First Claim
1. A firearm comprising:
- a receiver defining a bore with said receiver extending along a longitudinal axis and said receiver defining an ejection port transverse to said longitudinal axis with said bore defining an inner surface;
a bolt carrier disposed in said bore and moveable relative to said receiver along said longitudinal axis between a firing position and a rearward position; and
a shield longitudinally affixed to said bolt carrier and moving with said bolt carrier as a unit between said firing and rearward positions along said longitudinal axis, said shield being immovable relative to said bolt carrier along said longitudinal axis, and said shield blocking said ejection port when in said firing position and said shield sliding along said inner surface away from said ejection port when moving to said rearward position in conjunction with said bolt carrier.

Abstract
The present invention provides for a firearm having a receiver defining a bore with the receiver extending along a longitudinal axis. The receiver defines an ejection port transverse to the longitudinal axis with the bore defining an inner surface. The firearm further includes a bolt carrier disposed in the bore and moveable relative to the receiver along the longitudinal axis between a firing position and a rearward position. The firearm also includes a shield longitudinally affixed to the bolt carrier and movable with the bolt carrier as a unit between the firing and rearward positions along the longitudinal axis with the shield blocking the ejection port when in the firing position and the shield sliding along the inner surface away from the ejection port when moving to the rearward position in conjunction with the bolt carrier.

18. An ejection system for a firearm, said system comprising:
-
a receiver defining a bore with said receiver extending along a longitudinal axis and said receiver defining an ejection port transverse to said longitudinal axis; a bolt carrier disposed in said bore and moveable relative to said receiver along said longitudinal axis between a firing position and a rearward position; a door coupled to said receiver adjacent said ejection port with said door movable between a closed position covering said ejection port and a released position allowing said door to move away from said ejection port; a shield coupled to said bolt carrier and movable with said bolt carrier between said firing and rearward positions with said shield blocking said ejection port when in said firing position and said shield spaced from said ejection port when in said rearward position; and a release mechanism having a first portion coupled to said shield and a second portion coupled to said door with said first portion engaging said second portion as said shield moves from said firing position to said rearward position for moving said door from said closed position to said released position. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
