Armalite Ar-10 vs M&P Ar-10

Keepin_Jeepin · March 1, 2013, 03:09 AM

So I have an M&P AR-10... wondering how it compares in construction too the Aramalite.

I found this free float tube, I am wondering if it will fit. I think it will, because their construction looks so similar, and I just dont think their site has been upgraded because the M&P is so new..

Having a hard time finding one that is in stock, that doesnt have rails on it. This is perfect and the price is great!

AR-10 is a ArmaLite trade name. Only ArmaLite makes a AR-10, they make the AR-10A and AR-10B, different magazines.

Your "M&P AR-10" is actually called "M&P10" by Smith & Wesson. A new 7.62 on a already crowed 7.62 AR market. S&W has been slow about releasing specs on the M&P10, I don't know what fits it? Is it a DPMS clone?

Model 1 sales has been good with me. I haven't bought that much from them.

DPMS pattern guns use a different barrel nut then Armalite pattern guns. You will need to know what pattern gun the MP10 is and you will want to contact Model 1 Sales to find out what all that FFT will fit.

Personally, I'd stay away from Model1sales.

Do a Google of them to read about their history.

I would recommend you wait until you have hard facts about the barrel fitment of the upper receiver, contact S&W and check if it is DPMS or Armalite compatible. I would contact the specific manufacturer of whatever free float tube you are going to use and find out if it will fit the M&P10. And if you buy one make sure whomever you get it from will take it back if it does not fit.

Okay, great advice thanks guys

Dude, not to be a douche, but when I opened the link it says in red right beneath the item name "For Armalite AR-10 Rifles ONLY".

I'm suspecting this would not fit your M&P, but thats just a guess.

In my first post

"I just dont think their site has been upgraded because the M&P is so new.."

The M&P10 is new this year after the SHOT show. Its modeled after one of the other AR-10s just dont know what one yet.

If its modeled after the armalite it would fit. Maybe its not and their site is accurate still though. IDK

That doesn't say anything about the barrel nut. Being it's a SR-25 mag I would bet it's a KAC pattern (DPMS).

"AR-10" is a particular rifle, not a group of similar rifles.

It's like calling all revolvers Smith&Wesson.

jehu · March 2, 2013, 09:34 AM

It's highly possible that someone else is making that rifle for S&W and they are just putting their name on it. So find out if S&W is making the rifle or if not who is and go from there.

The Long Shot · March 2, 2013, 12:40 PM

You'd need to use SR25 pattern parts not AR-10 pattern parts for your rifle.

blfuller · March 2, 2013, 01:04 PM

It has a mid length gas system as well so that would need to taken into consideration.

Keepin_Jeepin · March 2, 2013, 02:37 PM

So this is what I did last night. Forgive me for not thinking of this sooner, but, partially disassembled one of each. It looks like I might be able to use ar-15 stuff on this.

Please correct me if I am wrong I have never modified either type of these guns. but the handguards at the ends look to be the same. I dont know how a free float tube attaches but from what I saw it looked pretty universal

There are some AR15 parts that interchange with the 7.62 AR platform. Mostly the LPK parts. The barrel nuts on the 7.62 is a larger diameter than the AR15, and while the hand guards may look the same on the outside they well have a different internal size. The barrel nuts are different with the 7.62 platform, ArmaLite or KAC (SR-25) pattern.

**4V50 Gary** · March 3, 2013, 11:16 AM

Changes may be more than handguards.

Hopefully S&W made its M&P AR-10 compatible with AR-15 parts. Same pins, roll pins, trigger, sear, springs, buffer tubes, buffer, buffer spring, bolt & bolt carrier. Ditto with its collapsable stock and all the tools association with working on the AR.

madcratebuilder · March 4, 2013, 11:47 AM

The RE and buffer/spring is a compatibility problem because of the longer bolt carrier for the 7.62. The AR15 RE/stock is useable with the correct length buffer and spring. I don't think you could use the same BCG with both 5.56 and 7.62

As far as I know all 7.62 AR's share AR15 pins/springs/fgc/safety/grip. Most have a proprietary mag release and bolt catch. Initially most used AR15 mag and bolt releases but had reliability issues. Both DPMS and ArmaLite are proprietary, and I assume LMT/KAC are too.
