Features

Advanced Trigger System far superior over the stock trigger system in both performance and durability

Provides smooth cocking, comfort loading, light pull trigger action and highly enhanced stability. Provides the necessary durability for high power operation and upgrades

Integrated modified trigger sear, piston sear and trigger bearing to allow a full range of power upgrades. The Alpha trigger system retains the original safety function.

The Alpha trigger system provides an adjustable trigger sensitivity for advanced shooting requirements and habits. (clock-wise for lighter pull and counter-clockwise for heavier pull. Avoid over-screwing.)

Designed to provide minimal friction for a fast response and light trigger pull under high power upgrade. (The stock trigger box will experience strong tension and friction after high power upgrades.)

The original 45 degree piston design creates unnecessary friction with the Cylinder. The Alpha trigger's second piston sear will catch the integrated 90 degree piston properly to maximize durability and stability.

100% Full CNC Milled Military Grade Aluminum Housing. 100% Full CNC High Carbon Steel (H.C.S.) Internal Sear Set. 100% Full CNC High Carbon Steel (H.C.S.) Trigger.
