The Hiperfire EDTHG Enhanced Duty Heavy Gunner is a single-stage curved trigger for AR-platform rifles built around one core idea: a lighter, crisper trigger pull without compromising the reliability your rifle needs. This curved-shoe trigger fits small-pin (.153") AR-15 lower receivers and AR-308 rifles that accept AR-15 trigger groups, making it a drop-in upgrade for most modern platform builds. Where a standard mil-spec trigger feels heavy and mushy, the EDTHG delivers a 4.50–5.50 lb pull weight with a smooth, predictable break and fast reset—the kind of trigger that rewards good technique whether you're running a patrol rifle, service match, or defensive setup.

The Heavy Gunner variant steps up from the Sharp Shooter with an even beefier SwingFast hammer designed to guarantee hard, positive primer strikes under any condition. Hiperfire's engineering preserves full mil-spec hammer energy while the refined trigger geometry and lighter pull weight give you genuine shooter feedback—no creep, short over-travel, and a reset you can both feel and hear. The self-cleaning design allows debris to shed cleanly, reducing the risk of jams or reset failures in field use. Two interchangeable hammer springs let you dial in either 4.5 or 5.5 lb draw weight to match your preference and application.

If you run a hard-use AR and want a trigger that splits the difference between competition smoothness and duty reliability, the EDTHG Heavy Gunner does exactly that. It's not a hair-trigger; it's a well-engineered tool that makes your fundamentals matter and your shots count.

Frequently Asked Questions

What AR rifles does the EDTHG trigger fit?

The EDTHG is designed for small-pin (.153") AR-15 lower receivers and AR-308 rifles that use AR-15-type trigger groups. Before purchase, confirm your lower uses the small-pin configuration; large-pin lowers require a different trigger.

How do I adjust the pull weight between 4.5 and 5.5 lbs?

The trigger comes with two interchangeable hammer springs—one for 4.5 lb pull and one for 5.5 lb pull. Swapping them changes the pull weight; no other adjustment is needed.

Is this trigger safe for duty and defensive use?

Yes. The EDTHG is built to mil-spec reliability standards with preserved hammer energy for positive strikes. The Heavy Gunner variant uses an extra-weight SwingFast hammer specifically designed for ultra-reliable ignition in duty, law enforcement, and defensive roles.

What's included in the package?

The EDTHG comes complete with the trigger group, hammer, two interchangeable hammer springs (for 4.5 and 5.5 lb pull weights), and curved trigger shoe.
