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 with said bolt carrier defining at least one exhaust port transverse to said longitudinal axis; and
a shield defining an aperture aligned with said exhaust port for exhausting gases therethrough with said 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 with 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
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. A bolt carrier is disposed in the bore and moves relative to the receiver along the longitudinal axis between a firing position and a rearward position with the bolt carrier defining at least one exhaust port transverse to the longitudinal axis. A shield defines an aperture aligned with the exhaust port for exhausting gases therethrough. The shield is longitudinally affixed to the bolt carrier and moves 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.
