The 1.375x24 HUB Direct Thread Adapter provides a direct thread interface for the Griffin Bushwhacker, OMEGA, NOMAD, & other 1.375x24 threaded suppressors. Wrench flats make it equally simple to attach or remove from the suppressor tube body or firearm's muzzle threads. No proprietary tools required. Available in 1/2x28 and 5/8x24. It is important to remember that each host firearm must be checked for baffle alignment via visual inspection before firing.
