This is my second BCM BCG. First one has been serving me well for a long time.
by Ramiro -
a quality bolt carrier group
by MarkM -
It's not as "slippery" as my other brand bcg, but that BCG caused endless issues at first. This thing seems bomb proof, and I'm pretty sure it cycles every bit as well. Buy these, they just work.
Very nice BCG

Absolutely a great BCG got it for a BCM build can’t go wrong with mil spec from a veteran operated business
BEST BCG FOR YOUR MONEY!
by Christian D. -
Have this BCG in all my ar's and they are all dead nuts reliable. Accept no substitutes, BCM is one of the few companies that I would bet my life on, and I have no qualms using their components in a Duty/or HD rifle. On a side note, major props to Primary Arms, who shipped my stuff the same day I ordered them. That is IMO truly amazing, and PA has just won over a customer. Keep it up!
Top tier MIL-SPEC
by David -
Always a quality BCG, made right the first time. I have purchased several different BCG and BCM is the top tier of the MIL-SPEC world. As far as Primary Arms goes, good prices, and fast shipping. Thanks guys
Made my PSA uppper run properly
by Scott T. -
The most important things about BCM is the precision of their components. They fit right, work right, and are made of genuinely quality materials. My new bcg turned a problem child into a winner (100 rounds running perfectly.) Kudos to Primary Arms for quick shipping. Money well spent.

Great BCG by BCM. Changed out the original BCG that was installed on my PSA AR15. Great upgrade and performance. No issues on extraction. Well made and durable. Will be ordering another one for my AR pistol build. Great shipping and price.

BCM Bolt Carrier

Very nice BCM Bolt Carrier Group and got here in a blink of the eye !!!
Fast delivery!! Best price on bcm bcg
First off primary arms besides bcm itself has super fast delivery ordered Friday mid day and received Monday.for all of 6 bucks to ship fast and reasonable shipping. Excellent bcg well oiled and you just know it's quality when you get your hands on it. Great job primary arms great job bcm!! I wish primary would keep great sales and deals going all the time . I've found a few cheaper companies. But you won't find the bcm bcg cheaper than primary arms so if you can catch it on sale buy it!! Thanks for great price and shipping

Absolutely outstanding. Recently completed build w/ this bcg, aero upper, BCA 16in 1:8 H barrel , RRA lower. Flawless function; excellent accuracy. This is the only bcg I will use in any future builds--can't recommend highly enough.
BCM and PRIMARY ARMS THE BEST COMBINATION FOR QUALITY PRODUCT AND SERVICE THAT UNTOUCHABLE AND THAT A FACT
Best of two worlds
by Matthew -
Absolute perfection. If you stopped by so I could tell you to buy this, you already know what to do. It's not even a question by it, enjoy the satisfaction of making a good decision. As always PA IS FIRST in the business.
Simply the best
by Coach Barry
I have completed two AR builds using the Bravo Company BCGs and am very impressed. Fit finish and function are everything I expected and my next build will definitely contain the same. Combine Bravo Company quality with Primary Arms service and they are both simply the best.
Bought this because of BCM's fanatical QA and reputation for extreme quality. Might be the best BCG on the market. Fits perfect functions perfect will be my choice in any future builds.
Have not installed yet, but looks good, no flaws. Shipping was super fast as always
