HUB Adapter

The Hesychia SIXK-H suppressor is designed to work with Hub adaptors. We recommend the Reardon Plan-B system (link) and offer FULL WARRANTY for the Reardon system. WE DO NOT WARRANTY ANY OTHER Hub adaptors for issues due to walkoff or misalignment from MD/adaptor. The first blast baffle has a standoff of 1.64". Warranty does NOT cover Keymo.

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.
