Best BCG on the market

by -

Best of the best here, fit and finish

Little known fact

by -

Something I have found about these bolt carriers is they have a radius cut in the gas key. This allows the POF roller cam pin to drop right in. Awesome bolt carrier group. I also have one of these with noveske cross. I couldn't be happier.

One of the best available

Pared this BCG with a 13.7 BA Hansen Barrel and it works flawlessly. Very well made BCG and the nitride coating is much easier to clean that phosphate. I will be using RCA from this point forward on my builds.

Fantastic BCG and CS

I picked up this BCG as part of a build for my wife. There was a minor issue first day on the range, but Rubber City customer service answered the call on the first ring, spent a bunch of time with me on the phone, rapidly responded to email correspondence, and helped me determine there was an ID-10t problem on my end. Now that the error has been corrected, this puppy runs reliably and very well. Solid feel to it. I definitely recommend this BCG or any BCG from Rubber City!

The thing comes in a sort of jewelry box and the heavy rubber cover peels back to reveal a work of art. Flawless finish, excellent staking, nitrided firing pin, so smooth I almost hated to get it dirty. I can see why a certain high-end AR manufacturer OEMs from these guys.

Great BCG

Fantastic BCG. The gas key staking was done well, the nitride finish is slick, and it worked flawlessly at the range.

Super Smooth


I’ve had this bcg 2 years now and have shot alil over 700 rounds through it. Nothing crazy at all but the damn thing still looks brand new and is 10 times more smooth running than my phosphate bcg. 10/10
