replacement barrels for the M&P 10

[bergermeister]

AERO is good equipment!

Small Holes:

This is the Aero Precision Nickel Boron BCG at Primary arms - their description says its a DPMS patterm BCG. Am I missing something else here?

Aero Precision .308 Complete Bolt Carrier Group - Nickel Boron - APRH100185

Can't confirm your application but I can say that this BCG does fit a DPMS pattern and IS a first-class unit.

While not a barrel replacement, the following is the response I recently got from S&W about the availability of complete uppers in other chamberings.

Thank you for letting us know how you feel about the unavailability of the M&P 10 uppers. Unfortunately, it is a company decision, however I will forward your email to our engineers so they can see that it is frustration to our customers.
Regards, Rachel

Meanwhile, one can get an M&P15 upper just about any where they want....

MP10 Nightmare

Bought new MP10 and gun dealer upgraded barrel to Mega Arms DPMS Clone. Have not been able to shoot since new light strikes or none...Only SW firing pin can be used as it has spring on it and AR pins are much bigger. I'm lost and out of a lot of money as the gun dealer went out of business and now I feel like I do have a frankengun. Anyone who owns a MP 10 does the firing pin not protrude much out of BCG? Mine barely comes out....No one here in CA wants to touch it as they have no experience with MP10....I have also been told by SW that you cannot use a different bolt as it is a different size. Need real help here

My current understanding is that to use a DPMS pattern barrel, you would need to also use a DPMS bolt carrier and bolt assembly. You would also need to check headspacing on the components as the FP protrusion could cause light strikes as well on a loose assembly. I am not sure if DPMS uses a FP spring either, and depending upon ammo, this combo could cause issues, as the original gun was set up for commercial hunting ammo with potentially lighter primers than a mil spec projectile.

Smith & Wesson M&P 10 Upgrade

Originally I posted a horrible experience I had as I thought that my new MP10 could not be upgraded from factory and that I was just stuck with a huge paperweight with worthless expensive upgrades. I am 100% wrong and I think that the main issue was the fact that I was dealing with the wrong gun dealer and the wrong so called armorers that said they knew it all! After much research and I mean a lot of research I have found all of any issues non-existent and I am 120% satisfied with the Smith & Wesson M&P10. I will post pictures soon to show how my build went and I hope that this gives everyone an idea of what to expect with this gun. So yes you can upgrade this gun easily with many mods....One huge suggestion before doing anything to a perfectly made gun right off the shelf is shoot the darn thing and put a lot of rounds in it before you change anything out! I highly recommend this gun and wish that this knowledge was available to me years ago. Smith & Wesson stock is an excellent rifle off the shelf and I am very happy to see how much thought S&W has put into this gun. Happy with my AR's but this one takes the cake. Very solid and clean and well built. No gap issues or noises as it seems this gun is very tight in all aspects. Thanks for any prior posts from people in here to help out with the build. Parts that can be used for your build. Armalite AR10 BCG/DPMS pattern with firing pin and spring similar to the S&W stock BCG, Mega Arms Barrel 16" DPMS, head space not an issue with the parts and perfect, DPMS float handguard, Uber Stock.....Comp was custom tuned to match barrel. Main thing because I am so damn anal, no modifications were done to this gun, such as dremmeling or changing.

I just swapped to an aero bcg and aftermarket barrel. I've only done quick test fire session for operation. Every thing is working good so far will post again after its run hard a few times

Any updates? I'd like to know in the future that I can change out my barrel to a 20in

Hoping for some help.

Based on this thread, pulled my barrel and threw in a Ballistic Advantage 6.5 Creedmoor barrel and an Aero BCG.

Keep getting Feed errors using Gen 2 and 3 Pmags with 140gr American Gunner. The bolt either skims the top of the round and closes empty, or it half picks up the round but jams on the way in the chamber with the point hitting the roof of the barrel extension.

Did you who swapped to 6.5 have to modify your mags to get good feeding?

 

[cclark89]

To add. When chambering a round manually using the CH or bolt release, it picks the round up fine.

Does it lock back on an empty mag on the last shot?

No it was failing to do so.

Now on rifle-length gas.

 

[MistWolf]

Now on rifle-length gas.

Then it is short stroking. Either ammo is not making enough pressure, system is leaking, or gas port diameter is too small. That is assuming that the mag locks back the bolt when the action is manually operated

 

[mcap1655]

The gas port in my M&P 10 was enlarged to 0.077" (was 0.068") to correct an intermittent cycling issues the rifle was experiencing with 7.62 Nato ammo. Have since replaced the gas block with a low profile and haven't had any issues since.

Not very helpful for 6.5 creedmoor but that's my experience...

Thank you. I'm going to double check the gas block and tube alignment. Also make sure the gas rings are staggered. Then run it pretty wet this weekend when I take her out. The rifle really only had a couple hundred rounds through it before the update. May just need to be broken in a little. If it's more of the same then I'll start some more intensive troubleshooting.

 

[MistWolf]

Check the gas key as well.

Don't worry about staggering the ring gaps. It won't hurt anything to do so, but it won't help either
