Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application claims the benefit of U.S. Provisional Application No. 62/510,707, filed on May 24, 2017, which is incorporated herein by reference in its entirety.
    • FIELD
  • The present invention relates to a firearm. More particularly, the present invention relates to an expansion chamber assembly for a firearm.
    • BACKGROUND
  • Firing a bullet from a firearm creates a loud noise. The firearm silencers known in the art have various baffles and intermediate spacers that attempt to decrease the noise level created by the firearm when firing a bullet. These silencers are heavy, use lots of different types of parts and/or are difficult to assemble thereby making them expensive to manufacture and quite costly for ultimate consumers. In addition, many prior art silencers do not significantly reduce muzzle flash and/or recoil generated by the firearm when firing the bullet. Therefore, a need exists for a way to reduce noise levels, flash and/or recoil when firing a firearm.
