If you have some .22 firearms that are factory threaded 1/2 x 20 male, such as the new CZ 452 rifle or maybe an older Intratec TEC22 pistol, this adapter will allow you to shoot our popular .22 LR suppressors as well as our fake suppressors or any other accessory or adapter that is threaded 1/2 x 28 female. The adapters are knurled on the OD for easy on and off threading. They are hot salt blued steel and are manufactured to exacting tolerances on CNC turning centers in one operation to insure exact alignment of the OD and ID threads.  A thread adapter is also included with the adapter to keep your threads in good shape when no using your suppressor.  Get the most use out of your suppressors with our adapter!
