Embodiments of the present invention include a breech system comprising, first, a breech lock with a pivotable cam end plate for accessing a firearm breech and, second, a camming cartridge extractor with a pivotable lever for extracting a fired cartridge. The pivotable cam end plate may be connected to an independently pivotable arm that is operable as a lever for moving the cam end plate into an open position to allow breech access. The pivotable cam end plate and pivotable arm may be capable of a plurality of movements within the same plane in order to optimize leverage and cam action for opening the breech lock.

Disclosed is an extraction press assembly for facilitating removal of an object from a bore of a structure. The extraction press assembly comprises a coupling mount, a base plate, a support structure, and a press. The coupling mount can be configured to couple to the structure, thus securing the extraction press assembly to the structure. The base plate can be axially spaced from the coupling mount, and can support the press. The support structure can comprise axial extensions coupling the coupling mount to the base plate, and facilitating adjustment of the base plate (and thus the press) relative to the coupling mount. The press can be located between the coupling mount and the base plate and can be configured to expand and contract axially, and to exert a pressing force upon an extraction pole of an extraction pole assembly within the bore, which force is transferred to the object lodged within the bore. The press can be pivotally coupled to the base plate to rotate between a first position for extracting an object and a second position for accessing the bore.

A firearm includes a bolt mechanism with a bolt configured to receive a firing pin assembly and a bolt head assembly. The bolt head assembly includes a pivoting bolt head and an extractor. The extractor is positioned relative to the bolt such that substantially all forces applied by the extractor to the bolt mechanism are reacted within the bolt head assembly. A biasing member or element can urge a claw portion of extractor towards a distal end of the bolt head.
