US12546551 - Muzzle assembly for a firearm

A muzzle device for a firearm may include a device body and a plurality of ball bearings. The device body may be configured to be removably secured to a mount body of a mount configured to be secured to a barrel of the firearm, the mount body including a plurality of lugs each extending radially outward relative to a longitudinal axis of the mount and including a stop and a detent. The device body may include a plurality of protrusions each extending radially inward relative to a longitudinal axis of the muzzle device and configured to engage the stop of a respective lug of the mount to prevent rotation of the muzzle device relative to the mount in a first direction. The ball bearings each may be configured to move relative to the device body and to engage the detent of a respective lug of the mount to inhibit rotation of the muzzle device relative to the mount in a second direction opposite the first direction.
