US12345493 - Tool-less takedown bushing/compensator device for pistol

The patent describes a tool-less takedown bushing/compensator device for semiautomatic pistols, featuring a quarter turn bayonet mount that allows for easy attachment and removal from the slide. It includes a button assembly that, when activated, provides clearance for the device to be rotated from a locked to an unlocked position, facilitating disassembly without tools.

Claim 1

1. For a semiautomatic pistol having a frame, a barrel having a longitudinal axis, a slide having a front end surrounding the barrel, a recoil spring disposed in the slide, a recoil spring plug and a guide rod having a longitudinal axis, a bushing/compensator device for the semiautomatic pistol that provides for tool-less disassembly of the slide from the frame of the pistol, the bushing/compensator device comprising: (a) a compensator member having a front end and a rear end, comprising: (i) a first aperture extending between the front end and the rear end of the compensator member, the first aperture having a front end, a rear end, and a longitudinal axis that is coaxial with the longitudinal axis of the barrel; and (ii) a second aperture extending between the front end and the rear end of the compensator member, the second aperture having front end, a rear end, and a longitudinal axis that is coaxial with the longitudinal axis of the guide rod of the pistol when the bushing/compensator device is mounted on the slide; (b) a quarter turn bayonet mount at a rear end of the first aperture that mates with a bayonet mount aperture in the front end of the slide, wherein when the bayonet mount is in a locked position, the longitudinal axis of the second aperture is aligned with the longitudinal axis of the guide rod of the pistol, and when the bayonet mount is rotated to an unlocked position, the bushing/compensator device is removable from the slide; and (c) a button assembly slidingly retained in the second aperture, the button assembly comprising: (i) a rod having a first end and a second end, the first end having a head, the second end for receipt of a fastener, the rod slidable from a first longitudinal position wherein the head is adjacent to the front end of the second aperture, to a second longitudinal position wherein the second end of the rod depresses the recoil spring plug; and (ii) a spring to bias the rod to the first longitudinal position; whereby, when a user depresses the first end of the rod, the second end of the rod depresses the recoil spring plug providing clearance to provide for the bushing/compensator device to be rotated from the locked position to the unlocked position. (a) a compensator member having a front end and a rear end, comprising: (i) a first aperture extending between the front end and the rear end of the compensator member, the first aperture having a front end, a rear end, and a longitudinal axis that is coaxial with the longitudinal axis of the barrel; and (ii) a second aperture extending between the front end and the rear end of the compensator member, the second aperture having front end, a rear end, and a longitudinal axis that is coaxial with the longitudinal axis of the guide rod of the pistol when the bushing/compensator device is mounted on the slide; (i) a first aperture extending between the front end and the rear end of the compensator member, the first aperture having a front end, a rear end, and a longitudinal axis that is coaxial with the longitudinal axis of the barrel; and (ii) a second aperture extending between the front end and the rear end of the compensator member, the second aperture having front end, a rear end, and a longitudinal axis that is coaxial with the longitudinal axis of the guide rod of the pistol when the bushing/compensator device is mounted on the slide; (b) a quarter turn bayonet mount at a rear end of the first aperture that mates with a bayonet mount aperture in the front end of the slide, wherein when the bayonet mount is in a locked position, the longitudinal axis of the second aperture is aligned with the longitudinal axis of the guide rod of the pistol, and when the bayonet mount is rotated to an unlocked position, the bushing/compensator device is removable from the slide; and (c) a button assembly slidingly retained in the second aperture, the button assembly comprising: (i) a rod having a first end and a second end, the first end having a head, the second end for receipt of a fastener, the rod slidable from a first longitudinal position wherein the head is adjacent to the front end of the second aperture, to a second longitudinal position wherein the second end of the rod depresses the recoil spring plug; and (ii) a spring to bias the rod to the first longitudinal position; (i) a rod having a first end and a second end, the first end having a head, the second end for receipt of a fastener, the rod slidable from a first longitudinal position wherein the head is adjacent to the front end of the second aperture, to a second longitudinal position wherein the second end of the rod depresses the recoil spring plug; and (ii) a spring to bias the rod to the first longitudinal position; whereby, when a user depresses the first end of the rod, the second end of the rod depresses the recoil spring plug providing clearance to provide for the bushing/compensator device to be rotated from the locked position to the unlocked position.
