The Griffin Armament HUB HRT-5K AM is a compact, low backpressure 5.56mm suppressor at 4.5″ overall length, adapted from Griffin’s full-size HRT-556 program. It is printed from Nickel 625X alloy with SLM additive manufacturing and uses a 17-4 H900 stainless steel rear.

The industry-standard HUB 1.375×24 threaded rear lets you pick the mount: Griffin HUB mount adapters or other makers’ inserts. It ships without a muzzle device or HUB mount. Griffin lists -34.7dB (137.3dB on a 12.5″ MK2) and 1.50″ from the rear of the HUB interface to the blast baffle. Not user serviceable.
