Product Overview
The Hesychia SIXK suppressor is designed to work with the HFH muzzle device.
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 that 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 both the 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.
