiver build.
Pretty clear that when they supported A5 tubes on their stocks that this might also be coming. They're also selling springs and buffers, but as of the email that just went out, I'm not seeing A5 buffers just yet.
$50 for the AR15 / M4 tube
https://www.magpul.com/products/magpul-enhanced-receiver-extension-ar15-m4
$60 for an SR25 / A5 tube
https://www.magpul.com/products/magpul-enhanced-receiver-extension-sr25-m110
Not 100% sure how I feel about the 10-position A5 tube. But all the same, this is a big win for A5 buffer systems imo.
Very nice.
Any plans for a5 spec buffers?

That was my first thought as well.
I'm totally pumped about it.
What signifies that this is like the VLTOR A5? Is it that seventh notch? Is this like the VLTOR RE-A5 that is "Receiver is designed to use the VLTOR A5 spring and buffer kit only"

An SR-25 tube on an AR15 is "A5". You need a rifle spring and an A5 buffer with it.
Most people will just buy the "AR15" version. But for those in the know... They'll buy the Magpul SR-15 tube, and use the correct A5 buffer and spring on their AR15. When VLTOR "invented" the A5 system, they were already using a "standardized" tube length from the Armalite AR-10 and KAC SR-25. So TECHNICALLY, others have been making A5 tubes as well, but Magpul listing it as A5-compatible in their material shows that the system is gaining ground (imo).
Beyond helpful - thanks a bunch.

I'll second this one. A Magpul A5 (well, several weights) would be a nice addition.
I'm also on the edge of my seat for when MP decides to do some more lowers. ;-)
Very nice.

I'd also like this see this if its possible. Always good to have another option for high quality buffers/springs/tubes though.

Agreed, they do look well made.
I like the 7 position M4 tubes. It seems like a lot of time when shooting prone, I wish I had just a wee bit more adjustment. These should do nicely.

I've been buying Bcm tubes with the Vltor Kit separate. The Bcm kits ship with an a5ho instead of an a5h2. I guess it's good to have a 3rd option. If the buffers where more plentiful and cheaper that would be good!!
Correct me if I'm wrong, Magpul, but the SR 25/ AR10 RE would be the same length as the A5 RE?
I believe they are setting themselves up quite nicely to slowly take over the entire AR15 market.

I'm not sure the reason why but I would agree with you 3 years ago but now,,, there's not one piece of magpul kit on my 3 ar rifles. Never had any issues and I'm not sure what it is , but that's the pattern oven been in. Either way this is a nice addition to there catalog.

They could make them just fine, the only issue is as I recall would be the spring inside the first weight on the real A5 buffers, patent issue maybe? Aside from that it's 100% a normal buffer stretched .75" or so.

Magpul stuff still rocks man, MOE SL & K2+ grips all day. They're constantly innovating. Ironically, I own absolutely zero BCM products, their stuff is allegedly supposed to be great but I simply prefer other products.

Any plans for a receiver extension for the MOE rifle stock I just bought? Probably not, since they're just a simple tube, but being in CA limits one's options and a number of us are going featureless as of 1/1/2017 with the new AW ban (no collapsible stocks, for example, at least to avoid registration).

After reading the stupidity on the Magpul FB about these, it is nice to see good responses on M4C. Golf clap to the members here.

The MIAD with the notched front strap and largest backstrap is the only thing I can use now. After getting my first one and setting it up that way I like it so much every other AR grip feels very wrong to me now.
UBR is my favorite stock too and by a long shot. I know the weight bothers some people but most guns end up so front heavy (especially with a suppressor) anything to bring some weight rearward is good in my book. Balance is more important to me than a few ounces.
A really lightweight, completely basic gun sure is fun to shoot from time to time though.
This seems like a very logical product for Magpul to start offering. Now you can package this with a stock if you're looking to go with the longer buffer or from commercial to milspec.
Any idea when these will be available at our local gun store?

I kinda agree with you, when I first started building it had to be Magpul or nothing at all. Now, not so much, but I still do have a few items such as the MBUS Pros, and the K2 grips on all my rifles.
And now I really wanna try these out. One thing that could be said of Magpul is when they make a product they make it damn well, wrenches, MBUS pros, these receivers Extensions. Although they aren't in the same demand in my eyes that they once were, you can't deny the quality.
I wouldn't hesitate to say that they are way better when they are making aluminum/metal products then the polymer that made their name. (Not that the polymer product are slacking in anyway).

Yes. See my earlier post in this thread. The unique part about the A5 system is NOT the tube.

What were they saying? TOS level crap?
Do these have numbers on the top of the tube?
More options from quality manufacturers equals a win for people that care about using quality parts. Magpul is a company that I like to support and I do support for some things. Their stocks and grips never did it for me, but they keep doing what they do very well, and keep bringing new products to market. Magpul is definitely comprised of smart, business-minded individuals and is a great asset to us and the firearm industry as a whole.
Yes. See my earlier post in this thread. The unique part about the A5 system is NOT the tube.
Yeah, I got confused between the two different threads.
I'm pretty sure Vltor holds a patent on their buffers. I've got a pile of A5 buffers though...:D

Worse. Wanting numbers on the RE so you "know what hole you're in" type shit.

At the end of the day, unless you're swapping from armor to slick all the time, do you really adjust your stock enough to need to know the position anyway? I set mine and leave em by and large...

For those transporting their rifle to the range, classes, etc. on a constant basis, I can see where having some kind of marking would make things easier at a glance. But of course, that's nothing a silver sharpie dot won't fix.

Man I wish I would have thought of the Sharpie idea before I used my metal number stamps to mark mine, now the bolt gets stuck to the rear at least twice a magazine.

I mark mine with a paint pen to speed things up when I have to collapse it for transport in a bag. 'One mark Vasily, one mark'

15$ is beyond trivial if a build is going to ultimately cost over 2,000. I know I prefer 6 pos RE to 4....the 6 position have a notch close to closed that is ideal for me and 4 pos do not.
Oh man do these look awesome! I guess it's time to sell the other kidney!
Now if they'd just build the ACR...... Sorry.....that was a little bit below the belt...

More positions, and 7075 is enough reason to try it.
Just because things currently are good doesn't mean people shouldn't try to innovate and make stuff better.
Battle arms development, and forward control designs are perfect examples of that, nothing they make is a "new" product, they just make better products out of old ideas. Doesn't mean we should completely ignore the products that get released because the old just do the job? Mil spec pivot pins are fine but everyone of my rifles ditched them for the EPS without a second thought after I first tried them.
Being stagnant benefits no one.
Agreed. The old man, old idea mindset isn't good for the industry at all.
Timing is right on these.
Vltor (as of today) has ZERO stock on any A5 products, and Midway is no longer accepting backorders for A5 products.
Seems like a suspicious coincidence? Or should I take off my tinfoil hat?
Even if it's no improvement over the Vltor stuff, if anything it will be nice to have a reliable supply of easy to find A5 parts.

Same. I buy the BCM tube and rifle spring then pick the buffer of choice. Hard to find but last one I picked up was an A5H3.

You can't even buy a tube (any flavor) from Vltor now.
I'm really curious to compare the SR-25/ A5 version to the KAC SR-25 RE. This may end up a reduced cost option.

The KAC tube is excellent, but as an alternative this tube will interchange with it. Internally, it is the same length.

I didn't say it's useless, or that $15 is an exorbitant price hike...
I am aware of that. I'm specifically looking into smaller details like detent placement and drainage holes, plus a few other minor items.
Take off your tin foil. There is nothing going on.
1. We are less than 80 days from the elections. There is an upsurge already happening.
2. There has been a shortage of A5 stuff for months.

On one of my complete Noveske rifle I have a Magpul CTR that still wiggles when locked. On my other Noveske it locks up tight. It's good to know when purchasing a buffer extension from them it is pretty much guaranteed to be in spec.

Of course I could've...but its not a big deal to me, just saying that with so many "mil spec" buffer extensions out there you never really know what you get. With Magpul making their own there is much less chance of any fitment issues with Magpul stocks.
These were on the 2016 poster cage number 1LX50 which was released months ago.

Yes. The SR-25 uses an AR-10 pattern carbine receiver extension. Use an AR-15 H3 carbine buffer (the longer AR10 pattern receiver extension allows the use of AR-15 carbine sized buffers) and an AR-10 action spring (part # EA1095).
LMT MWS, VLTOR A5 (7-pos), and POF P308 (7-pos) receiver extensions are other AR-10 pattern extensions I like using.
My Magpul rifle extension (10 position) arrived today. I had already procured BCM's version.
-BCM weighed 4.0oz, and the Magpul weighs 4.3oz.
-The Magpul appears to have a dry-film type coating inside. The BCM does not.
-The Magpul, as seen below, appears to be machined much more smoothly inside.
I am sure they will both perform their intended purposes, but the Magpul is likely to have less "scritching" noises.

WS6, Do you have STR to try on the Magpul tube? Do you have more pics to show the outside of the rube with comparison to BCM. I had a chance to receive a 10-position tube which I believe should be Magpul but the logo is removed so I am not 100% sure (but on the market there are only two vendors manufacture 10-posiiton tubes as far as I know). I tried it with STR stock and STR is not able to collapse all the way to the castle nut and lock at the first position. However, for ACS-L, it can lock at the fist position. Seems that STR is not long enough to lock to the first position.
I have an A5 tube to compare, the first position on magpul tube is slightly towards the thread end than the A5 tube. On A5 tube, both STR and ACS-L can lock to the first position.

Someone ground off the MagPul logo? Who else makes a 10 position A5 RE?
I have an STR on a BCM A5 RE, it collapses fully to the castle nut but locks into the second position rather than the first with a total of 7 locking positions.

AR10 spring: $6
End plate + castle nut: $30
Nice setup. If STR only locks into the second position on BCM then it is same for Magpul. STR can collapses fully to the castle nut on Magpul but cannot lock at that position.
WS6, Do you have STR to try on the Magpul tube? Do you have more pics to show the outside of the rube with comparison to BCM. I had a chance to receive a 10-position tube which I believe should be Magpul but the logo is removed so I am not 100% sure (but on the market there are only two vendors manufacture 10-posiiton tubes as far as I know). I tried it with STR stock and STR is not able to collapse all the way to the castle nut and lock at the first position. However, for ACS-L, it can lock at the fist position. Seems that STR is not long enough to lock to the first position.
I have an A5 tube to compare, the first position on magpul tube is slightly towards the thread end than the A5 tube. On A5 tube, both STR and ACS-L can lock to the first position.
I have an MOE S/L and a SOPMOD by Bravo.

WS6, can you please try Magpul SL on the magpul tube? SL is supposedly made for A5. SOPMOD is shorter and according this picture, there's still space between the stock and castle nut when fully collapsed on BCM 8-position.

According to the same thread, the first and last hole on the Vltor and BCM A5 tube is at the the same location. WS6, can you please compare the first and last hole on the Magpul and BCM A5? Thanks. I know for my version 10-postion tube, the last hole is the same as Vltor A5, but the first hole is slightly towards the thread end, which causes STR not able to lock at that position.

Any word on when these will be pushed out to retailers?

Anyone compare/contrast this to the BCM and Vltor? Another thread?
Yes, the front and rear of the adjustment track have open ends instead of being closed. Spent my own money to get some answers, BCM is the best A5 tube, here's why..
Comparing the 4 different a5 tubes, 6 pos vltor, 7 pos vltor, 8 pos bcm, and 10 pos magpul..
The 7, 8, and 10 position tubes all have the same 1st position hole. The 6 pos 1st position matches the bcm 2nd position. If you compare the 7 and 10 to these other tubes, their 2nd position hole is further back, resulting in a longer LOP.
If you have a carbine stock, like magpul SL-K or BCM gunfighter, they will collapse to the 2nd positon on the 7, 8, and 10 tubes. A magpul SL, STR, or vltor imod will collapse to the 1st position on 7, 8, and 10.
In short, bcm has intelligently placed the 2nd position hole on their 8 pos tube to allow the lowest LOP using a carbine stock while maintaining the 1st position for longer stocks. Why vltor did not use this to begin with is a mystery to me.
FYI, magpul SL is the same lop as bcm gunfighter on any of the a5 tubes, except the 6 position. The difference between the magpul and bcm 2nd position holes is very small, the magpul tube is definitely a better choice than a vltor 7 position. The vltor 6 position is still a fine choice if you only use short carbine stocks.
On another note!!! Bcm gunfighter is shorter lop than magpul SLK, unless you remove the butt pad, then magpul takes it by a hair. I love the bcm stock and a5 tube, seems like BCM really figured this stuff out.

FWIW
I ordered one of the SR25/M110 REs back when they first were released. A bit expensive going through the Magpul e-store, but I wanted to try one. The RE looked great, a quality part that you'd expect from Magpul. The only issue I noticed was that the threads on the RE seemed to be a little on the fat side as there was more resistance than normal threading it into the lower receiver, and the end plate barely fit over the threads. The RE, end plate, and castle nut all cam from Magpul.
Both were more of a close fit that I am used to, but they went together w/o issue.
Fast forward to last month when I decided to order two more sets of REs, end plates, and castle nuts. I go to start assembling and I encounter an issue, I've never had before. The end plate will not fit over the threads of the RE. I get about 2 or 3 threads in and it is a no-go without going 'bubba' and getting the hammer out to force it on. both REs and end plates are like this. I contact Magpul C.S. who put me through to technical support. I told them my issue, and basic assessment that either the O.D. is too large, or the end plate I.D. is too small, or out of round. I was asked to take photos and e-mail the technical support line with a description and photos, which I did. I received a reply the following week from tech support stating that replacements would be sent out.
I received two new sets of the same parts after about a week of waiting. Unfortunately they had the exact same problem as the first set. So much for an isolated issue, and for checking things before they go out the door. I decided to try and troubleshoot the issue myself with the parts that I had on hand. I checked the Magpul RE with a Vltor end plate and it fit no problem. Based on this I mistakenly assumed that the issue must be bad Magpul end plates, so I ordered some replacements in an attempt to get the REs installed. Oops the mil-spec end plates didn't fit either. Totally frustrated by this point, I've given up on the Magpul REs. They were all sent back to Magpul. Hopefully they get this kink worked out, but there is, or at least was a mfg. problem somewhere along the line. Might explain why they have not pushed these out to retailers as of yet.
I had no issues with mine.
They were mounted to an Armalite AR-10A.

I have run into this issue with Vltor A5 receiver extentsions paired with some Impact Weapon Components QD end-plates, many are quite tight but a little lube and wiggling did it and a heat gun on the end-plate can help.
I'm not sure the reason why but I would agree with you 3 years ago but now,,, there's not one piece of magpul kit on my 3 ar rifles. Never had any issues and I'm not sure what it is , but that's the pattern oven been in. Either way this is a nice addition to there catalog.
Yeah, I don't use that much Magpul either. Out of eight ARs I have maybe 3 Magpul stocks and 4 MOE+ grips. I use their Pmags, but I have just as many USGI, and a several Lancer mags that work very well.
Magpul stuff still rocks man, MOE SL & K2+ grips all day. They're constantly innovating. Ironically, I own absolutely zero BCM products, their stuff is allegedly supposed to be great but I simply prefer other products.
These two quote above ^ are examples of why there won't be domination by any single company, even Magpul. Right now Magpul doesn't make many metal parts for an AR, and even though these receiver extensions look nice there is really nothing super innovative about them. They are simply mil-spec REs and a copy of the A5 with more holes for adjustments. Coating? LMT has been putting a smooth slick coating on their tubes for a long time.
Also, I'm a little contrary on the A5 too. With a middy 14.5 or 16 inch rifle the A5 seems unnecessary as far as I can tell (my limited experience with my A5 equipped rifle vs. an identical rifle with carbine RE). And probably not necessary with properly gassed carbines that size. The A5 seems like it would be useful for those who want the maximum range of operation in bad conditions with the widest range of ammunition. This is a fine reason for an A5, but few will ever need it.
I was prepared to change out several rifles to A5, but I just have not experienced ANY improved performance with the A5. For information purposes...I ended up going Vltor A5 tube, Sprinco Green, and A5H3 buffer. The identical rifle is LMT Carbine RE, Sprinco Blue, with H2 buffer. Both Noveske N4 barrels and BCM BCGs.
The A5 would be good for an SBR I think.

Would you be as satisfied with a combination that operates in a narrower span of operation compared to a wider span of operation?
Would you be as satisfied with a combination with a reduction in durability than a system with increased durability?
Nothing personal, just questions.

Tom, you didn't know? IT'S THE NEW THING!
Having too much reliability, shootability, and breadth of operation is a complete waste and should be avoided. Plus, one will save $20-ish in the process.
You need to get hip to the square, dude. ;)

I'm taking the A5 plunge and going to see if it smooths out my 11.5 BCM (suppressed and unsuppressed).
Right now it has a Blue Springco and H3, runs both ways with Prvi M193 and Federal SOST, but if the A5 can smooth it out a bit more, I'll be a happy man.
I've tried carbine REs, rifle REs and pistol REs. I've tried carbine buffers, H buffers, H2 buffers, rifle buffers and the buffer that came with the A5. I've tried the LMT Enhanced carrier. In the end, the one item that has the greatest affect in getting an AR to shoot smoothly, is the adjustable gas block. It's all about the gas flow
I would tend towards proper porting of a base barrel for a desired combination than an excessively ported one restricted down to work similarly.
That would be ideal if you know what the optimal port size is for the chosen barrel length and gas system length is, if you know if the rifle will be suppressed or unsuppressed and if the rifle is going to be suppressed, what the optimal gas port is for the combination of barrel length, gas system length and back pressure generated by the particular model of suppressor to be used.
An adjustable gas block is useful if the shooter ports the barrel for unsuppressed use now and decides to add a suppressor later.
All that aside, after experimenting with different ways to tune an AR, what has given the best results is controlling gas flow and the easiest way to control the gas flow is the adjustable gas block
Some do actually collect that trending data to reference.
I prefer dedicated non suppressed or dedicated suppressed porting. The suppressed porting can vary some, but still preferred over a base port being larger than it needs to be to begin with.
Depending on the combination, you can add action mass and other items when adding a can later with some benefits over the H2/A5H2 baseline, there are some cons, but MRBS isn't one of them, depending on the combo.
I'm not sure about this reference to tuning, a good baseline does not need to be anything other than it is for it's own intent parameters for overall function. If changes are made to that, then you need to make sure that changes in timing do not create a deficiency in the system.

Did you ever pick up the ARMS 41B?

No Sir, not yet, I have to call A.R.M.S and order over the phone, they stop selling them online due to people getting the wrong one and returning them.
Once I do, will still need to get my .308 barrel to ADCO to get it mounted.
Windham sent me an email I just found, back in December for their 13" hand guard, stating they have some in stock, but I need to call them as well to order one.
Good grief, first the holidays, and now the tax man cometh, so you know what is happening there, the projects just hit a stopping point....Booo
