This tutorial demonstrates how to tune an AR-15 adjustable gas block for optimal reliability. Key steps include starting with the gas block open one turn, incrementally opening it until the bolt locks back on an empty magazine, and then adding a reliability buffer of 0.5 to 1.0 additional turns. Finally, the setting is secured using blue Loctite after recording the adjustment screw's rotation count.
