ALG Defense Mil-Spec Trigger For AR 15

The ALG Defense Quality Mil-Spec (QMS) Trigger is designed for shooters who prioritize tradition, value, and regulatory concerns. The pull of the QMS is very similar to a standard mil-spec trigger; the majority of the grittiness associated with 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.

Features

• Single Stage
• Stock Trigger Reliability
• Smoother Pull than Stock Triggers
• 6.5LB Pull

1. 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 to a smooth finish without removing metal below the valleys of the stock surface finish.
• Sear geometry has not been changed from the standard, so the high reliability of the stock trigger remains unchanged.
• The 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 types of ammunition.
• Trigger and hammer pins are improved over stock mild steel by using 4140 Chrome-Moly steel, 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.

2. Advantages for the Armorer

• The ALG Defense QMS trigger is an enhanced standard trigger, so maintenance and installation procedures are unchanged.
• There is a commonality of spare parts between the QMS and stock triggers
• Trigger assembly parts may be interchanged between triggers; there are no matched sets.
• Since it meets the U.S. Military trigger specifications for the M4 Carbine, the ALG Defense QMS can be substituted for lower-performing stock triggers while still in compliance with Unit or Departmental requirements.
