ALG Defense ACT Advanced Combat Trigger

Description

ALG Defense Advanced Combat Trigger (ACT)

The ALG Defense Advanced Combat Trigger (ACT) is designed for 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 maintaining traditional reliability.

The pull weight is not lower than the M4/M16 minimum specification of 5.5 lbs, and
typically averages around 6.0 lbs.

HardLubing Technology

HardLubing is ALG’s term for electroless Nickel plating with an integral modifier such as
Boron or Teflon. This enhances surface hardness, wear resistance, corrosion resistance,
and improves overall performance of trigger components.

• Trigger Component: Nickel-Boron coated for high surface hardness and wear resistance
  (matte light grey finish).
• Hammer, Disconnector, Pins: Nickel-Teflon coated for low friction and durability
  (greyish/green finish).
• Highly corrosion resistant, eliminating the need for oil sealing.

1. Performance Advantages for the Shooter

• Smoother and sharper trigger pull compared to stock triggers.
• Polished sear surfaces combined with HardLubing technology.
• Maintains standard sear geometry for proven reliability.
• Trigger and hammer made from 8620 alloy steel, properly heat-treated for durability.
• Disconnector made from 1070 high carbon steel, austempered for optimal hardness.
• Corrosion-resistant springs meeting military specifications.
• Full-force hammer spring ensures reliable ignition.
• Trigger and hammer pins made from 4140 Chrome-Moly steel, precision-ground and slightly
  oversized for reduced play.
• Nickel-Teflon coated pins for enhanced performance.
• Pull weight maintained above military minimum (5.5 lbs) but below upper limit (9.5 lbs),
  typically around 6.0 lbs.

2. Advantages for the Armorer

• No changes to standard maintenance and installation procedures.
• Trigger parts are interchangeable; no matched sets required.
• Fully compliant with U.S. Military specifications for M4 Carbine triggers.
• Can replace lower-performing stock triggers while maintaining compliance with
  unit or departmental requirements.
