(46) The best mode for carrying out the invention is presented in terms of a preferred, a second and a third embodiment. The preferred embodiment is shown in FIGS. 1, 2 and 4 thorough 18 which is comprised of a tactical adaptive rifle stock 10. The rifle stock 10 includes an existing multi-axis adjustable buttstock 12, having a grip neck 14, a butt 16 and a flanged stock bolt 18 which is disposed through a portion of the buttstock 12.

(47) A stock fore-end set 20, which is illustrated in FIG. 2, consists of a receiver portion 22 and a forestock portion 24, with the receiver portion 22 incorporating a number of rear threaded holes 26 aligned in a bolt circle 28, illustrated in FIG. 5, and buttstock threaded fasteners 30, depicted in FIG. 4 for connecting the buttstock flanged stock bolt 18 to the threaded holes 26 in the receiver portion 22.

(48) The receiver portion 22 incorporates a rifle action and barrel cavity 32, shown in FIG. 2, forms a longitudinal receiver bedding interface surface 34, illustrated in FIG. 7. The radius in the receiver portion is larger than the radius of a rifle action 36 providing the uniform converging contact point, permitting a rifle action front trigger guard screw and a rear trigger guard screw to apply compressive pressure to the rifle action 36 creating the constant longitudinal alignment without peripheral interference.

(49) The rifle action 36 includes a barrel 36a and has a short action receiver or a long action receiver 36b. The short action receiver is illustrated in the drawings and the long is not shown, however, it incorporates the same features except its overall length is greater. The short and long action designation is well known in the industry and the tactical adaptive rifle stock 10 embraces either configuration.

(50) The receiver portion 22 is adapted to conform to the rifle action 36 having a recoil lug 38, with the receiver portion 22 having a recoil lug pocket 40, depicted in FIG. 3, with a bottom, a rear face, a front face and sides. Two front face threaded fasteners 42, shown in FIG. 10, engage the front face of the recoil lug 38 through threads in the forward bulkhead 44 and compress the recoil lug 38 against the rear face of the recoil lug pocket 40. A recoil lug side threaded fastener 46, in the form of a socket head set screw, engage a right side and left side of the recoil lug 38 thereby centering and retaining the sides of the recoil lug 38 within the receiver portion 22. The recoil lug 38 is positioned above the bottom of the recoil lug pocket 40 in order to permit the longitudinal receiver bedding interface surface 34 to accomplish the sole longitudinal receiver bedding interface surface 34.

(51) The receiver portion 22 incorporates a locking wedge recess 48 positioned adjacent to the recoil lug pocket 40, with a locking wedge 50, illustrated in FIG. 13, including a threaded bore 52. The receiver portion 22 further includes a set of vertical dovetail grooves 54 in a forward side and a semi-circular recess 56 in a forward bottom end.

(52) The forestock portion 24 illustrated in FIGS. 11-18 and has a dovetail joint 54, a semi-circular outwardly facing platform 58, a rear bulkhead 60 and a front face 62. The forestock portion 24 includes a bottom 66 and sides 68 each having a plurality of threaded bottom holes 70 and threaded side holes 72 adapted to mate with military specification Picatinny Rail hole spacing's. The forestock portion front face 62 has a number of accessory front face threaded holes 74 that continue completely through. The forestock portion 24 may be any overall length, however it is preferred that the forestock portion has an overall length of 6.25, 8.25 and 10.25 inches (15.88, 20.96 and 25.11 cm) which is a typical for a tactical stock of this type.

(53) The forestock portion 24 optionally includes accommodations for mounting a flashlight which is designated the flashlight forestock 76 as illustrated in FIGS. 19-24, which includes a plurality of flashlight threaded holes 78 interfacing with a specific tactical flashlight. Further the forestock portion 24, for this option, incorporates side slots 80 for manipulating the flashlight switch, and a round opening 82 in the front face 62 for the light beam to pass through.

(54) The fore-end receiver portion 22 and forestock portion 24 combined set 20 are individually made of aluminum, preferably anodized. Specifically the multi-axis adjustable buttstock 12, receiver portion 22 and forestock portion 24 include lightening areas 98 in the interior to reduce the overall weight of the tactical adaptive rifle stock.

(55) The forestock portion 24 is united with the receiver portion 22, by utilizing the dovetail joint 54 and the semi-circular platform 58 simultaneously juxtaposes with the semi-circular recess 56. When a locking wedge threaded fastener 64 enters the locking wedge bore 52, and is tightened, the receiver portion 22 and the forestock portion 24 are fully mated together, forming the combined set 20 for the tactical adaptive rifle stock 10. The fore-end 20, combined receiver portion 22 and forestock portion 24 have lightening areas 94 for reducing overall weight.

(56) The second embodiment of the tactical adaptive rifle stock 10 is depicted in FIG. 25 and the details are shown in FIGS. 26-41. The second embodiment utilizes the same buttstock 12 which is attached only to the receiver portion 22 with the forestock portion 24 replaced by an adapter 84 which is connected directly to the receiver portion 22. The adapter 84 consists of a mating vertical dovetail joint 54 in a rearward end, a semi-circular outwardly facing platform 58 on a bottom portion, a bulkhead 86, and a vertical dovetail joint 54 in a foreword end. The adapter 84 is united with the receiver portion 22 and mates with the dovetail joint and platform 58. When the locking wedge threaded fastener 64 enters the locking wedge bore 52 the receiver portion 22 and adapter 84 engage together in a rigid manner extending the length of the receiver portion 22.

(57) A connector 88 engages the adapter 84 together forming a combined set. The connector 88 incorporates the same vertical dovetail joint 54 in a rearward end and a semi-circular outwardly facing platform 58 on a bottom portion. The connector 88 interfaces with the adapter 84, and a second locking wedge threaded fastener 64 enters the adapter semi-circular outwardly facing platform 58 and engages a second locking wedge 50 the combined set is completed.

(58) An AR-15 type free float handguard 90, depicted in FIG. 34, is screwed onto the connector 88 with attachment means consisting of a barrel nut 92 and a castle nut 94, illustrated in FIGS. 34, 39, and 40 completing the second embodiment.

(59) The second embodiment also includes an alternate feature comprising the same adapter 84 and connector 88 which replaces the forestock portion 24 except a noise reduction suppressor 100 instead of the AR-15 type free float handguard 90. The suppressor is secured to the connector 88 which incorporates male threads and the suppressor 100 having mating female threads. The suppressor 100, which attenuates the sound, encloses the entire barrel 36a, and has only an exit opening in the front allowing the bullet to leave untouched.

(60) The third embodiment, illustrated in FIGS. 42-43, comprises a fore-end 20 consisting of a one piece combined receiver portion and forestock portion 96 which is attached to the buttstock 12 flanged stock bolt 18 with four buttstock threaded fasteners 30.

(61) The receiver portion has a cavity 32 forming a receiver bedding interface surface 34 which precludes peripheral interference. The receiver portion has a recoil lug pocket 40 with threaded fasteners engage a rifle action recoil lug. The buttstock, combined receiver portion and forestock portion have lightening areas 98 for reducing overall weight.

(62) It is preferred that the one piece combined receiver portion and forestock portion 96 is made of aluminum with an anodized finish, however it is anticipated that other materials may be employed, as are presently used in firearms, which include wood, epoxy laminated wood, polymer, fiberglass and formed steel sheet material.

(63) Other than the absence of the fore-end attaching components the remainder of the one piece stock 96 remains the identical to the preferred embodiment.

(64) While the invention has been described in complete detail and pictorially shown in the accompanying drawings, it is not to be limited to such details, since many changes and modifications may be made to the invention without departing from the spirit and scope thereof. Hence, it is described to cover any and all modifications and forms which may come within the language and scope of the appended claims.
