Quick Tip: Why a "Properly Staked" Gas Key Is Mission Critical
This video from Brownells Gun Tech™ explains the critical importance of a properly staked gas key on an AR-15's bolt carrier group. Caleb Savant details how gas pressure cycles the action and why loose gas key screws, caused by insufficient staking, will lead to gas leaks. This prevents proper bolt carrier cycling, rendering the rifle inoperable. The video emphasizes that proper staking is essential for reliable function, whether for recreational shooting, duty use, or personal defense.
