Built with a .30 caliber bore and 1/2-28 threads, it is CNC machined from durable 17-4 PH stainless steel with critical alignment features machined in a single setup. It is also designed to work with common .900"-24 suppressor mounting systems such as the Q Plan-B and Rearden MFG Atlas, and includes a 13/16" rear hex for straightforward installation and removal.
