The Irregular Design Group Hesychia 556UK + Micro Flow Enhancer Bundle is a compact, dedicated 5.56 NATO suppressor system built as a single monolithic piece of Inconel 718. Designed by USSOF veterans, this ultra-short 4.75" can uses Irregular Design Group’s asymmetric multi-stage gas management to keep tone, flash, and shooter comfort in balance while staying remarkably light at just 13 ounces. The patent-pending Hesion Bow dual-lock mount integrates directly with the included Micro Flow Enhancer muzzle device for fast, repeatable attachment and secure retention under hard use. Purpose-built for the 5.56 platform, the Hesychia 556UK is full-auto rated on 10.3" barrels and longer, delivering measured sound levels of 135 dB at the ear and 138 dB at the muzzle. Its short overall length and 1.75" diameter make it well suited for duty rifles, training carbines, and range-focused builds where maneuverability and balance matter. Shooters looking for a durable, modern suppressor system will appreciate Irregular Design Group’s engineering-focused approach and attention to detail.
