Irregular Design Group HFH Inconel 718 Hollow Muzzle Device

Irregular Design Group HFH Inconel 718 Hollow Muzzle Device

The Irregular Design Group HFH Hybrid Flash Hider is more than a muzzle device—it’s a precision-engineered Quick Detach (QD) system built to deliver uncompromising performance. Crafted from heat-treated Inconel 718 using advanced LPBF additive manufacturing, this hybrid flash hider is designed to seamlessly integrate with the HESYCHIA SIX Series suppressors while excelling as a standalone solution.

With its patent-pending Hesion Bow dual-locking system, the HFH locks down with over 1,700 lbs. of sealing force in under 2.5 turns, ensuring rock-solid alignment and reliability under extreme heat and shock. Its Hybrid Flash-Recoil Core disperses gas through diamond-shaped ports and helical pathways, cutting flash signature and softening recoil for smoother, more controlled shooting.

Whether paired with a suppressor or running solo, the HFH delivers optimized gas distribution, reduced thermal binding, and unmatched durability. This is the next evolution in muzzle technology—engineered for shooters who demand precision, efficiency, and reliability in every shot.

Aerospace-Grade Alloy
Heat-Treated Inconel 718 resists extreme heat and stress for long-lasting durability.

Hybrid Flash-Recoil Core
Helical structure with diamond ports disperses gas smoothly, reducing flash and recoil.

Hesion Bow Locking System
Patent-pending dual-lock mechanism integrates directly with suppressors for flawless alignment.

Quick Detach (QD) Mount
Achieves full taper lock in under 2.5 turns with just 15 ft-lbs. of torque.

Optimized Gas Control
Vectoring design channels gas to suppressor blast chamber walls for steady, controlled shooting.

Consistent Thermal Expansion
Matching Inconel construction prevents thermal binding and premature wear.

Additive Manufacturing (AM)
Advanced LPBF construction enables precision geometry and robust structural integrity.
