A suppressor for a gun

A suppressor for a firearm comprising:

• a blast chamber;
• an inner chamber through which a projectile fired by the firearm passes, and an outer chamber parallel to the inner chamber, wherein blast chamber provides an entry chamber common to both the inner and outer parallel flow paths and the outer chamber provides a gases flow path parallel to the inner chamber in a forward direction and including without a counter-flow flow path,
• wherein the inner chamber comprises one or more baffles to work gases produced by firing the firearm to direct the gases radial outwards of a projectile passageway through the inner chamber, and
• wherein the suppressor is configured so that pressure between the inner chamber and the outer chamber is balanced along the length of the inner and outer chambers so that gases exhaust from the inner and outer chambers at substantially the same time.

A suppressor for a firearm comprising:

• a fitting for attaching the suppressor to a barrel of a firearm at or towards an inlet end of the suppressor, the fitting providing an inlet to the suppressor,
• an end wall at an exit end of the suppressor, the end wall comprising an outlet and at least one gases outlet aperture, the outlet aligned with the inlet to form a projectile pathway for a projectile to pass through the suppressor,
• a tubular side wall extending between the exit end and the inlet end defining an outer shell,
• a blast chamber within the outer shell adjacent the inlet end,
• a tubular inner wall defining an inner chamber and an outer chamber within the shell,
• the inner chamber providing a gases inner flow path for gases to flow in a forward direction from the blast chamber to the outlet,
• the outer chamber providing a gases outer flow path for gases to flow in the forward direction from the blast chamber to the at least one gases outlet aperture, the outer flow path parallel to the inner flow path,
• wherein the outer chamber is without a counter-flow gases flow path in an opposite rearward direction between the blast chamber and the at least one gases outlet, and
• equalisation holes in the tubular inner wall to allow gases flow from the inner flow path to the parallel outer flow path as gases created by firing the firearm flow and/or expand through the suppressor from the blast chamber to the outlet via the inner flow path and the at least one gases outlet aperture via the parallel outer flow path.
