The Griffin Armament HUB HRT-556 AM is a 5.56mm suppressor built around an additively manufactured Nickel 625X superalloy core made with SLM technology. Its ultra low backpressure design suits both left-handed and right-handed shooters. The integrated HUB rear thread is 1.375x24 TPI, so you can set it up with Griffin's HUB mount adapters or with other makers' inserts. In Griffin's testing, Nickel 625X showed roughly 68% higher yield and tensile strength than additively manufactured INCONEL 625 at 1200°F, which gives the core strength at high temperature.

A high performance flash hider end cap is built in to help reduce muzzle flash. The printed core is laser-welded to a machined rear, so the suppressor can be serviced if needed. The body is stainless steel with a nickel alloy baffle material and a black finish. Griffin lists minimal POI shift for this model, which helps you hold your accuracy with it mounted.
