The MA EDT (Enhanced Duty Trigger) trigger pull is smoother
than a stock trigger. This is accomplished by honing the sear surfaces smooth
while not removing metal below the valleys of the stock surface finish.
Trigger and hammer are made from true 8620 alloy steel
military specification castings, correctly carbonized, quenched and tempered
for high surface hardness.
Disconnector is 1070 High Carbon steel properly tempered
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
center-less 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. Reduced power springs are included, those are
typically 2 – 4lbs lighter.
