Abstract
A modular bolt action for a bolt action firearm is provided. The bolt action includes a receiver and a bolt assembly, the receiver being reconfigurable in a variety of different ways to accommodate a variety of different bolt assemblies. In this way, the modular bolt action can be reconfigured from a left-handed action to a right-handed action and/or from a two-lug action to a three-lug action. Fabrication of the modular bolt action includes adjusting the receiver to accommodate a desired bolt assembly and engaging such bolt assembly with the receiver.
Claims15
A modular bolt action comprising:
- a receiver assembly comprising a receiver body and an extraction cam coupled thereto;
- and
- a bolt assembly comprising a bolt body and a bolt handle extending outwardly from a first portion of said bolt body, said receiver body defining an inner cavity for receiving a second portion of said bolt body,
- wherein the modular bolt action is movable between a right-handed configuration and a left-handed configuration,
- wherein said bolt assembly rotates about a longitudinal axis of said receiver assembly as said bolt assembly moves between a locked configuration and an unlocked configuration,
- wherein said bolt assembly slides along the longitudinal axis as the bolt assembly moves between a closed configuration and an open configuration,
- wherein the modular bolt action is one of a first type or a second type,
- wherein for the first type of modular bolt action;
- said extraction cam is a left-handed extraction cam or a right-handed extraction cam, and
- moving the modular bolt action from the left-handed configuration to the right-handed configuration comprises replacing a left-handed extraction cam with a right-handed extraction cam, and
- wherein for the second type of modular bolt action;
- said extraction cam is an ambidextrous extraction cam;
- the bolt assembly is a left-handed bolt assembly or a right-handed bolt assembly;
- and
- moving the modular bolt action from the left-handed configuration to the right-handed configuration comprises replacing the left-handed bolt assembly with the right-handed bolt assembly.
A method of converting a firearm from a left-handed configuration to a right-handed configuration, the firearm comprising a modular bolt action having a receiver assembly and a bolt assembly, the receiver assembly having a receiver body and a left-handed extraction cam, the method comprising:
- removing the left-handed extraction cam from the receiver body and installing a right-handed extraction cam to the receiver body.
A method of converting a firearm from a left-handed configuration to a right-handed configuration, the firearm comprising a modular bolt action having a receiver assembly and a bolt assembly, the receiver assembly having a receiver body and an ambidextrous extraction cam, the method comprising:
- disengaging and removing the bolt assembly from the modular bolt action, the bolt assembly being a first bolt assembly;
- and
- engaging with the modular bolt action one of the first bolt assembly and a second bolt assembly;
- and
- converting the first bolt assembly to the second bolt assembly by removing a first nub from a bolt of the bolt assembly and installing a second nub to the bolt of the bolt assembly,
- wherein the first bolt assembly is a left-handed bolt assembly, and
- wherein the second bolt assembly is a right-handed bolt assembly.
A firearm comprising:
- a modular bolt action that is movable between a right-handed configuration and a left-handed configuration, the modular bolt action comprising:
- a receiver assembly comprising a receiver body and an extraction cam coupled thereto;
- and
- a bolt assembly comprising a bolt body and a bolt handle extending outwardly from a first portion of said bolt body, said receiver body having opposed first and second ends and defining an inner cavity for receiving a second portion of said bolt body,
- wherein said bolt assembly rotates about an axis relative to said receiver assembly between a locked configuration and an unlocked configuration, the degree of said rotation limited by said extraction cam engaging with said bolt assembly at an engagement point,
- wherein said bolt assembly slides along said axis relative to said receiver assembly between a closed configuration and an open configuration,
- wherein said extraction cam is capable of removal from said receiver body, thereby facilitating a greater degree of rotation by said bolt assembly relative to said receiver assembly.
