Abstract:
1. In a semi-automatic fire, closed bolt, delayed blow back-type carbine, wherein no lower feed lips are employed, an anti-jamming cartridge loading system comprising: a) the closed bolt having a firing pin recessed within the closed bolt when the carbine is ready to fire; b) the closed bolt having a nose bolt including an extractor mounted upon an outer end circumference thereof and an ejector slot formed in a side portion therein; c) the nose bolt having a recess formed on a terminal end receiving a pivot plate, the pivot plate rotating about an axle such that the pivot plate is in a collapsed state before the bolt is in a ready fire position and the pivot plate is in a non-collapsed state when the bolt has reached its most forward position such that the firing pin protrudes through an aperture formed in the pivot plate far enough to strike a cartridge positioned in a breech area of the carbine.
