A firearm slide is disclosed. The firearm may include a slide and a flash hider integrally formed into an end of the slide.

An improved barrel clamp assembly for a multi-barreled minigun includes a barrel clamp tube having a front end, a rear end, and a plurality of longitudinal openings extending between the front end and the rear end. An impeller is mounted in the barrel clamp tube between the tube front end and the tube rear end. The impeller includes a plurality of impeller blades that are spaced around a periphery of the impeller and that project forward from a rear flange portion of the impeller and the impeller blades define a plurality of air channels. A barrel assembly includes the barrel clamp tube, a flash suppressor mounted to the front end of the barrel clamp tube, and a barrel clamp co liar mounted to the rear end of the barrel clamp tube. The impeller is mounted to the barrel clamp tube between the flash suppressor and the barrel clamp collar.

The method of the current invention provides means to maximize firearm suppressor efficiency with regards to maximizing sound attenuation while minimizing physical size and weight and minimizing firearm backpressure and manufacturing cost. In the preferred embodiment, the device consists of a closed cylinder within which is a separate closed inner cylinder of a lesser diameter and length. Holes coaxial with the assembly provide a means to attach the device to the firearm muzzle at the proximal planar end of the device, for the projectile and ejection mass to enter the proximal end of the inner cylinder and for the projectile and ejection mass to exit the device at the distal end of the device.

A suppressor for a firearm includes a baffle stack having an outer surface, the baffle stack comprising a plurality of baffles that define an inner chamber coaxially aligned with a central axis of the baffle stack and a projectile pathway through the baffle stack along the central axis. An outer housing is around the baffle stack and has an inner surface separated from and confronting the outer surface of the baffle stack. An outer chamber is defined between the inner surface of the outer housing and the outer surface of the baffle stack. Flow-directing structures are in the outer chamber. An end cap is connected to a distal end of the outer housing and defines a central opening aligned with the central axis.

Embodiments described herein relate to a suppressor that includes a unitary structure comprising a body having an interior volume and a cone shaped nozzle disposed at one end of the body, wherein the body includes a plurality of cooling channels spanning a length of the body, and a plurality of internal channels that are formed radially inward of the cooling channels, and both of the plurality of cooling channels and the plurality of internal channels terminating in a faceplate of the body, a central bore is formed from a breech end of the body to the faceplate, and a plurality of baffles surround the central bore.

A system for attaching an accessory to a firearm includes a muzzle device configured for attachment to the muzzle end of the firearm, the muzzle device having a first coarse-threaded engagement means and one of an annular grooved surface and a grooved surface engagement mechanism, and an adapter device. The adapter device includes an adapter having a forward portion including an accessory engagement means for receiving the accessory and a rearward portion having a second coarse-threaded engagement means formed on an inner surface of the adapter, a biasing mechanism received on the rearward portion, and a retainer ring received on the rearward portion adjacent to the biasing mechanism, the retainer ring having the other of the annular grooved surface and the grooved surface engagement mechanism. The male coarse-threaded engagement means and the female coarse-threaded engagement means cooperate to releasably secure the adapter device to the muzzle device.
