A system for connecting an accessory to a firearm having an enlarged muzzle portion has a body with a bore sized to closely receive the enlarged portion. The body has a stop to limit the insertion depth of the muzzle. A gate is received by the body for movement along the path perpendicular to the bore axis. The gate has a recessed area sized to receive the enlarged muzzle portion. A spring generates axial force to retain the muzzle portion within the recessed area. Compression of the spring enables movement of the gate to shift between an open and closed position, so that the accessory may be removed or installed when in the open position, and secured when in the closed position.

The invention claimed is: 1. A facility for connection to a firearm with a muzzle extending to define a forward direction, the muzzle having an enlarged end portion having a first diameter larger than a second diameter corresponding to a barrel portion adjacent to the enlarged end portion, the facility comprising: a body having an axis; the body having a bore centered on the axis; the body having a gate passage; a gate element received in the gate passage for movement along a gate path perpendicular to the axis; the gate element being operable for movement between a closed position preventing extraction of the end portion from the bore and an open position enabling extraction of the end portion from the bore; the gate element being a planar body having a first face and an opposed second face; the gate element having spaced apart arms with free ends defining a gap therebetween; the gap having a width smaller than the first diameter and larger than the second diameter, such that the barrel portion may pass through the gap, and at least a portion of the enlarged end portion may not pass through the gap; the first face defining a recessed area sized to receive a rear portion of the enlarged end portion of the muzzle when the gate element is in the closed position; the recessed area defining a recess plane below the first face, the recessed area being bounded by a shoulder; the gate element having opposed shoulder portions, each positioned at a free end of the gate element, each protruding above the recess plane, and spaced apart by a distance less than the first diameter, such that the shoulder portions are operable to engage the enlarged end portion to prevent movement of the gate element to the open position, when a rear portion of the enlarged end portion of the muzzle is received in the recessed area. 2. The facility of claim 1 wherein the first face faces the forward direction. 3. The facility of claim 1 wherein the body includes a spring biasing element that biases the body in the forward direction. 4. The facility of claim 1 wherein the body includes an inner sleeve defining a bore, and a spring biasing the inner sleeve in the rearward direction. 5. The facility of claim 4 wherein the inner sleeve includes a stop operable to engage the end portion, such that the body may be biased rearwardly when the muzzle end portion is received in the inner sleeve to enable movement of the gate element to the closed position. 6. The facility of claim 1 wherein the bore of the body closely receives at least a portion of the enlarged end portion of the muzzle. 7. The facility of claim 1 wherein the gate element has a U-shaped profile defining a channel. 8. The facility of claim 7 wherein the channel has a base portion concentric with the axis. 9. The facility of claim 1 wherein the recessed area is defined by an accurate boundary centered on the axis and having a diameter sized to closely receive the rear end portion of the enlarged end portion. 10. The facility of claim 1 wherein the boundary of the recessed area encompasses at least a major portion of the rear portion of the enlarged end portion of the muzzle, when the rear portion is received in the recessed area. 11. The facility of claim 1 wherein the body includes a functional device having a bullet passage, the functional device selected from the group of devices including sound suppressors, flash suppressors, muzzle breaks, adapters, and launching apparatus. 12. A method of removably securing a device to a firearm muzzle having an enlarged end portion with a free end extending in a forward direction, the muzzle having an enlarged end portion having a first diameter larger than a second diameter corresponding to a barrel portion adjacent to the enlarged end portion, comprising the steps: providing a body having a bore sized to closely receive the end portion; providing a movable gate received by the body; the gate being operable for movement between a closed position preventing extraction of the end portion from the bore and an open position enabling extraction of the end portion from the bore; the gate being a planar body having a first face and an opposed second face; the gate having spaced apart arms with free ends defining a gap therebetween; the gap having a width smaller than the first diameter and larger than the second diameter, such that the barrel portion may pass through the gap, and at least a portion of the enlarged end portion may not pass through the gap; the first face defining a recessed area sized to receive a rear portion of the enlarged end portion of the muzzle when the gate is in the closed position; the recessed area defining a recess plane below the first face, the recessed area being bounded by a shoulder; the gate having opposed shoulder portions, each positioned at a free end of the gate element, each protruding above the recess plane, and spaced apart by a distance less than the first diameter; shifting the gate into the open position; inserting the end portion into the bore; moving the body in a rearward direction until the rear portion of the enlarged end portion of the muzzle is positioned in front of the forward face of the movable gate; shifting the gate into the closed position rearward of the enlarged end portion; and releasing the body to engage the gate to the end portion, such that the gate is secured in the closed position. 13. The method of claim 12 further compromising providing a providing a spring and wherein the step of moving the body in a rearward direction includes moving against a spring biasing force of the spring. 14. The method of claim 12 wherein the body includes a stop, and wherein the step of releasing the body includes compressing the end portion between the stop and the gate. 15. The method of claim 12 wherein the steps of shifting the gate into the open position and shifting the gate into the closed position includes sliding the gate in a direction perpendicular to the rearward direction. 16. The method of claim 15 further comprising providing a providing a spring and wherein the step of moving the body to the rearward position includes applying force against a spring biasing force of the spring. 17. The method of claim 12 including removing the device by the step of moving the body in the rearward direction to a rearward position, and shifting the gate from the closed position to the open position while the body is in the rearward position. 18. A facility for connection to a firearm having an enlarged cylinder at the muzzle of a barrel, the enlarged cylinder having a first diameter larger than a second diameter corresponding to a barrel portion adjacent to the enlarged cylinder, the facility comprising: a body defining a bore sized to closely receive the cylinder; the body having a stop associated with the bore to limit the insertion depth of the cylinder; a gate received by the body for movement along the path perpendicular to an axis defined by the bore; the gate being operable for movement between a closed position preventing extraction of the cylinder from the bore and an open position enabling extraction of the cylinder from the bore; the gate being a planar body having a first face and an opposed second face; the gate element having spaced apart arms with free ends defining a gap therebetween; the gap having a width smaller than the first diameter and larger than the second diameter, such that the barrel portion may pass through the gap, and at least a portion of the cylinder may not pass through the gap; the gate defining a recessed area sized to receive a rear portion of the cylinder; and a spring biasing element operable to generate compressive axial force between the gate and the stop, upon the cylinder.
