ALG Defense Triggers


Performance Advantages For The Shooter
ALG triggers are smooother and sharper than your traditional stock trigger. This is accomplished by polishing the sear surface smooth and Hard-lubing the trigger components. Sear geometry has not been changed from the standard profiles 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 made of 1070 High Carbon steel and is properly austempered into the correct range of hardness.

The springs are corrosion resistant and meet U.S. Military specifications. A full force hammer spring is used for positive ignition of all types of ammunition. The trigger and hammer pins are improved over stock mild steel by using 4140 Chrome-Moly steel that has been quenched and tempered. The diameter is 0.001" larger than stock to reduce play in the trigger assembly while retaining a slip fit into the weapon's lower receiver.

Pull weight is above the U.S. Military minimum pull weight of 5.5 lbs. but does not reach near the upper limit of 9.5 lbs.

Advantages For The Armorer
ALG triggers are enhanced standard triggers, so maintenance and installation procedures are unchanged. Trigger assembly parts may be interchanged between triggers, so there are no matched sets. As a trigger meeting the essential U.S. Military trigger specifications for the M4 Carbine, ALG trggers can be substituted for lower performing stock triggers while still staying in compliance with Unit or Departmental requirements.
