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.
Claims23
A recoil control device in combination with a firearm having a barrel, the device comprising:
- a bolt head configured to alternate between a forward position within the axis of the barrel and a rearward position tilting out of the axis of the barrel, the alternating positions in response to the firing of one or more cartridges;
- and
- an inertia block positioned at the rearward end of the bolt head such that said bolt head imparts an impulse to the inertia block as the bolt head 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, the inertia block having a first surface for receiving an impulse from the bolt head when the bolt head is at a forward position and the bolt head within the axis of the barrel, and the inertia block having a second surface for receiving an impulse from the bolt head as the bolt head moves to a rearward position and the inertia block advances to the end of its movement, wherein the first and second surfaces have different angles relative to the axis of the barrel.
A recoil control device in combination with a semiautomatic or automatic firearm having a barrel, 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 first 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, the inertia block having both a first sloped surface and a second sloped surface to make contact the bolt head, and the movement of the bolt head at the rearward position tilts out of the axis of the barrel of the firearm.
