The ALG Defense Quality Mil-Spec Trigger (ALG-QMS) is designed for those shooters where tradition, value and regulatory concerns are of primary importance. The pull of the QMS is very similar to a standard mil-spec trigger, however the majority of the associated grittiness of 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.
Performance
Advantages for the Shooter
• The final
grind operation has a better finish than that of what passes for a stock
mil-spec trigger and results in a much smoother pull.
• 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 retain a slip fit into the weapon's lower receiver.
Advantages
for the Armorer
• The ALG
Defense MS trigger is a standard trigger so maintenance and installation
procedures are unchanged.
• There is
spare parts commonality between the QMS and stock triggers.
• Trigger
assembly parts may be interchanged between triggers, there are no matched sets.
• Since it
is a trigger meeting the U.S. Military trigger specifications for the M4
Carbine, the ALG Defense QMS can be substituted for lower performing stock
triggers while still staying in compliance with Unit or Departmental
requirements.
