Which AR-10?

[sbbieshelt]

I would like some info on AR-10's. currently looking at the Armalite A10 A4, DPMS LRT, M&P 10. I have built a few AR's but I have heard magazines and other parts are not standard.

edit or should I just build a .300 blackout for one of my current lowers? I currently have a remington 700 in .308 but that's the only .308 I have.

Thanks,

Steve

They aren't standard in that an upper from one Mfg. will not fit the lower of another. Rising in popularity is the DPMS/KAC SR25 platform, same Mags and barrel. Aramalite -A is DPMS platform, -B is proprietary. The M&P 10 gets rated well. Some of the DPMS have an extruded upper that I am not a fan of. I am building a Black Rain AR 10 that I am very happy with so far.

You can always get a .300 blackout upper, the AR10 is probably on someone's to be banned list. .300 blackout ballistics do not come near .308 Win, especially out 200 yards plus.

How about a LWRC?

Your welcome to run a few rounds out of my Armalite Ar-10. It is a proprietary system that requires use of their magazines and DPMS uppers will not work on it.

OK, I understand that the uppers and lowers are not standard but from what i have been reading the other parts are interchangeable, as far as LPK's, Tubes, Buffers, Barrels, etc.... I'm thinking of trying to build myself a AR-10 in .243

Those parts are interchangeable except for the barrel. Because the DPMS platform has the most traction it is easiest to stick with this platform. Armalite AR-10B is proprietary, Armalite AR-10A is DPMS platform. Rock River has their own proprietary platform as well.

LPK is standard AR 15 except for a few parts, they come kitted for .308. Buffer tube is AR15, Buffer spring and buffer are .308 specific.

I have a ColT LE 901-16S. Uses LR25 magazines and with the included adapter, you can put an M4 style 223 or 300 BLK upper on it.

If you can, stop by a local shop that has multiple AR10 platforms in stock. That'll give you a chance to look them over in person. I know 2A Sales has DPMS, Armalite, and Sig Sauer's 716 in stock.

I got my Ruger SR762 at 2A, it was nice to be able to compare a few different ones before you decide... plus you can also ask questions when you are there to decide which is best for you as well...

Also picked up a Black Rain Ordnance matched Billet upper/lower set for .308 from them as well, plan on building it into a precision .308 soon...

Have definitely enjoyed my purchase... lots of fun...just find the one that works best for you...

There is also the Sig 716 Patrol - a piston operated SR25 pattern rifle similar in many ways to the Ruger SR762

2A had one of those in stock the last time I was there last week...

Looked at the Sig when I bought the Ruger...the Sig was nice...just liked the Ruger more...to each his own...they are both great rifles...both would serve well...

Which 7.62 AR platform is the most friendly in interchangeability (mags, uppers, etc.)?

Unless they changed their policy, they won't sell OBRs to MD anymore, even ones in 7.62x51.

 

[TxAggie]

If you're building your own, I highly recommend either Black Rain Ordinance or Mega Arms for you Upper/Lower combo.

If you can't find them, the DPMS is still a good choice.

2A sales has AR-10 specific build kits from DPMS that look like good buys.

That sucks. Im glad I got my order in.

We have a Black Rain that we purchased as a complete rifle from Gun Shack in Mt. Airy. We also have a DPMS.

Nearly all (except Armalite) accept the same PMAG LR series mags. FCG is common with AR-15. Other stuff varies by mfr - some will interchange between brands of lowers and uppers, but many do not.
