Abstract:
A safety device for redirecting spent ammunition cartridge cases away from a rifleman or bystander as they are ejected from the ejector port of a semiautomatic or automatic rifle. In a first embodiment, the center mounted embodiment is preferred. The presented device includes a mounting clamp assembly, mounting rod and pivoting deflector. The deflector can be pivoted to permit the ejection pattern desired by the rifleman. In a second embodiment, the side mounted assembly, the mounting clamp assembly is attached to the right hand side rail of the forearm and barrel assembly. In the third embodiment, rear mounted assembly, the clamp mounting assembly is installed at the rear of the upper receiver rail. In a fourth embodiment, forward mounted assembly, the mounting clamp assembly is mounted on the forearm upper accessory mounting rail. All embodiments described herein apply to a left-handed version of the rifle.

Claim (Index 1):
A universal ambidextrous spent ammunition cartridge case deflector that is attachable to any position of an upper receiver rail of a rifle, said rail extending longitudinally from a rear end to a front end, said rifle having a spent ammunition cartridge case ejector port disposed below said rail and on the right or left side of the rifle, comprising: a round mounting rail that extends longitudinally from a rear end to a front end; a mounting block means attached to the round mounting rail for mounting the deflector to said receiver rail; a deflector for downward deflection of spent ammunition cartridge cases as they are ejected out of the ejector port when the rifle is being fired, said deflector plate having left and right side surfaces bounded by rear and front edges joined by top and bottom edges; a pivot means attached to the mounting rail, whereby the deflector plate is adjustably attached to the mounting rail for movement.
