M4 HPA Tuneable Trigger - Blade

The SPEED Airsoft M4 HPA Tuneable Triggers are designed to work with HPA conversion systems with MOSFET/microswitch.
The SPEED M4 HPA Tuneable Triggers incorporates dual external adjustment set screws which will enable a trigger pull under 1mm with ease. The SPEED M4 HPA Tuneable Triggers also includes a specially designed coil compression spring that reduces the pull tension, so players with HPA engines can rip lightning fast strings easily even in semi-automatic mode.

Supports TM compatible V2 HPA converted gearboxes. Do not use on Kythera or any other mechanical engines.
