Abstract
A bolt action firearm that cocks the firing pin upon closing the bolt and includes a cam pin with dual heads for a high velocity rimfire cartridge. In one embodiment, actuating the main spring while closing the bolt, instead of while opening the bolt, more uniformly distributes the physical energy required by the user over the bolt actuation cycle. The dual heads of the cam pin provide symmetric reactive forces with dual cam slots, thereby preventing the cam pin from skewing or canting within the cam slots. A safety system is provided for the trigger mechanism and a robust connecting systems for the stock.
Claims14
A firearm, comprising:
- a receiver;
- a barrel attached to said receiver;
- a dual cam bolt adapted to engage with said receiver, said dual cam bolt including a firing mechanism having a main spring and firing pin;
- a trigger assembly having a stop lever, said stop lever being selectively movable between a blocking position and a non-blocking position,
- wherein said stop lever is finger actuated proximate to a finger portion of the trigger, and
- wherein in the non-blocking position the sear is rotatable to release the main spring to discharge the firearm.

A bolt action firearm comprising a bolt assembly, the bolt assembly including:
- a main body defining central bore along a central axis and having a neck portion with a pair of elongate slots that pass through said neck portion, said elongate slots being diametrically opposed to each other;
- a cam cylinder mounted to an external surface of said neck portion, said cam cylinder having diametrically opposed spiral-shaped slots, said spiral shaped slots being in mirrored symmetry about said central axis;
- a spring retainer slidably engaged within said central bore at said neck portion, said spring retainer including a pin that passes laterally therethrough, said pin extending through said pair of elongate slots of said neck portion and through said diametrically opposed spiral-shaped slots of said cam cylinder;
- and
- a main spring disposed distal to and in contact with said spring retainer,
- wherein rotation of said bolt assembly from an open position to a closed position causes said cam to exert a force on said cam pin, which causes said cam pin and said spring retainer to move in a distal direction, applying a compressive force on said main spring.
