The ALG Defense Quality Mil-Spec (QMS) Trigger is designed for those shooters where tradition, value and regulatory  concerns are of primary importance. The pull of the QMS is very similar to a standard mil-spec trigger, however the  majority of the associated grittiness of the stock trigger pull has been removed while the well known reliability of a stock  trigger remains. The pull weight is not lower than the M4/M16 minimum weight specification of 5.5lbs.
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.

 • 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 5.5lbs but does not reach near the upper limit of 
9.5lbs. Generally, the pull weight is about 6.5lbs.
