Irregular Design Group HESYCHIA SIXK 6mm Inconel Suppressor + HFH Muzzle Device Bundle

HESYCHIA SIXK 6mm Inconel Suppressor + HFH Muzzle Device Bundle

The HESYCHIA SIXK Multi-Stage Hybrid Suppressor represents the cutting edge of suppressor engineering, combining advanced materials, patented locking systems, and a multi-stage hybrid core for unmatched reliability and performance. Printed from Inconel 718 using Laser Powder Bed Fusion (LPBF) additive manufacturing, the SIXK is designed to withstand extreme heat, shock, and full-auto fire while delivering superior sound and flash suppression.

At just 5.72" overall length and weighing 15.5 oz, the SIXK adds only 3.625" to the muzzle, making it compact yet highly effective. Its patent-pending Hesion Bow dual-locking system secures the suppressor with over 1,700 lbs. of sealing force, using a 15-degree taper and American Buttress Thread that locks in under 2.5 turns. Six integral flexure pawls engage a 32-tooth geared ring for sub-degree precision, ensuring absolute reliability under stress.

The multi-stage hybrid core reduces backpressure, noise, and flash while venting gas forward to protect both shooter and firearm. Asymmetric baffles, helical pathways, and recessed flash-hiding geometry maximize turbulence, minimize carbon buildup, and extend off-gassing duration for cleaner, longer-lasting performance.

Paired with the HESYCHIA Hybrid Flash Hider, crafted from matching Inconel 718, the system achieves perfect thermal harmony, eliminating binding and wear. Whether used by professionals or enthusiasts, the SIXK delivers unparalleled efficiency, durability, and confidence in any scenario.

Aerospace-Grade Alloy
Inconel 718 delivers extreme heat resistance and long-term durability under heavy fire.

Multi-Stage Hybrid Core
Reduces backpressure, flash, and sound while optimizing gas flow for cleaner operation.

Hesion Bow Locking System
Patent-pending dual-lock mechanism with six flexure pawls for sub-degree precision and zero failure points.

Optimized Gas Control
3D Printed asymmetric baffles and helical pathways extend off-gassing, minimize carbon buildup, and maximize turbulence.

Flash-Hiding Geometry
Recessed design eliminates snag hazards and filters unburnt powder to cut external flash.

Full Auto Rated
Built to withstand sustained fire without compromise.

Consistent Thermal Expansion
Matching suppressor and flash hider materials prevent binding and premature wear.

Easy Maintenance
Designed for ultrasonic cleaning; performance indicators help identify when service is needed.
