Abstract

A firearm employs a gun recoil apparatus wherein the comb portion of the stock is fixed relative to a butt end plate. The stock includes a base portion movable with respect to the comb portion. The base portion has at least one guide bore therein which extends longitudinally with respect to the base portion. The butt end plate includes at least one guide rod affixed thereto which is received and slidable within the guide bore. Means are included for fixedly securing the comb portion of the stock to the guide rod whereby the base portion can, upon firing, move relative to the comb portion and butt end plate. Means are provided for adjusting the height of the comb portion above the base portion.

Claims

1. A shoulder firearm comprising,

an elongate stock including a base portion and an upper comb portion, the upper comb portion being movable longitudinally with respect to said base portion, said base portion having a guide bore therein extending longitudinally with respect to said base portion;

a butt plate;

a guide rod fixed to said butt plate and slidable within said guide bore;

two mounting pins threadedly mounted to said guide rod and extending upwardly therefrom, the mounting pins being slidably received in two elongate slots in the base portion which extend upwardly from the guide bore to the upper portion of the base, the mounting pins further being slidably received in respective vertical metal sleeve-lined bores in the comb portion;

the comb portion having horizontal bores extending from the outer side comb surface to the comb vertical bores, the metal sleeves lining the vertical bores each having a threaded bore axially aligned with the comb horizontal bores, threaded set screws being threadedly received in the metal sleeves which, when inwardly threaded and torqued, bear against the respective mounting pins whereby the comb portion is secured against vertical movement, whereby the height of the comb is adjustable relative to the guide rod and base portion, and whereby the base portion can move relative to the butt plate and comb portion.

2. A shoulder firearm comprising:

an elongate stock including a base portion and an upper comb portion, the upper comb portion being longitudinally movable with respect to the base portion, the base portion having a guide bore therein extending longitudinally with respect to the base portion;

a butt plate;

a guide rod fixed to the butt plate and slidable within the guide bore; and

means for fixedly securing the comb portion to the guide rod whereby the base portion can move relative to the butt plate and comb portion, said means comprising two mounting pins secured to and upwardly extending from the guide rod into respective vertical bores in the comb portion and wherein an upper portion of the base includes two elongate slots which extend to the guide bore for slidably receiving the two mounting pins whereby axial movement of the base portion is permitted relative to the two mounting pins.

3. The shoulder firearm of claim 2, wherein the mounting pins are threadably received in the upper portion of the guide rod.

4. The apparatus of claim 2 wherein the position of said comb portion with respect to said mounting pins is adjustable vertically, and fastener means operatively arranged between said comb portion and said mounting pins for securing said comb portion in selected position on said pins.

5. A recoil apparatus for a shoulder firearm, the shoulder firearm including an elongate stock having a base portion and an upper comb portion, the upper comb portion being longitudinally movable with respect to the base portion, the base portion having a guide bore therein extending longitudinally with respect to the base portion, the firearm having a butt end piece separate from the comb portion and base portion, the recoil apparatus comprising,

a guide rod adaptable to be slidably received in the guide bore;

means for fixedly securing the guide rod to the butt end piece; and

means for fixedly securing the comb portion to the guide rod whereby the base portion can move relative to the butt end piece and comb portion, said means for fixedly securing the comb portion to the guide rod comprising a pair of mounting pins secured to and upwardly extending from the guide rod, the mounting pins adapted to be received in respective vertical bores in the comb portion.

6. The apparatus of claim 5 wherein the mounting pins are threadedly received in the upper portion of the guide rod.
