Abstract: A machine gun (e.g., a minigun) is provided with a modular delinker. The front of the delinker (i.e., nose) can be removed from the main body of the delinker without tools. The paddle wheel in the main body includes a front paddle wheel and a rear paddle wheel. The front paddle wheel is removable from the main body with the nose, and the rear paddle wheel remains within the main body on a driven shaft of the delinker when the nose is removed from the main body. Thus, some components of the delinker are accessible and serviceable without tools, and the nose and front paddle wheel may be swapped out without tools out to alter a compatible ammunition cartridge type of the delinker. A jam can be cleared and damaged front and/or rear paddle wheels can be replaced in the field to return a gun to service.

Abstract: A firearm lock mechanism includes a trigger, a hammer, a stirrup connected to the hammer at a stirrup connection point, and a spring operably connected to the stirrup at a spring connection point. Progressive pivoting of the trigger drives corresponding progressive pivoting of the hammer. The stirrup connection point is disposed forward of the hammer pivot point. One of the spring connection point, hammer pivot point, and stirrup connection point is offset relative to and laterally spaced between the others of the points to be a vertex of an intermediate angle cooperatively defined by the points. The angle increases in magnitude as the trigger drives pivoting of the hammer. A toggle line is defined between the trigger pivot point and the hammer pivot point. The trigger contacts the hammer at a contact point that shifts across the toggle line as the trigger drives pivoting of the hammer.
