Abstract

A firearm buttstock includes a buttstock body having first, second and third passages. A transfer member is received in the second passage and a retaining member is received in the third passage. A firearm is also disclosed that has a receiver extension. The firearm buttstock can be supported on the firearm such that the receiver extension is received within the first passage. A method of assembling a firearm buttstock assembly is also included.

A buttstock assembly according to claim 5, wherein said third passage wall includes a third portion defining a top wall of said third passage and a fourth portion defining a bottom wall of said third passage, said first and second side walls of said third passage extending widthwise between said first and second sides of said buttstock body and heightwise between said top and bottom walls of said third passage.

7. A buttstock assembly according to claim 5, wherein said first and second side walls of said third passage are approximately planar, and said outer side wall of said transfer member includes at least one portion that is approximately planar and is positioned to abuttingly engage said one of said first and second side walls of said third passage.

8. A buttstock assembly according to claim 7, wherein said outer side wall of said transfer member includes a first wall portion defining a first side wall oriented toward said first side wall of said third passage and a second wall portion defining a second side wall oriented toward said second side wall of said third passage.

9. A buttstock assembly according to claim 1, wherein said retaining member includes a first outer surface disposed along said first end, a second outer surface disposed toward said second end and spaced radially-inwardly from said first outer surface such that a shoulder wall is defined between said first and second outer surfaces.

10. A buttstock assembly according to claim 9 further comprising a biasing element operatively disposed between said shoulder of said retaining member and said buttstock body, said biasing element operative to urge said first end of said retaining member toward said first passage.

11. A buttstock assembly according to claim 10 further comprising a retraction member operatively connected to said retaining member along said second end thereof.

12. A buttstock assembly according to claim 11, wherein said buttstock body includes a fourth passage wall at least partially defining a fourth passage extending through said top portion and in approximate alignment with said second passage.

13. A firearm comprising:

a receiver extension including a first end operatively engaging a firearm receiver and a second end spaced longitudinally from said first end; and

,

a buttstock assembly operatively engaging said receiver extension for displacement therealong between a first position disposed toward said first end of said receiver extension and a second position spaced longitudinally from said first position toward said second end of said receiver extension, said buttstock assembly including;

a buttstock body including a first passage extending longitudinally from a first end of said buttstock body toward a second end of said buttstock body, a second passage extending approximately transverse to said first passage and a third passage extending approximately transverse to said first and second passages, said third passage extending through a portion of said buttstock body in communication with said first and second passages;

a transfer member at least partially received in said second passage, said transfer member including an inner side wall at least partially defining an opening extending therethrough and an outer side wall extending along a peripheral portion of said transfer member, said transfer member positioned within said second passage such that said opening is in approximate alignment with said third passage and said outer side wall is in abutting engagement with said buttstock body;

a retaining member extending between a first end and a second end spaced from said first end, said retaining member at least partially received within said third passage and extending through said opening in said transfer member such that said first end of said retaining member projects at least partially into said first passage to operatively engage said receiver extension;

18. A method according to claim 17 further comprising providing a biasing member and installing said first biasing member at least partially into said second passage in abutting engagement between said transfer member and said buttstock body.

19. A method according to claim 17, wherein providing a buttstock body in a) includes providing a fourth opening disposed in approximate alignment with said third opening and extending through said buttstock body on an opposing side of said first passage from said third passage, and installing said retaining member in e) includes inserting said retaining member into said third passage through said fourth passage.
