Speed AirsoftHPA M4 Externally Tunable Curved Trigger

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