BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to a cartridge casing catcher with reduced firearm ejection port flash and noise.
2. Background Art
Cartridge casing catchers are mounted adjacent the ejection port of a firearm to catch the spent cartridge casings as the casings are ejected after a round is fired. The spent cartridge casings are generally collected for reloading and to
prevent casings from being underfoot which can cause a shooter or observer unstable shooting or movement. The spent cartridge casings may also be collected by a cartridge casing catcher (and container) to reduce the evidence left at the shooting site
and to reduce the noise generated during the shooting by eliminating the noise generated when the casings impact the surface (i.e., floor, roof, etc.) where the shooter (i.e., firearm user) is positioned. An example of a conventional spent shell
container is shown in U.S. Pat. . . . . More |

A catcher, in combination with a firearm having an ejection port, for
receiving and retaining expended magnetically attracted shell casings
through the ejection port as the firearm is discharged. The catcher
includes a hollow housing having a plurality of rigid walls, and
retainers. One of the walls has an opening in communication with the
ejection port when the catcher is mounted to the firearm for receiving
the shell casings. A seal is attached to the housing at the opening and
surrounding the opening and provides controlled release of pressurized
ejection port gas from inside the housing as the firearm is discharged
such that noise and flash as a result of escape of the pressurized
ejection port gas is reduced or eliminated.

What is claimed is:
1. A catcher, in combination with a firearm having an ejection port, for receiving and retaining expended magnetically attracted shell casings through the ejection port as
the firearm is discharged, the catcher comprising: a hollow housing having a plurality of rigid walls, wherein one of the walls has an opening in communication with the ejection port when the catcher is mounted to the firearm for receiving the shell
casings, at least one of the other walls comprises a plurality of deflectors and each of the deflectors has a front face that is slanted away from the opening such that the deflectors are capable of deflecting the shell casings away from the opening and
a rear face that is perpendicular to the planar surface of the housing or slanted away from the opening, and at least one of the deflectors, alone or in combination with one or more other of the deflectors and a respective wall, comprise a void and an
aperture configured as an acoustic tuner st . . . . More |
