Irregular Design Group Hesychia Sixk Bundle 5.56/6ARC Suppressor, Black - 1/2x28 HFH

*Includes muzzle device

The Hesychia SIXK suppressor derives its name from Orthodox Christian tradition: Hesychia means “stillness” or “silence,” reflecting a monastic pursuit of tranquility. Unlike the typically aggressive names used for suppressors, this one emphasizes peace. The “SIXK” portion comes from Irregular Design Group’s goal of creating the best compact (“K”/Kurz) suppressor.

The suppressor is made from 718 Inconel via laser powder-bed fusion and features an internal gas-flow system that lowers backpressure while maintaining strong sound and flash suppression. The Hesychia SIXK uses recessed front vents, asymmetric baffles, and a dual-ring (annular) internal design to spin and break up hot gases, greatly reducing its signature. Weighing 15.5 oz. and measuring 1.65" in diameter and 5.125" in added length, it matches or exceeds the performance of comparable suppressors in its size class.
