The Violent Etek 5 trigger has an added set screw for micro switch adjustment. This will allow you to rake the trigger forward and fine tune the micro switch activation accordingly.

This trigger is made of Delrin so it is super lightweight and very responsive. The front face of the trigger has a nice radius that runs down the full length of the trigger. The radius on the front gives you a nice feel and contact point with your fingers, not a flat front and corner edge like other triggers on the market.
