Abstract
A short bolt rifle that enables increased barrel without an increase in weight. A longer barrel increases bullet velocity, which increases the range and accuracy of the weapon and the bullet impact energy. In this action, the bolt is simply pulled back and pushed forward. The design includes a loader mechanism that ejects spent cartridges and loads a new cartridge. This happens while the bolt is drawn back and pushed forward. A rotating lock secures the bolt in the firing position. A second version of the action uses a pistol grip. A lock holds the pistol grip, which can be released. After it is released, the user pulls down and back on the grip to open the action. The grip is pushed forward and upward, to load a shell, while the bolt is moved forward and locked. The action also can easily be adapted to fully automatic operation.
Claims2
A short bolt rifle action, for a rifle, comprising:
- a) a barrel, said barrel having a receiver and at least one locking groove from about said receiver;
- b) a bolt, said bolt having a first end and a second end;
- c) at least one locking lug, fixedly attached to the first end of said bolt, whereby said locking lug is operably disposed to engage in said locking groove in said barrel;
- e) a slide, fixedly attached to said rifle;
- f) a pistol grip, slidably attached to said slide and being pivotably attached to said rifle, said pistol grip having a cam formed therein;
- and
- g) a cam follower, operably attached to said bolt and being aligned with said cam on said pistol grip, whereby when said pistol grip is pivoted in a first direction, said cam causes said bolt to turn about a longitudinal axis through a center of said bolt, thereby causing said locking lug to be aligned with said locking groove in said barrel, thereby releasing said bolt from said barrel, and when said pistol grip is pivoted in a second direction, said cam causes said bolt to turn about a longitudinal axis through the center of said bolt, thereby causing said locking lug to be misaligned with said locking groove in said barrel, thereby locking said bolt from said barrel.
