Best BCG on the market

Best of the best here, fit and finish
Little known fact
by Robert -
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.
