The Irregular Design Group Hesychia SIXK + HFH Bundle brings a purpose-built rifle suppressor package to shooters who demand low back pressure and rugged durability. This monolithic Inconel 718 can is additively manufactured as a single piece, using a radial diamond initial chamber and early annular gas pathways to manage pressure at the source rather than relying only on traditional baffle stacks. Paired with the included Hybrid Flash Hider, it delivers balanced performance for both 6MM ARC and 5.56 NATO hosts while maintaining a compact 5.72" overall length and 15.5 oz weight. At the heart of the system is Irregular Design Group’s patent-pending Hesion Bow dual-lock mount, combining a 15-degree taper with 1 1/8"-8 left-hand American Buttress threads and six integrally printed flexure pawls that engage 32 grooves on the muzzle device. This design provides fast, repeatable attachment in fewer than 2.5 rotations with secure retention under hard use. Full-auto rated for 10.3" barrels and longer and reporting 139 dB at the ear and 143 dB at the muzzle with no host tuning required, the Hesychia SIXK is well suited for training, range work, and general-purpose rifle use, reflecting Irregular Design Group’s focus on innovation and real-world performance.
