Abstract
A coupling for removably mounting accessories on the end of a gun barrel wherein the gun barrel includes at least one lug spaced from the barrel end. A coupling adapter receives the gun barrel end and lugs and includes lug retaining recesses which receive the lugs upon relative rotation between the gun barrel and adapter occurring. A compressible spring located within the adapter biases an annular lug engaging sleeve wherein lug retention within the adapter recesses is maintained by the spring and only an axial movement of the adapter on the gun barrel is required to disengage the lug and its retaining recess to permit rotation of the adapter for quick adapter mounting and removal.
