The invention relates to devices for attaching or removing a sound suppressor or other auxiliary device to a firearm. The device has a mount body threadedly attachable to a muzzle attachment device attached to the muzzle of a gun. A locking spring extends around a portion of the mount body, and has serrated pawls for engaging a portion of the muzzle attachment device. An annular, rotatable locking collar attaches to the mount body and extends over the locking spring. As the locking collar is rotated, a reduction in diameter of the inner surface of the locking collar can urge the pawl into secured contact with the muzzle attachment device.
