Description

The Advanced Combat Trigger (ACT) is a shop favorite. We dig it so much we put them in all ORW-15’s.

1. Performance Advantages for the Shooter
• The ALG Defense ACT trigger pull is smoother and sharper than a stock trigger. This is accomplished by polishing the sear surfaces smooth and Hard Lubing the trigger components.
• Sear geometry has not been changed from the standard profile 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 types 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 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. Generally, the pull weight is about 6.0 lbs.

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