Replacement cap for all rifile barrel shrouds. This cap has a 1/2"X28 front threaded end for 22LR rifles. This allows you to attach muzzle brakes, suppressors, and other accessories without having to remove your shroud.
Works great, it's nice to be able to add a muzzle device and have the ability to leave the shroud in place. Has both male and female 1/2 x 28 threads.
