  • Gun noise and recoil suppressor
    Patent number: 6302009
    Abstract: A noise and recoil suppressor that is intended to be mounted within the terminal portion of a firearm barrel. The suppressor is a unitary structure having a cylindrical body and a plurality of chambers extending transversely therethrough and spaced-apart in the longitudinal direction of the device. The chambers are configured so as to restrain and slow the passage of the exhausting gases resulting from a bullet that has discharged and passing therethrough so as to suppress both the resulting noise and recoil from the discharging firearm. The suppressor is provided with external threads adjacent its outer end, and a firearm barrel into which the device is to be slidably inserted is suitably drilled-out and provided with internal threads for threadable securement of the device within the end of a firearm barrel. A second and shorter embodiment of the suppressor is disclosed that primarily functions as a recoil suppressor.
