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.

a quality bolt carrier group

Solid BCG

by -

This is my second BCM BCG. First one has been serving me well for a long time.

An industry standard for a reason.

by -

BCM knows what they're doing. This BCG is inspected, tested, and guaranteed by a company that stands behind products held to a standard above milspec.

As a side note, I've seen people complaining about the rough texture of the carrier. Phosphate is a porous finish, meaning it ABSORBS lube, carbon, and solvents. Soak your BCG with quality lube/solvent, like you're supposed to, rub it in, and the coarse texture will smooth out, by design.

Function is excellent, Finish is appalling.

As a whole, this BCG is works flawlessly, and that is the important part. Tight tolerances, and excellent over all function.

That being said, there are SEVERE tooling marks inside and out. Fortunately, not on any surfaces absolutely crucial to function, but for the price and reputation of BCM, I expected much better attention to detail. I can't stress it enough, EVERY noncrucial surface is ridiculously wavy.

Every corner and edge of the carrier is extremely sharp as well, and it's leaving excessive wear marks on the buffer and interior of the URG.

For a nearly $180 BCG, I can't recommend it. Go for a Sons of Liberty, or a Sionics BCG. Much greater attention to detail, while still maintaining excellent tolerances, at a lower price too.

Just buy it , you wont regret

Great upgrade , the quality exceeds my expectations , i will use bcm in my future builds

Typical BCM

by -

Not really much to say - it's typical BCM quality, which is excellent. I think you do pay extra for the BCM branding, but this went into a rifle I was building as a gift for my son, everything else is BCM too (except the Spikes lower) and I wanted everything to match. As far as bolt carrier groups, BCM and Toolcraft are my go-to choices.

Best BCG for the money

by -

This is the best BCG for the money. There are more exotic and expensive BCG’s out there, but this is the best mil-spec one available and that’s all you need. Don’t fall for gimmicks and waste your money. BCM loves it’s customers and not just the Government ones. Buy with confidence! My only gripe is that Primary Arms only lets you buy one at a time!!

BCM top quality

by -

I'm going to put this BMC BCG in all my builds going forward. It's a top quality product just like you'd expect from BCM. It's hard not to fan boy over BCM due to their over the top quality, durability and reliability. Wish other companies followed in BCMs path.

Shot great
