Abstract
A device is movably attachable to an upper receiver of a firearm adjacent to a rear end of an ejection port on the upper receiver. The device is configured to move linearly in directions parallel to a longitudinal axis of the upper receiver to function as a forward assist to cause a bolt carrier of the firearm to move forward with respect to the upper receiver. The device comprises a shell deflector having a deflection surface configured to deflect spent casings ejected out of the ejection port when the firearm is in operation.
Claims18
An apparatus implementable on a firearm, comprising:
- an upper receiver having a cavity therein and configured with at least an ejection port through which spent casings of ammunition cartridges are ejected when the firearm is in operation;
- a device movably attached to the upper receiver adjacent to a rear end of the ejection port to move linearly in directions parallel to a longitudinal axis of the upper receiver, the device comprises a shell deflector having a deflection surface configured to deflect the spent casings ejected out of the ejection port;
- and
- wherein the device further comprises a return spring, wherein the shell deflector is linearly movable between an idle position and a forward position, wherein, when pressed forwardly with respect to the upper receiver, the shell deflector moves from the idle position to the forward position with the return spring compressed, and wherein, when not pressed forwardly, the shell deflector returns to the idle position from the forward position by a first force exerted by the return spring.
