Abstract
An improved gun stock construction that substantially reduces both the recoil and the tendency of the gun to move upward or jerk when it is fired. The stock is formed with two sections having a flexible hinge mechanism. This structure creates a moment arm or couple which opposes the tendency of the gun to move upward when it is fired. This invention relates to improvements in a gun construction and more particularly to the improvement in gunstock that permits better control of the gun by the operator.
Claims17
A gun stock for a fully-automatic gun having a receiver tube comprising:
- (a) a two-section support in which the sections are associated for relative motion about an axis transverse to the line of fire and adjacent the top of the support, said sections being spaced to permit dosing of a gap below said axis in response to recoil force of said gun, the closing of a gap below said axis being considered as a closing action;
- (b) a means for securing said receiver tube within said two-section support, wherein said receiver tube having a recoil force line below said axis, and
- (c) a means for resiliently resisting said closing action, such that when the recoil energy moves the gun barrel down after each shot, the reaction of said means for resiliently resisting said closing action moves the gun barrel up to the original attitude;
- (d) wherein said means for resiliently resisting said closing action including at least one pin positioned in an arcuate channel, said arcuate channel being formed in said two section support and being positioned below said axis.
A gun stock for a fully-automatic gun having a receiver tube comprising:
- a) a rear support section, having a top, and a receiver tube channel, wherein said receiver tube channel having an axis aligned with a line of fire of said fully-automatic gun;
- b) a front support section, having a top, and a receiver tube channel, wherein said receiver tube channel having an axis aligned with a line of fire of said fully-automatic gun;
- c) a means for pivotably attaching said rear support to said front support at the top of said rear support and said front support;
- d) an arcuate channel formed in said rear support, below said receiver tube channel;
- e) a pin, having a flat head, slidably engaged in said arcuate channel;
- and
- f) a slot in said front support for receiving the flat head of said pin, whereby when said fully-automatic gun is fired, a recoil generated along said axis causes said front support to pivot with said rear support in an arcuate path defined by the movement of said pin in said arcuate channel.
