ALG Defense QMS Quality Mil-Spec Trigger

The ALG Defense QMS Quality Mil-Spec Trigger is a top-quality trigger designed for shooters who prioritize tradition, value, and regulatory compliance. This trigger offers a smooth pull similar to a standard mil-spec trigger but eliminates the gritty feel often associated with stock triggers while maintaining their renowned reliability. With a pull weight that meets the minimum specification of 5.5lbs for M4/M16 rifles, this trigger is both consistent and dependable.

One of the main advantages for shooters is the improved performance provided by the ALG Defense QMS trigger. The sear surfaces of this trigger are honed smooth without removing metal, resulting in a smoother trigger pull compared to stock triggers. The sear geometry remains unchanged, ensuring the high reliability that stock triggers are known for. The trigger and hammer are made from true 8620 alloy steel military specification castings, carburized, quenched, and tempered for exceptional surface hardness. The disconnector is made of 1070 High Carbon steel, properly Austempered for optimal hardness. All springs are corrosion resistant and meet military specifications. Additionally, a full force hammer spring is included for positive ignition of various types of ammunition. The trigger and hammer pins are made of 4140 Chrome-Moly steel, quenched, tempered, and centerless ground to reduce play in the trigger assembly.

The ALG Defense QMS trigger's pull weight is above the U.S. Military minimum requirement of 5.5lbs but does not reach the upper limit of 9.5lbs. Typically, the pull weight for this trigger is around 6.5lbs. Furthermore, the advantages for armorers are significant. Installation and maintenance procedures remain unchanged, as the QMS trigger is an enhanced version of the standard trigger. There is spare parts commonality between the QMS and stock triggers, allowing for convenient replacements. The trigger assembly parts are interchangeable between triggers, eliminating the need for matched sets. Additionally, the ALG Defense QMS trigger compliantly replaces lower-performing stock triggers, meeting Unit or Departmental requirements while still delivering superior performance.

If you value tradition, affordability, and regulatory adherence, the ALG Defense QMS Quality Mil-Spec Trigger is the ideal choice. With its improved performance and high-quality construction, this trigger is a reliable and compliant upgrade for your firearm.
