Device for modification of ejected casings trajectories

Abstract

A device for modification of ejected casings trajectories includes a top side and a bottom side. The bottom side is configured for attachment to a location on a firearm. The location is in an expected trajectory of spent casings ejected from the firearm. The top side includes a surface facing the expected trajectory of the spent casings. The surface is configured to modify a trajectory of the spent casings by accepting an impact at an angle with each spent casing at a point of impact on the surface and deflecting the spent casings at a deflection angle. The deflection angle is dependent on the point of impact. The surface may include an angled surface or a curved surface. One side of the curved or angled surface may be raised compared to another side of the curved or angled surface.
