Which BCG are you running?
This video guides viewers through selecting an AR-15 Bolt Carrier Group (BCG) by presenting three options: basic black nitride, smoother nickel boron, and the innovative CAC BCG with downward gas venting. The downward venting design is highlighted for its ability to reduce gas blowback into the shooter's face, especially when using a suppressor, and its potential synergy with gas-venting charging handles.
