The ALG Defense Advanced
Combat Trigger (ACT) is designed for those shooters where tradition,
value and regulatory concerns are of primary importance. The pull of the
ACT is very similar to a standard mil-spec trigger, however it is
sharper and the grittiness of the stock trigger pull has been removed
while the traditional reliability of a stock trigger remains. The pull
weight is not lower than the M4/M16 minimum weight specification of
5.5lbs.
Note about HardLubing:
HardLubing is ALG's term for electroless Nickel plating with an
integral modifier to the base nickel plate.
Either Boron or Teflon
is used to enhance surface
hardness, wear resistance and corrosion resistance and also create favorable tribological properties of the trigger components.
Testing has shown that differential coating
of the trigger parts contributes to the sharpness of the ACT's single stage
pull. The trigger
component is plated
with Nickel-Boron which has a high surface hardness
combined with excellent wear resistance. The color is a pleasing matte light grey that may be painted on non-functional
surfaces if the shooter so desires (such as the trigger bow that
is visible outside
the lower receiver). The hammer, disconnector and trigger/hammer pins are plated
with Nickel-Teflon which combines
a low coefficient of friction with good wear resistance. The Teflon impregnation colors the metal a mottled, greyish/green. Parts coated with Nickel-Teflon cannot be painted.
Both coatings are highly
corrosion resistant eliminating the oil seal of traditional phosphated firearm
components.
