Quick Tip: How To Align a Gas Block on an AR-15 Barrel
This YouTube video from Brownells Gun Tech™ features Caleb Savant providing a practical tip for installing a low-profile gas block on an AR-15. The technique focuses on utilizing the setscrew hole on the underside of the gas block and a dimple on the barrel to ensure perfect alignment when gas block manufacturers use that hole for their drilling process. This method is specifically for AR-15s with setscrew-anchored gas blocks and dimpled barrels, simplifying the installation process and guaranteeing precise alignment for optimal gas system function.
