The ALG Defense Quality Mil-Spec Trigger (QMS) is designed for those shooters where tradition, value and regulatory concerns are of primary importance. Lower Parts Kit includes 3.5LB JP Rifles Fire Control Spring Set. This combination of the ALG Trigger and JP Rifles Spring set provides a light, Smooth Trigger Pull with Minimal Trigger Creep.
Performance Advantages for the Shooter
The ALG Defense QMS trigger pull is smoother than a stock trigger. This is accomplished 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.
Trigger and hammer are made from true 8620 alloy steel military specification castings, correctly carburized, quenched and tempered for high surface hardness.
Disconnector is 1070 High Carbon steel properly Austempered into the spring range of hardness
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.
