The Hiperfire EDT Designated Marksman Trigger (Hiperfire part no. EDTDM) is a single-stage, semi-auto Enhanced Duty Trigger for AR-15 and AR-10 rifles. Hiperfire calls it a significant AR upgrade for military, LE/SWAT and personal use. Its Duplex trigger bow has two positions, so one trigger can be set for a shorter, heavier pull or a longer, lighter one. Break is crisp and clean with very short over-travel. It suits a shooter who wants to choose the pull character instead of living with a fixed bow.

Key Specifications

• The Designated Marksman is a single-stage, semi-auto trigger, with one clean pull from rest to break.
• Hiperfire recommends it for AR-15 and AR-10 variants, so one trigger covers both lower sizes.
• The Duplex trigger bow has two positions, which lets you tune the pull to the rifle.
• The bow’s high position gives a shortened pull and higher weight, which Hiperfire frames as safety under duress.
• The bow’s low position gives a lengthened pull and lower weight, which Hiperfire frames as tactical precision.
• The trigger break is crisp and clean, which keeps shot placement predictable.
• Very short over-travel lets the finger stop almost as soon as the sear releases.
• The reset is positive and audible, so you can feel and hear it for faster follow-up shots.
• Hiperfire builds the trigger for military, LE/SWAT and personal use as a significant AR upgrade, and it is made in the USA.
