ALG Defense AR-10 AR-15 QMS Trigger

This AR-10/AR-15 trigger is smoother than a stock trigger by honing the sear surfaces smooth while not removing metal below the valleys of the stock surface finish. Sear geometry has not been changed from standard so the high reliability that the stock trigger is known for is unchanged. The trigger and hammer are made from true 8620 alloy steel military specification castings, correctly carburized, quenched and tempered for high surface hardness. The disconnector is 1070 high carbon steel properly Austempered into the spring range of hardness. Springs are corrosion resistant and meet military specifications. A full force hammer spring is used for positive ignition of all type of ammunition. Trigger and hammer pins are improved over stock mild steel by using 4140 chrome-moly steel that has been quenched and tempered. Pins are centerless ground to a fine finish and a diameter 0.001” larger than stock to reduce play in the trigger assembly while retaining a slip fit into the weapon lower receiver. Pull weight is above the U.S. Military minimum pull weight of 5.5 pounds but does not reach near the upper limit of 9.5 pounds (generally, the pull weight is about 6.5 pounds). The trigger can be substituted for lower performing stock triggers while still staying in compliance with Unit or Departmental requirements. MADE IN THE USA
