HIPERFIRE Enhanced Duty Trigger Designated Marksman AR15/10 Assembly Semi Auto. The Hipertouch name is short for HIgh Performance TOUCH and EDT for Enhanced Duty Trigger. The EDT3 features a duplex or two-position trigger bow. Place the finger high in the curve and the pull weight is approximately 5 or 6 lbs with the supplied red hammer spring installed. Or with the finger riding low on the vertical tip the weight is approximately 4 or 5 lbs. when the supplied green hammer spring is installed. This trigger is directed to DMR use. Run the finger high in tactical situations or run it low in longer range precision scenarios. It's also appropriate for home defense and hunting applications as the trigger weight is higher than the 24 series triggers. It's the "AR" Fire-Control Group upgrade we've all dreamed of.

A helpful read of the FCG Trouble Shooting Guide relates some issues customers will have during and after installation that are easily resolved with attention to detail and common sense. Hipertouch FCGs may not work in lowers with FCG holes that are outside MIL-Spec toleranced dimensions.
