I have to say, the AR-15 Bolt Carrier Group with the Black Nitride finish has truly exceeded my expectations. It's not just a simple part; it's a game-changer for my AR-15.This Bolt Carrier Group runs smoothly and flawlessly, no matter what I throw at it.
Great except for one flaw
I’ve had this bolt carrier group for sometime now. I’ve got about 500 rounds on it through a carbine length gas system. I’ve had no issues with anything being out of spec or not functioning properly. The only problem I have is 500 rounds in and the BCG doesn’t pass the gas ring test. I don’t know if rise used sub-par gas rings, I have a sample size of one. After changing the gas rings to springco gas rings I had no issues.
Super smooth and durable
Put this in my aero upper and it ran flawlessly. Mag dump and all. Wiped it down after and looked like new still. 10/10
Looks to be of great quality still building my 300 blackout will update review when completed and fired.
Withstands heavy and hard use
I've ran a Rise BCG for several years and thousands of rounds,only part I broke was the extractor , and they squared away immediately.
