Overview

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.

CLEANING SCHEDULE

No matter what anyone claims, silencers need to be cleaned periodically to avoid particulate build up and optimize performance. Here are a few ways you can tell if it is time to clean it:

 

Weight Increase and Cleaning: To monitor carbon buildup, weigh your suppressor when it’s new and record its baseline weight. After around 3,000 rounds, you’ll typically notice significant accumulation. An increase of 2 ounces or more is a strong indicator it’s time for cleaning. Use an ultrasonic bath with a 50/50 mix of water and Simple Green for best results. Cleaners with heaters work better, as the heat helps break down carbon more effectively than room-temperature solutions. Depending on the cleaner’s power and tank size, 15-20 minutes of hot ultrasonic cleaning should suffice. For heavy buildup, multiple cycles may be required. If so, fire a few rounds through the suppressor between cycles—this helps loosen the carbon, allowing the cleaning solution to penetrate deeper.
 
Performance Indicators: More than weight alone, pay attention to changes in performance. If the suppressor feels heavier and you notice increased backpressure, reduced sound suppression, or a shift in point of impact, it’s likely time to clean. Carbon buildup can clog baffles, reducing efficiency.
