The IDG HESYCHIA SIXK + HFH BUNDLE includes our flagship suppressor and muzzle device, everything you need to start shooting suppressed.
HESYCHIA SIXK: Multi-Stage Hybrid Suppressor
Hesion Bow (Patent Pending) Locking System
A patent-pending dual-locking mechanism forged from Inconel 718. Secures with over 1,700 lbs. of sealing force via a 15-degree taper and 1 1/8” - 8 left-hand buttress thread—locks in under 2.5 turns. Six flexure pawls, printed directly into the suppressor body, engage a 32-tooth geared ring for sub-degree precision and zero failure points. The protective hood doubles as 1.5" wrench flats (flat-to-flat) for practical field use. Built for unyielding reliability under heat and shock.
Multi-Stage Hybrid Core
Engineered for control, this core reduces backpressure, noise, and flash while venting gas forward to protect shooter and firearm. Asymmetric baffles maximize harmonic disruption and gas diversion, paired with internal helical annular pathways that extend off-gassing duration from the blast chamber and main stack. Recessed flash-hiding geometry eliminates snag hazards, with special tines filtering unburnt powder to cut external flash. Disruptive micro-texturing on internal gas paths boosts turbulence without fouling.

HESYCHIA Hybrid Flash Hider
Hesion Bow (Patent Pending) Locking System
Additively manufactured from Inconel 718, this hybrid flash hider mates seamlessly with the HESYCHIA SIX Series. Secures with over 1,700 lbs. of sealing force via a 15-degree taper and 1 1/8” - 8 left-hand American Buttress Thread (Patent Pending) —locks tight with just 15 ft-lbs. of torque in under 2.5 turns. Integrates with six flexure pawls in the suppressor for precise alignment and rock-solid hold, no extra parts to fail. Matching Inconel construction and robust thread design resist thermal locking for reliable performance.
Hybrid Flash-Recoil Core
Engineered for balance, this design reduces flash and softens recoil. A helical structure with diamond-shaped ports and subtle baffles disperses gas smoothly, shrinking muzzle signature and disturbance range over traditional hiders. Delivers noticeable recoil reduction standalone, yet shines suppressed—vectoring gas to the SIXK’s blast chamber walls for controlled, steady shooting.
