The HESYCHIA series features IDG's revolutionary Hesion Bow system that provides a secure but simple dual locking mechanism through the use of 6 bi-directional locking arms that engage within 32 grooves around the outer edge of the muzzle device paired with a 15-degree taper and American Buttress Thread style mount. The suppressors are also constructed of 718 Inconel alloy ensuring extreme heat resistance and durability. The SIXK is designed for 5.56 and 6mm cartridges and features a 3D printed construction with an emphasis on low backpressure and short length, measuring at only 5.72 inches while adding only 3.6 inches to overall barrel length. This model features a raw inconel color pattern and comes with a Hesion Bow QD muzzle device in a 1/2x28 TPI thread pattern. *Sound reduction ratings are based on average range of 160-166 dB and may vary depending on firearm configuration.*
