ALG Defense Single Stage Quality Mil-Spec (QMS) Trigger for AR-15/LR-308

The ALG Defense Quality Mil-Spec (QMS) trigger is an enhanced Mil-Spec type AR-15 trigger. The QMS is very similar to Mil-Spec units in pull weight, but the honed sear surfaces and polishing result in a smoother than standard pull. The honing of the sear surfaces does not change the geometry of the stock trigger, so the high reliability of the Mil-Spec trigger is maintained. The pull weight falls within the Military specifications of 5.5 to 9.0 pounds. The pull of the ACT is very similar to a standard mil-spec trigger, however it is sharper and the grittiness of the stock trigger pull has been removed while the traditional reliability of a stock trigger remains. The pull weight is not lower than the M4/M16 minimum weight specification of 5.5lbs.

The ALG Defense Quality Mil-Spec (QMS) Trigger is designed for those shooters where tradition, value and regulatory concerns are of primary importance. Tuned by Geissele Automatics.

• 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.
