The Irregular Design Group Hesychia 7SIX2 is a next-generation .30 caliber suppressor built by a team with Tier 1 special operations roots, and it shows in every detail. The can is 3D printed as a single monolithic unit from Inconel 718 using Laser Powder Bed Fusion, then precision-machined at its critical interfaces. The result is a sealed, one-piece core with no internal parts to loosen or shift. At just 6.0" long and 16.7 oz, it delivers serious .30 cal suppression in a compact, rugged package, and its low back-pressure design cuts the gas and concussion that reach the shooter.

What truly sets the Hesychia apart is IDG’s patented Hesion Bow Dual-Lock Mount. The primary lock uses a 15-degree taper and a 1 1/8"-8 left-hand buttress thread that seals with modest torque. As a secondary lock, six flexure pawls printed into the suppressor body engage 32 grooves on the muzzle device for built-in redundant retention, a safeguard against a can working loose. This bundle includes IDG’s Micro HFH (Hybrid Flash Hider) in 5/8"-24, the balanced choice for rifles that run both suppressed and unsuppressed, with strong flash control either way. Because the can, mount, and muzzle device are all Inconel 718, they expand at the same rate under heat to help prevent lock-up. Full-auto rated and built for 7.62 NATO and other supersonic .30 cal cartridges, the Hesychia 7SIX2 is a premium, hard-use suppressor built to protect the shooter as much as it quiets the shot.
