Product Description The Hiperfire Hipertouch Enhanced Duty Trigger (EDT) 2-Stage is a precision-engineered drop-in trigger assembly designed for AR-15 and AR-10 platforms. Featuring radical sear mechanics for smooth and accurate performance, the EDT 2-Stage delivers a crisp, clean trigger break, a well-defined positive second-stage wall, short over-travel, and a positive reset you can both feel and hear. Two user-selectable hammer springs are included, allowing shooters to fine-tune pull weight to their preference: a Blue Hammer Spring offering a 3.5 lb first stage plus a 1 lb second stage for a total of 4.5 lbs, or a Green Hammer Spring offering a 4.5 lb first stage plus a 1 lb second stage for a total of 5.5 lbs. Built with heavy-duty hammer springs to ensure hard hammer strikes at medium pull weights, this trigger is a significant upgrade over any mil-spec factory trigger. Note: not intended for use in pistol-caliber carbine or blowback applications.
