Ambidextrous bolts that allow a user to quickly and easily change the side of the firearm from which a spent casing is ejected by application of a simple switching mechanism that does not require disassembly of the firearm. Aspects of the disclosure also include debris shields for improving the longevity and reliability of extractors, firearms that are configured for ambidextrous operation, methods of using firearms, and methods of modifying firearms to incorporate ambidextrous functionality.

An assembly of a breech (1), a breech block (2) and an ejector (3) wherein the breech (1) is connected to the breech block (2) with the use of a groove (10), arranged in the breech block (2), and a corresponding recess, arranged in the breech (1). An ejector (3) is arranged in the breech (1) that is longitudinally adjustable in a sliding way between the front and rear end position. The ejector (3) is biased by a spring (6) against the shooting direction. On the back of the ejector (3) a recess is arranged that a peg (7) that protrudes from the breech (1) reaches into. At the rear side of the ejector (3), a longitudinal pin (4) is arranged that fits into an opening (5) in the breech block (2) in the rear end position of the ejector (3). On the part of the ejector (3) that protrudes out of the breech (1), a stop surface (9) is arranged for bearing on the breech guide (11) that protrudes out of the breech (1) block.

Firearms with combined bolt catch and ejector have a bolt defining a bolt face configured to receive a case head of a cartridge, a bolt catch connected to a frame and movable between a first operational position in which bolt reciprocation forward from the rear position is enabled, and a second restraining position in which a portion of the bolt catch restrains the bolt in the rear position, and the bolt catch having an ejector surface portion positioned clear of the bolt face when the bolt catch is in the first operational position and in registration with a portion of the bolt face when the bolt catch is in the second restraining position such that a case head received by the bolt face strikes the ejector surface portion upon movement of the bolt from the forward to the rearward position when the bolt catch is in the second restraining position.
