The Griffin Armament 1.375×24 HUB Direct Thread Adapter (brand part no. DT1375X24-1/2X28) steps a Griffin Bushwhacker, OMEGA, NOMAD, or other 1.375×24 HUB-threaded suppressor down to a 1/2×28 host thread. It’s machined in 17-4 stainless steel and finished in a nitride black coating for corrosion resistance. Wrench flats let a shooter attach or remove it from the suppressor body or the firearm’s muzzle threads without any proprietary tools.
