DETAILED DESCRIPTION

(8) The following detailed description and figures are merely example embodiments and are not intended to limit the disclosure to any particular embodiment provided herein. It is to be understood that there may be a variety of alternate embodiments not provided in the figures. The figures are not necessarily to scale, and some features may be excluded, altered in size or shape in order to show details of particular components. Specific structural and functional details and the materials utilized for the structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for teaching one skilled in the art to employ the varying embodiments of the present disclosure.

(9) FIG. 1 is one possible embodiment showing a perspective view of the butt stock 100 attached to a buffer tube 102 of a firearm 104. It is important to note that this particular firearm 104 may be an AR-15, a typical firearm that would utilize this embodiment of the butt stock 100 shown in FIG. 1, however, there are many similar models of firearms such as the M4 that have similar buffer tubes to which the butt stock 100 can be attached and the embodiments described herein are not limited to any particular firearm. In some embodiments the butt stock 100 may be configured and sized to slide onto the buffer tube 102 of the firearm 104. In some embodiments, the butt stock 100 may be configured with a fastener to fasten the butt stock 100 to the buffer tube 102. A typical fastener that may fasten the butt stock 100 to the buffer tube 102 may be a threaded fastener, a lock pin fastener, a cam fastener, a magnetic fastener, or any similar type of fastener capable of fastening the butt stock 100 to the buffer tube 102.

(10) In a typical firearm, the buffer tube is cylindrical in shape and has a set of slots arranged in a lower portion of the buffer tube for receiving a locking pin to lock the butt stock 100 into place. The set of slots allow for an adjustment of the butt stock position in relation to the operator and the firearm, lengthening or shortening the overall length (e.g., the pull) of the firearm. Typically, there are four slots arranged in half inch increments on the buffer tube 102 allowing for four inches of adjustment of the length of the weapon. In some embodiments the butt stock 100 may be configured with a locking pin mechanism to lock the butt stock 100 to the buffer tube 102.

(11) In some embodiments the buffer tube 102 may be configured with an anti-rotation rail positioned at a top portion and/or a lower of the buffer tube to prevent the butt stock 100 from rotating out of alignment with the firearm 104. In some embodiments the butt stock 100 may be configured with an anti-rotation rail to prevent rotation of the butt stock 100 on the buffer tube 102. In some embodiments the butt stock 100 may be configured with an anti-rotation receiving slot to prevent the rotation of the butt stock 100.

(12) FIG. 2 is a perspective view of one possible embodiment of the butt stock 100 configured with a receiving member 207, a receiving bore 202 detached from the buffer tube 102. In some embodiments the butt stock 100 may be configured to be fastened to a receiving bore 202 sized appropriately to attach to the buffer tube 102 of the firearm. This configuration may increase the pull length of the firearm. Buffer tube 102 size may typically be 0.5 inches in diameter but may be larger or smaller depending on the firearm 104 to which the receiving bore 202 and the butt stock 100 is attached. In some embodiments the receiving bore 202 of butt stock 100 may have an internal dimension slightly larger than 0.5 inches. In some embodiments the receiving member 207 of the butt stock 100 may be configured to have an internal diameter slightly larger than 0.5 inches.

(13) In some embodiments the receiving bore 202 may be configured with at least one lock pin 204 for securing the butt stock 100 to the buffer tube 102. The butt stock 100 is not limited to utilizing a lock pin mechanism to secure the butt stock 100 to the buffer tube 102, but may utilize any one of a threaded fastener, a pin, a twist lock, a cam lock, or any suitable fastener that secures the butt stock 100 to the buffer tube 102. A more detailed description of the lock pin 204 will be provided in the following paragraphs.

(14) In some embodiments the butt stock 100 may be configured with a receiving member 207. The butt stock 100 may be fastened to the receiving bore 202 or it may be fastened to buffer tube 102 directly by a receiving member 207. In some embodiments the butt stock 100 may be molded to the receiving bore 202 or it may be attached by a fastener. In some embodiments the receiving member 207 of the butt stock 100 may be sized to slide onto the receiving bore 202 and/or the buffer tube 102. In some embodiments the butt stock 100 may be sized appropriately for an operator, the butt stock may be 1-2 inches in diameter, 2-3 inches in diameter, 3-4 inches in diameter, 4-5 inches in diameter, 5-6 inches in diameter, or may be sized according the intended use by the operator. In some embodiments the butt stock 100 may be configured to house additional internal components, a detailed description of which will be provided in the following paragraphs. In some embodiments, the aforementioned size configurations provides increased stability during operation when the firearm 104 is operated at 0 to 180 bi-directionally in relation to the operator's body as opposed to a traditional butt stock that is a narrow body aligned with a vertical plane of the firearm. During operation of the firearm 104, a traditionally shaped butt stock (e.g., a narrow strip vertically aligned with the firearm 104) is positioned in the shoulder cup of the operator. Under certain conditions (e.g., when the firearm 104 is operated while in the prone position) the operator is unable to stabilize the weapon in the shoulder cup due to a position of the magazine or other interferences. Under these conditions a butt stock 100 with a spherical shaped or spherical analogue shape provides an increased surface area for stabilization of the weapon on nearly any surface of the operator's body. In some embodiments, the butt stock 100 may be configured in a prolate spheroid shape, an oblong shape, a truncated icosahedrons and/or any similarly related three dimensional analog shape that provides stabilization of the weapon. In some embodiments the butt stock 100 may be configured with an attachment point 208. The attachment point 208 may provide a fastening point for fastening a sling or any similar component that would be fastened to the butt stock 100.

FIG. 3 is one possible embodiment showing the internal mechanisms of the lock pin 204 and the internal lock 300 of the buffer tube 102 for attaching the butt stock 100 to the buffer tube 102. In some embodiments, the lock pin 204 consists of a housing 302 a spring 304 and a pin 306. In some embodiments the butt stock 100 may be removed from the buffer tube 102 in the manner described hereafter. To remove the butt stock 100 from the buffer tube 102 the operator grasps the lock pin 204 and pulls away from the receiving member 207 compressing the spring 304 this action causes the pin 306 to retract from the buffer tube 102, the operator may then slide the butt stock 100 off the buffer tube 102.

(16) In some embodiments the butt stock 100 may be securely fastened to the buffer tube 102 by a pin 306 that travels into the buffer tube 102. In some embodiments the butt stock 100 may be securely fastened to the buffer tube 102 by a threaded insert that fastens the butt stock 100 to the buffer tube 102. In some embodiments the butt stock 100 may be securely fastened to the buffer tube 102 by several lock pins or threaded insert configurations, a cam lock, a twist lock, or any combination thereof and is not limited to any one configuration described herein.
