The Irregular Design Group Hesychia SIXK + HFH Bundle is a compact, monolithic Inconel 718 rifle suppressor package purpose-built for 6MM ARC and 5.56 NATO. Printed as a single piece via laser powder bed fusion, the Hesychia SIXK uses a radial diamond initial chamber and early annular gas pathways to manage pressure at the source, reducing back pressure without relying solely on traditional baffle stacks. The patent-pending Hesion Bow dual-lock mount integrates a 15-degree taper with 1 1/8"-8 left-hand American Buttress threads and six flexure pawls that engage 32 grooves on the included muzzle device for fast, secure attachment in under 2.5 turns. Measuring 5.72" long, 1.65" in diameter, and weighing 15.5 oz, this suppressor is optimized for hard use on 10.3" and longer barrels while remaining full-auto rated. The bundle includes the Hybrid Flash Hider for balanced performance when shooting both suppressed and unsuppressed, and the raw Inconel finish highlights the intricate exterior geometry seen across the tube. Ideal for range work, training, and general-purpose rifle use where reduced sound and gas blowback are priorities, the Hesychia SIXK reflects Irregular Design Group’s focus on innovative engineering and durable construction.
