ALG Combat Trigger 05-199 (ACT)

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 HardLubing 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 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. Both pins are Nickel-Teflon
coated.
• 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 6.0lbs.

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 1. Performance Advantages for the Shooter
