Brownells 75th Anniversary - A Shooting Heritage

Lets You Adjust Gas Output For Reliable Extraction/Ejection

Steel gas block lets you adjust the amount of gas flow, so you can tune gas output for reliable extraction and ejection with different ammo types. Brass friction screw holds adjustments without thread locker and won’t mar the adjustment screw. Fits under free-float handguards on .750" O.D. barrels. Dual bottom screws secure block to barrel. Requires Allen wrench, not included.
