a buttplate disposed along one of said opposing frame ends and extending approximately transverse said frame passage; and

,

a mounting rail disposed along said frame wall and including a first wall projecting from said frame wall and a plurality of mounting openings extending through said first wall.

22. A firearm buttstock according to claim 21, wherein mounting rail includes a second wall extending approximately transverse said first wall.

23. A firearm buttstock according to claim 21, wherein said plurality of mounting openings includes a series of openings disposed in a pattern along said first wall.

24. A firearm buttstock according to claim 23, wherein said pattern includes spacing said openings of said series of openings at substantially uniform intervals along said first wall.

25. A firearm buttstock according to claim 23, wherein said plurality of mounting openings includes a plurality of first substantially circular holes having a first size and a plurality of second substantially circular holes having a second size.

26. A firearm buttstock according to claim 21, wherein said buttstock frame includes a plane of symmetry and said first wall of said mounting rail extends from said frame wall symmetrically along said plane of symmetry.

27. A firearm buttstock according to claim 26, wherein said mounting rail includes a second wall and said second wall extends from said first wall symmetrically along said plane of symmetry.

28. A firearm buttstock according to claim 21, wherein said frame passage includes an upper curvilinear portion and a lower rectilinear portion, and said first wall extends from said frame wall from said lower rectilinear portion.

29. A firearm buttstock comprising:

a buttstock frame including a frame wall extending between opposing frame ends;

a mounting rail including a first wall disposed along said frame wall and including a plurality of first mounting openings extending therethrough;

a buttstock accessory including an accessory wall and a second mounting opening extending through said accessory wall, said buttstock accessory supported on said buttstock frame such that said accessory wall is disposed along said first wall of said mounting rail and said second mounting opening is at least partially aligned with one of said plurality of first mounting openings; and

,

a fastener extending at least partially through said second mounting opening.

30. A firearm buttstock according to claim 29, wherein at least a portion of said accessory wall includes a contoured exterior surface.

31. A firearm buttstock according to claim 29, wherein at least a portion of said accessory wall defines an accessory passage having an open end.

32. A firearm buttstock according to claim 31 further comprising a cap including a side wall receivable within said open end of said accessory passage.

33. A firearm buttstock according to claim 29, wherein said first wall of said mounting rail includes first and second sides and said buttstock accessory is a first buttstock accessory that includes a first accessory wall disposed along said first side, said firearm buttstock further comprising a second buttstock accessory supported on said buttstock frame and including a second accessory wall disposed along said second side of said first wall of said mounting rail.

34. A buttstock for an associated firearm having an associated receiver extension, said buttstock comprising:

a buttstock frame including a frame wall extending longitudinally between opposing first and second frame ends and at least partially defining a frame passage extending into said buttstock frame from said first frame end for receiving the associated receiver extension;

a buttplate disposed along said second frame end and extending approximately transverse said frame passage;

a mounting rail disposed along said buttstock frame and extending between said first and second frame ends, said mounting rail including a web portion extending from said frame wall, a flange portion extending approximately transverse said web portion, and a mounting opening extending through said web portion;

a buttstock accessory including an accessory wall and a mounting tab extending from said accessory wall with a tab opening hole extending through said mounting tab, said buttstock accessory positioned along said buttstock frame such that said mounting tab is in abutting engagement with said web portion of said mounting rail and said tab opening is aligned with mounting opening; and

,

a fastener extending through said tab opening and said mounting opening to at least partially secure said buttstock accessory on said buttstock frame.

35. A buttstock according to claim 34, wherein the associated receiver extension includes an associated retaining recess and one of said frame wall and said buttplate includes an access passage adjacent the associated retaining recess, said buttstock further comprising a retaining member engaging the associated retaining recess through said access passage to secure said buttstock frame on the associated receiver extension.

36. A buttstock according to claim 35, wherein said access passage extends through said frame wall adjacent said mounting rail and said web portion of said mounting rail includes a retainer opening at least partially receiving said retaining member.

37. A buttstock according to claim 36, wherein said retaining member is retractably supported on one of said buttstock frame or said mounting rail.

38. A buttstock according to claim 36, wherein said retaining member includes a base member and a pin member pivotally connected to said base member, and said retaining member is received within said retainer opening such that said base member engages said flange portion of said mounting rail.
