DESCRIPTION OF THE CURRENT EMBODIMENT

[0015] An embodiment of the rifle stock of the present invention is shown and generally designated by the reference numeral 10.

[0016] FIGS. 1-5 illustrate the improved rifle stock 10 of the present invention. More particularly, FIG. 1 shows the rifle stock in use attached to a rifle 12. The rifle includes a barreled receiver 14 defining a barrel axis 16. The rifle stock has an elongated frame element 18 having a forward end 20 configured to connect to the barreled receiver of the rifle. In the current embodiment, the forward end has a threaded portion 22 that is compatible with the castle nut 94 of an AR-style rifle, such as the rifle illustrated. The elongated frame element defines a frame axis 24 parallel to the barrel axis. The frame element has an elongated first attachment facility 26 extending along the length of the frame element and defining a first plurality of attachment locations 28. The elongated frame element has an elongated second attachment facility 30 extending along the length of the elongated frame element and defining a second plurality of different attachment locations 32. A cheek riser 34 is connected to the first attachment facility. A butt assembly 36 is connected to the second attachment facility.

[0017] At least one of the first and second attachment facilities 26, 30 is a rail 38 having an unlimited number of attachment positions. At least one of the first and second attachment facilities is a rail 40 having a limited number of discrete attachment positions. Preferably, the other of the first and second attachment facilities is a rail 38 having an unlimited number of attachment positions. The rail 40 defines a plurality of stop surfaces 42 configured to prevent axial movement of a connected element 44, which is an upper portion of the butt assembly 36. Resistance to axial movement is critical because the connected element must convey recoil forces resulting from discharge of the rifle 12 into the butt assembly 36 and ultimately into the user's shoulder (not shown) via a vertical butt pad 64. The rail 40 is a picatinny rail in the current embodiment. The first and second attachment facilities are parallel to each other and extend along a major portion of the length of the frame element in the current embodiment.

[0018] The cheek riser 34 has a riser block 46 connected to the elongated frame element and a cheek support element 48 vertically movable with respect to the riser block. The elongated frame element 18 defines an upwardly open elongated channel 50, and the cheek riser includes vertical support bars 52 at least in part received in the channel. The height of the cheek riser is maintained at a user-selected position by the engagement of a set screw 54 with each of the vertical support bars. The axial position of the cheek riser is maintained at a user-selected position by the engagement of left and right clamps 56, 58 that are clamped against the rail 38 by bolt 60. The bolt includes an enhanced grip portion 62 to facilitate ease of adjustment of the axial position of the cheek riser without requiring tools. The cheek riser receives minimal recoil force, so greater ease of adjustment of axial position with potentially somewhat reduced resistance to axial movement relative to the connected element 44 is suitable.

[0019] The butt assembly 36 includes the vertical butt pad 64, which is located rearward of the elongated frame element 18. A portion of the vertical butt pad is registered with the frame axis 24. The vertical butt pad can allow both height and rotational adjustment relative to the butt assembly. In the current embodiment, the connected element 44 of the butt assembly is a picatinny rail. The connected element is secured to the rail 40 by the engagement of left and right clamps 66, 68 that are clamped against the rail 40 by bolts 70. The butt assembly optionally includes left and right side panels 72, 74, which are secured to the butt assembly by screws 76 to cover aperture 78 defined by the butt assembly. The side panels can be weights, covers to create a storage area within the aperture, or decorative features to customize the appearance of the rifle stock 10. The butt assembly also optionally includes a foot plate 80, which is secured to the bottom 82 of the butt assembly by three screws 84. The foot plate can be a weight or a decorative feature to customize the appearance of the rifle stock.

[0020] The elongated frame element 18 includes locational indica 86 along the length of the elongated frame element. Preferably, the locational indicia are associated with rail 40 and denote a length of pull of the rifle 12 that is associated with the location of connection of the connected element 44 of the butt assembly 36 to the rail 40. The elongated frame element has a cross-section that is wider at the top 88 and bottom 90 than at an intermediate position 92.

[0021] In the context of the specification, the terms “rear” and “rearward,” and “front” and “forward,” have the following definitions: “rear” or “rearward” means in the direction away from the muzzle of the firearm while “front” or “forward” means it is in the direction towards the muzzle of the firearm.

[0022] While a current embodiment of a rifle stock has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. Although rifles have been disclosed, the rifle stock is also suitable for use with shotguns, light and medium machine guns, and other firearms. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

[0023] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
