Abstract
Embodiments of the invention relate to a dynamic suppression mechanism for a firearm. Multiple chambers are aligned within a housing, with adjacently positioned chambers separated by a partition. A central aperture is provided within the partition(s) to accommodate the projectile and form part of the projectile path, and multiple relief ports are annularly arranged around the central aperture. As the projectile travels through the path and through the length of the housing, the relief ports use gas byproduct released from the projectile as an elastic medium to muffle concussive forces and mitigate flash as the projectile is released from the body.
Claims18
An apparatus comprising:
- a body defining a housing in communication with a muzzle end of a firearm, the body having a first end and a second end, the first end adaptively secured to a muzzle end of a projectile release device, and the second end oppositely disposed;
- the housing defining a hollow interior surrounding a path along which a projectile can travel;
- the housing comprising:
- two or more sleeves, including a first sleeve having a proximal end and a distal end, the proximal end in communication with the muzzle and the distal end in communication with a proximal end of a first partition, and a second sleeve having a proximal end and a distal end, the proximal end of the second sleeve in communication with a distal end of the first partition, and the distal end of the second sleeve in communication with an exit partition;
- the first partition having a central aperture and a plurality of pressure relief ports axially disposed, the central aperture being a part of the projectile path;
- the exit partition forming the second end of the body, the exit partition having a central aperture being a part of the projectile path, and a plurality of exit partition relief ports axially disposed;
- the exit relief ports being a plurality of apertures that extend from a proximal end of the partition to a distal end of the partition;
- and
- the exit relief ports being tapered with a proximal end of the relief port being adjacent to the proximal end of the exit partition, and a distal end of the relief port being adjacent to the distal end of the exit partition, and the proximal end of the port having a proximal aperture in communication with a distal aperture of the port, including the distal aperture being larger than the proximal aperture.
