A QD mount screws into the back of a modular suppressor and lets it lock onto a matching muzzle device. The muzzle device stays on the rifle; the suppressor and mount come off together. You need both halves: this mount and a muzzle device that presents the same interface.
This one locks onto any IDG Hesion Bow muzzle device and threads into suppressors with a HUB 1.375x24 rear.

See all 597 in the Builder- The adapter is not caliber specific.
- Most HUB adapters are just a thread and a shoulder. The Hesion Bow HUB Adapter offers the steepest and longest taper interface on the market while still providing a redundant retention system that has never been applied before on suppressors.
- The Hesion Bow HUB Adapter lets HUB-format suppressors run on the same taper and locking system as the native Hesychia family: it handles the HUB side at the back of the can while the rifle still sees a 15-degree taper and 1.125-8 American buttress thread instead of a loose thread converter.
- Overall length 1.2" at 2.5 oz, with a 0.400" HUB thread length, 1.5" wrench flats, a 1.5" mounting face diameter and a 1.61" projected outer diameter.
- The adapter is a single-piece LPBF Inconel 718 part with flexure pawls built into the body. Those pawls act as springs for active retention, giving clamp force and zero-backlash engagement without external levers or collars to loosen under heat and fouling.
- There is no assembly, no small parts and no dissimilar materials — Inconel 718 throughout the entire system.
- The Hesion Bow HUB Adapter uses Inconel 718 so the muzzle device, suppressor body, and Hesion Bow HUB adapter share the same thermal behavior. When dissimilar alloys are mixed, such as a 17-4 muzzle device driving into an Inconel 718 taper, the faster-growing component can wedge itself into the mating taper, gall the surface, and make the suppressor feel thermally locked once everything cools.
- In testing, the adapter has been cycled on and off more than 3000 times without loss of retention.
- The HUB Adapter uses a coarse 1.125-8 American buttress thread, a profile originally developed for hostile, dirty applications like tank barrels and artillery breech interfaces. The intentionally blunted crest increases impact and galling resistance and leaves a relief path for gas, keeping carbon from compacting in the threads the way it does on fine-pitch, sharp-crested thread systems.
- The Hesion Bow HUB Adapter is compatible with Hesychia SIXK-H and Hesychia 556UK-H suppressors and plugs them into the same Hesion Bow muzzle devices as the native SIXK and 556UK cans.
- The HUB Adapter uses 1.5" wrench flats across the protective hoods and is meant to be torqued into the suppressor and left alone; day to day you mount and remove the can at the Hesion Bow interface on the rifle side, not by spinning the HUB every time.
