ABSTRACT:
A firearm which has a receiver formed with an ejection port through which the cartridge case of a spent cartridge is ejected. A bolt is situated in the receiver for movement between a forward firing position and a rear retracted position, a cartridge case being ejected when the bolt is in its rear retracted position. The bolt is also supported in the receiver for rotary movement between locked and unlocked positions. A sleeve is operatively connected to and surrounds the bolt for rotating the latter between its locked and unlocked positions, this sleeve having a length substantially less than the length of the bolt and covering part of the ejection port when the bolt is in its firing position. A cover is provided to cover that part of the port which is not covered by the sleeve when the bolt is in its firing position, and this cover responds to rearward movement of the bolt from its firing to its retracted position for uncovering the ejection port.
