Abstract
A coupling system attaches a device such as a blank adaptor or a sound suppressor to the flash hider of a firearm. The device is slid over the flash hider until a set of flat surfaces on it are aligned with a set of holes in the device. Camming latches are held in the holes in the device. The collar carried by the device is then threadably advanced to a locking position with respect to the device where it presses the camming latches into secure engagement with the flat surfaces on the flash hider. Unthreading the collar to the unlocked position allows the camming latches to be moved radially when the device is to be removed or rotated. A spring lock prevents the collar from rotating during use, particularly during firing of the firearm but may be released to rotate the collar between locked and unlocked positions.
