Abstract

A collapsible firearm stock system is generally provided and preferably includes a shoulder stock system adapted to receive a buttstock thereon, and a locking linkage having a first linkage portion, a second linkage portion, and a hinge pin operatively uniting the first and said second linkage portions. One of the linkage portions is carried by the shoulder stock assembly so as to define a terminal end therefore, the other of the linkage portions being adapted to be carried by a firearm. Each of the linkage portions are adapted so as to automatically unite in locking engagement upon axial alignment of the shoulder stock assembly with the firearm about the hinge pin.

Claims

1-48. -48. (canceled)

49. A firearm stock assembly comprising a hinge pin, and first and second operatively linked hinge portions, said second hinge portion biasingly received upon said hinge pin, translation of said second hinge portion upon said hinge pin permitting rotation thereof between first and second interference arrangements for said first and second hinge portions, said first interference arrangement characterized by a first interference resistance, said second interference arrangement characterized by a second interference resistance, said first interference resistance being less than said second interference resistance.

50. A firearm stock assembly comprising a hinge pin, and first and second operatively linked hinge portions, said second hinge portion biasingly supported upon said hinge pin in furtherance of self registration of select elements of said first and second hinge portions, translation of said second hinge portion upon said hinge pin overcoming a self registration of select elements of said first and second hinge portions so as to thereby permit rotation of said second hinge portion about said hinge pin.

51. The assembly of claim 50 further comprising a shoulder stock extending from said second hinge portion.

52. The assembly of claim 50 further comprising a variably positionable shoulder stock extending and extendable from said second hinge portion.

53. The assembly of claim 50 wherein self registration of select elements of said first and second hinge portions comprises a first self registration of first select elements of said first and second hinge portions and a second self registration of second select elements of said first and second hinge portions.

54. The assembly of claim 50 wherein self registration of select elements of said first and second hinge portions prohibits rotation of said second hinge potion about said hinge pin.

55. The assembly of claim 54 wherein self registration of select elements of said first and second hinge portions comprises a latched interface of a latch of said second hinge portion and a latch receiving structure of said first hinge portion.

56. The assembly of claim 50 wherein self registration of select elements of said first and second hinge portions impedes rotation of said second hinge potion about said hinge pin.

57. The assembly of claim 56 wherein self registration of select elements of said first and second hinge portions comprises a hindered interface of a block of said second hinge portion and a stage of said first hinge portion.

58. The assembly of claim 50 wherein said self registration of select elements of said first and second hinge portions comprises a latched registration.

59. The assembly of claim 50 wherein rotation of said second hinge portion upon said hinge pin via grasping a free end portion of the assembly alters a further self registration of select elements of said first and second hinge portions in furtherance of uniting said first and second hinge portions.
