A sound suppressor assembly for use in providing a means to maximize firearm suppressor efficiency with regards to maximizing sound attenuation while minimizing physical size and weight and minimizing firearm backpressure and manufacturing costs. A sound suppressor assembly comprising a closed inner cylinder that is received within a separate outer cylinder having a substantially larger diameter and substantially longer length than said inner cylinder. A sound suppressor assembly comprising a plurality of apertures, or openings, that are coaxially aligned within the assembly, thus providing a means to attach said sound suppressor assembly to a firearm muzzle at a proximal planar end of the present invention, for a bullet and ejection mass to enter a proximal end of said inner cylinder and for said bullet and ejection mass to exit through a distal end of said sound suppressor assembly of the present invention.

The present disclosure presents a barrel assembly for a firearm. The barrel assembly includes a barrel having an internal bore and an external surface, and a recoil spring lug affixed to an outside surface of the barrel. The barrel assembly also includes a slide moveably mounted relative to the barrel, and a recoil spring biased on the recoil spring lug and the slide.

A muzzle adaptation system facilitates the attachment of adaptors to the muzzle of a firearm. A converter is attached to the muzzle of a firearm using existing features such as threads. The adaptors are secured to the converter by a release device that allows the adaptor to be attached without precise alignment or fasteners.

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 muzzle brake has body having a muzzle end and an exit end with at least one side connecting the ends. A muzzle aperture in the muzzle end is sized and configured to fit a firearm muzzle. A projectile aperture in the exit end extends to the muzzle aperture. A line segment within the space of the muzzle aperture aligns with the centerline of the firearm and defines a projectile line through the body. Apertures pass through the body with their generating lines being perpendicular to the projectile line. The apertures are shaped to allow more gases to escape in one direction and to contain gases in the opposing direction. This causes the gases to exert forces on the muzzle brake which compensates for the tendency of the muzzle to rise when the firearm is fired.

A muzzle brake for use with a firearm such as a muzzle-loading firearm, and including at least one access port in the muzzle brake that is large enough (for example at least about 0.5″ or more minimum dimension) for access by a user's fingertip to remove a cleaning patch from the muzzle brake. One or more vent ports that are relatively smaller than the access port may also be provided in the muzzle brake.
