Abstract
The invention comprises an improved recoil control device comprising a bolt head and an inertia block or slider 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.
Claims32
A firearm comprising:
- a barrel with a chambering end and a muzzle end;
- a handgrip having a top end and a bottom end, wherein the handgrip is positioned behind the chambering end of the barrel and wherein the handgrip is positioned relative to the barrel such that the longitudinal axis of the barrel intersects the handgrip at between about 5% to about 95% of the height relative to the top end of the handgrip;
- and
- a bolt head configured to alternate between a forward position and a rearward position during a firing cycle and the bolt head operably linked to a slider, whereby the movement of the bolt head in response to the firing of a round imparts a momentum to the slider causing the slider to move along a slider path, and wherein the bolt head leaves the longitudinal axis of the barrel during part of the firing cycle.
A recoil control device for use in a firearm, said device 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 wherein the bolt head leaves the longitudinal axis of the barrel during part of the movement between forward and rearward positions;
- and
- a slider connected to the bolt head, the slider comprising a surface to contact the bolt head or a linkage to bolt head;
- wherein the bolt head is configured to transmit an impulse to the slider as it alternates between the forward position and the rearward position, and wherein the movement of the slider has a component perpendicular to the longitudinal axis of the barrel of the firearm.
A semiautomatic or automatic 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 wherein the bolt head leaves the longitudinal axis of the barrel during part of the movement between forward and rearward positions;
- and
- a slider comprising an initial or first sloped surface and a second sloped surface to contact the bolt head or a linkage to the bolt head;
- wherein the bolt head is configured to transmit an impulse to the slider as it alternates between the forward position and the rearward position, the impulse having a component perpendicular to the firing axis of the barrel of the firearm.
