Haven't been able to put any rounds down range with this, yet, but here's my initial thoughts:Craftsmanship and finish are great.Properly staked bolts.Felt like it cycled in my rifle more smoothly than my BCM (probably due to finish)Really impressed; can't wait to complete the build that this is intended for. Will update my review after using.

I love rise armament. I have an RA 140 trigger. Now I have an RA Nickel-Boron BCG. Its everything I hoped it would be. It’s smooth, sleek, it adds an aesthetic appeal to my ARP and it also functions really well.

I've never run an RA part in my AR-15s, but this BCG is excellent so far. I've got about 100 rounds through it, so not a ton to make any really scientific analysis, but after that 100 rounds, the BCG still looks brand new. No carbon is sticking to it at all. The nickel boron coating is very slick to the touch, and it only requires bare minimum lube. So far it's running and cycling exactly as I'd expect and then some. All the mil-spec features are there, but this goes beyond mil-spec b/c of the NB coating. The gas key is properly staked and the components are all right where they're supposed to be.
