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.
Claims45
A recoil control device for use in a firearm, comprising:
- a bolt head configured to alternate between a forward position and a rearward position in response to the firing of one or more cartridges;
- and
- an inertia block connected to the bolt head such that said bolt head imparts an impulse to the inertia block as it alternates between the forward position and the rearward position, the movement of the inertia block having a component lateral to or perpendicular to the firing axis of the barrel of the firearm, whereby the reactive recoil forces are substantially reduced.
A recoil control device for use in a semiautomatic or automatic firearm, said device comprising:
- a mobile breech comprising a bolt head and an inertia block;
- the bolt head configured to alternate between a forward position and a rearward position in response to the percussion of one or more cartridges, the bolt head comprising a first leading surface sloped to make contact with a-second sloped surface on the inertia block in order to transmit an impulse to the inertia block as it alternates between the forward position and the rearward position, whereby the reactive recoil forces are substantially reduced.
A frameless heavy weapon comprising:
- a bolt head configured to alternate between a forward position and a rearward position in response to the percussion of one or more cartridges;
- a first inertia block connected to the bolt head so that said bolt head imparts a first impulse to the first inertia block as the bolt head alternates between the forward position and the rearward position, the first impulse having a component perpendicular to the firing axis of the barrel of the firearm;
- and
- a second inertia block connected to the bolt head so that said bolt head imparts a second impulse to the second inertia block as the bolt head alternates between the forward position and the rearward position, the second impulse having a component perpendicular to the firing axis of the barrel of the firearm;
- wherein the first inertia block and the second inertia block are synchronized such that the perpendicular component of the momentum of the first inertia block substantially offsets the perpendicular component of momentum of the second inertia block such that the weapon is not agitated thereby.
A firearm with a plurality of barrels, comprising:
- 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 percussion of a first one or more cartridges;
- 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 percussion of a second one or more cartridges;
- a first inertia block connected to at least one of the first and second bolt heads such that said at least one bolt head imparts a first impulse to the first inertia block as it alternates between the first forward position and the first rearward position, the first impulse having a component perpendicular to the firing axis of the first barrel of the firearm;
- and
- a second inertia block connected to at least one of the first and second bolt heads such that said at least one bolt head imparts a second impulse to the inertia block as it alternates between the forward position and the rearward position, the second impulse having a component perpendicular to the firing axis of the second barrel of the firearm.
A method for controlling the recoil in a semiautomatic or automatic firearm, said method comprising:
- firing a projectile that generates recoil forces;
- and
- transferring at least a portion of the recoil forces to an inertia block, whereby the inertia block is imparted with a momentum component perpendicular to the longitudinal axis of the barrel;
- whereby the reactive jerking of the firearm in response to the recoil forces is reduced.
A recoil control device for use in a semiautomatic or automatic firearm, said device comprising:
- p1 Atty Docket:
- 81005-0006 a recoil transfer mechanism for transferring recoil forces in a direction other than along the axis of the barrel of the gun;
- and an inertia block for receiving at least a portion of recoil forces and directing said recoil forces in a direction perpendicular to the longitudinal axis of the barrel of the firearm, wherein the recoil transfer mechanism comprises a gas injection system for imparting momentum to the inertia block.
