Hiperfire EDT Designated Marksman Trigger, Lightning Bow, 1-Stage, Black

The Hiperfire EDT (Enhanced Duty Trigger) Designated Marksman Trigger with a Lightning Bow, 1-stage, in black (brand part number EDTDM) is a significant AR upgrade built for military, LE/SWAT, and personal-use applications. It’s a single-stage, semi-auto-only trigger patented under multiple US patents, and it’s rated for use in AR-15 and AR-10 variants; Hiperfire does not recommend it for AR-9/PCC variants. The Lightning Bow itself is dual-position: a high position shortens the pull and increases perceived weight for safety under duress, while a low position lengthens the pull and lowers weight for tactical precision. Across both positions, the EDT delivers a crisp, clean trigger break, a very short over-travel, and a positive reset shooters can both feel and hear. Every EDT trigger is made in the USA.
