Product Description The Hiperfire EDT Designated Marksman Trigger Assembly is a precision-engineered, single-stage upgrade designed for AR-15 and AR-308 platforms. Built around Hiperfire&';s proven Enhanced Duty Trigger (EDT) design philosophy, this assembly delivers a clean, decisive break, minimal creep, short over-travel, and a fast, audible reset that serious shooters demand. The Designated Marksman variant features Hiperfire&';s exclusive Duplex Trigger Bow, which allows the shooter to place their finger in a high position for a heavier pull and an added measure of safety, or a low position for precise, target-rifle control. Paired with an extra-weight SwingFast Hammer Head for unusually fast lock times, this trigger assembly is ideal for precision shooting, competitive use, and any application where repeatable accuracy and reliable primer ignition are non-negotiable. The self-cleaning design allows debris to fall free, preventing jams and reset issues even in demanding conditions.
