Irregular Defense Hesychia 556UK - USED

IRREGULAR DESIGN GROUP HESYCHIA 556UK - FDE - USED

This is a used Irregular Design Group Hesychia 556UK in Flat Dark Earth, a sealed monolithic Inconel 718 suppressor for 5.56 NATO, made by laser powder bed fusion. It uses IDG's Hesion Bow dual-lock mount and comes with a 1/2x28 IDG muzzle device in Flat Dark Earth, so it is ready to mount on a 1/2x28 threaded barrel 10.3" or longer. Capitol Armory does not carry this model new, so specifications are sourced from Irregular Design Group.

USED CONDITION

This Hesychia 556UK comes like new in the box and appears to have never been fired, with no carbon fouling on the inside. It has some handling marks, including a couple of small black scrapes around the mounting system. Images may be generic and may not show this specific suppressor.
