AR15 Bolt Carrier Group Review

You can read some of AR15 Bolt reviews below. They are real customer who purchase this BCG.

By bigtote: This BCG is the best smooth action slides like butter and cleans so easy ! I would definitely recommend this BCG . The finish is flawless , gas rings work perfectly my Ar is much more accurate now n clean up is just wiping it off . Thank WMD gun for selling and making such a high quality part !!!!!

By Pete: This is a terrific NiB Bolt Carrier Group (BCG). WMD has done a superior job. The gas screws are well staked unlike my original M4 bolt (20 yrs old). The bolt slides like glass when pulled and there is significantly less friction. I have not fired my M4 yet with the WMD BCG but I have no doubts about it’s performance. I seldom write reviews but I will this time. You can by this WMD BCG with confidence.

By Chief: Excellent fit & function in both .300BLK and 5.56 builds. Headspacing was right on with 2 different barrel brands. Eases cleaning effort. Have run these dry as test, absolutely no issues or failures running 100+ rounds thru it.

By EX75: I was very pleased and excited about this BCG. Shipping was fast and it sure does work really good in my newly built AR 15. Love it!! I couldn’t be more pleased with it!! Will do business again!

By Sav: I have the WMD M-16 BCG with hammer and since installing it several months ago, I’ve run well-over 900 rounds through it with only a few drops of lube here and there. Sure, it cleans up in seconds, but the main reason I went for Nickel Boron was that it offers a superior lubricious surface and it will run dirty far, far longer than a standard-coated or chrome BCG. It’s a fantastically hard coating, an amazing example of modern metallurgy.

But as I opted for the heavier M-16 BCG, I had to go with a heavier buffer (a Spikes Tactical T2) and a stronger action spring (a Sprinco Blue Spring, and I’m using their “Machine Gunner’s” lube–it’s fantastic stuff!) and I haven’t had a single failure to feed, failure to fire (attributable to the BCG), or failure to extract.

After a few basic upgrades to your AR (Optics, Furniture, [Geissele] Trigger Group–in that order) this is your next MUST HAVE!!

Buy it, buy it now! You won’t regret it.
