The Xeno Brake and Adapter mate together with left-handed threads eliminating worries of the adapter unthreading from the silencer when removed.Both the Brake and Adapter feature ample tooling surfaces giving plenty of room and options. These tool features are accessible even when the suppressor is completely installed. The material is nitrided 4140 steel for hardness and corrosion resistance.
