M&P 10 not DPMS format?

MP-10 is NOT DPMS

I bought an allegedly DPMS 22" 6.5 Ballistic Advantage barrel. It does NOT fit the M&P10 bolt lug pattern. I had to cancel an order for Wilson Combat's super sniper barrels because they told me the M&P10's are proprietary and their barrels wont work/fit. Finding a barrel that is compatible with the M&P10 has so far been impossible. Do I dare look for a compatible BCG or even a bolt head?

Reason enough to pass on the MP-10.. I did my research here on the S&W forum.. I had no intention of replacing the barrel, but I have replaced my BCG. So you are stuck with what you have,, I have an idea that S&W really don't want you messing around with their gun?? but who would really know??

This is a real issue out in the real world,, and the main reason I made a hard pass on the MP-10..

If you want to build your own rifle there are a myriad of possibilities out there. If you plan on easily replacing parts and such, this is something to consider. If I need parts for my S&W AR10, I know Smith & Wesson will be around for a while. I have no wish to “Frankenstein” my “Performance Center” 6.5 creedmoor. It is an excellent AR10. I looked at Aeroprecision for a long while but just found the Smith and Wesson Performance Center 6.5 Creedmoor irresistable. Differerent strokes for different folks! Like Billymagg said, “If the M&P 10 is exactly what you want, buy it, its a great rifle.”
I agree!

As mentioned earlier, there is no MILSPEC for AR10s. There is no standard.

We're spoiled by the AR15 platform (and 1911s) with it's MILSPECs.

But without a MILSPEC, there is no standard.

That's why you can't swap slides from Glock 19 or VP9 to M&P?

With an AR10 you will tied to the OEM to an extent. Just need to roll with it.

successful barrel swap

I did a barrel swap on my M&P-10 several years ago. Bear Creak Arsenal barrel and Toolcraft bolt or maybe BCG don't remember. Everything fit like a glove. Feed it many magazines without a problem. My brother has it now. He's thinking of building up a complete upper based on a low profile DPMS upper. Will post if he is successful.

So my brother tried to put a complete Bear Creek upper on it, the profiles matched perfectly but the pin spacing is a few thousand off. He succeeded in getting the front pin in but the upper would not close fully.

Not exactly sure why we care if the MP10 is "compatible" with a bottom tier rifle.

I own a Panther Arms DPMS AR10 (LR308) made in Minnesota (it's about 15+ years old). I would not classify it as "bottom tier" and not just because I own it. We have plenty of very fine high powered rifles in the inventory capable of MOA accuracy (especially when my son does the trigger work). Our DPMS AR10 may be the most accurate rifle we own and it has been 100% reliable. Fifteen years ago it was not an inexpensive rig.

We broke it in according to the manufacturer's instructions, which takes a reasonably long day. The results, which may be coincidental for all I know, were stunning.

It does not get shot much, or at least carried much, as it's on the weighty side. I thought Garands were heavy.
