Abstract
The invention comprises an improved recoil control device comprising a bolt head and an inertia block for use in a variety of firearms. In one embodiment, the bolt head and inertia block are articulated so that the displacement of the bolt head results in a force component outside the firing axis of the barrel of the firearm. The device can be incorporated into firearms of a variety of sizes and configurations to produce recoil reduction and/or weight reduction advantages.
Claims61
A recoil control system for a heavy weapon comprising:
- at least one inertia block for receiving a first momentum component perpendicular to the longitudinal axis of the barrel;
- and
- a bolt head configured to alternate between a forward position and a rearward position in response to the movement of at least one inertia block.
- whereby the reactive jerking of the firearm is reduced.
A firearm with a plurality of barrels comprising:
- a gas injection system for applying a portion of high-pressure gases from the firing of one or more cartridges to at least one inertia block;
- a first inertia block for receiving a first momentum component perpendicular to the longitudinal axis of the barrel imparted by the gas injection system;
- a second inertia block for receiving a second momentum component perpendicular to the longitudinal axis of the barrel imparted by the gas injection system;
- a first bolt head associated with a first barrel configured to alternate between a first forward position and a first rearward position in response to the movement of a least one of the first inertia block and the second inertia block;
- and
- a second bolt head associated with a second barrel configured to alternate between a second forward position and a second rearward position in response to the movement of a least one of the first inertia block and the second inertia block,
- whereby the reactive jerking of the firearm is reduced.
A method of controlling recoil in a heavy weapon comprising:
- firing a projectile that generates high-pressure gases;
- and
- applying a portion of the high-pressure gases to a first inertia block to impart a first momentum component perpendicular to the longitudinal axis of the barrel to the first inertia block,
- whereby the reactive jerking of the firearm in response to the recoil forces is reduced.
