Adjustable butt stock assembly
First Claim
1. An adjustable butt stock assembly, comprising:
- a buffer stem carrying a rack of transverse teeth;
a butt stock, said butt stock having a forward end and an aft end and a first longitudinal hole therethrough dimensioned to receive said buffer stem;
an over-center lock assembly attached to said butt stock and having an aft end and a fore end, a locked and an unlocked orientation, said over-center lock assembly havinga lever with a fore end and an opposing aft end, said fore end of said lever being pivotally attached to said fore end of said over-center lock assembly; and
a toothed foot carried by said over-center lock assembly, said toothed foot also having transverse teeth,said butt stock being fixed with respect to said buffer stem when said aft end of said lever is pivoted upward to bring said toothed foot of said over-center lock assembly into engagement with said transverse teeth of said rack of teeth and adjustable with respect to said buffer stem when said aft end of said lever is pivoted downward to bring said toothed foot out of engagement with said transverse teeth of said rack of teeth.

Abstract
A semi-infinitely-adjustable butt stock assembly. A butt stock is slidably affixed to a buffer stem. An over-center lock is attached to the butt stock adjacent to the buffer stem. The user can disengage the over-center lock from the buffer stem by rotating a lever thereby permitting the longitudinal position of the butt stock to be adjusted relative to the buffer plate. To secure the butt stock at the desired position, the user rotates the lever in the opposite direction causing the over-center lock to re-engage the buffer stem. A cheek rest overlaying the butt stock and biased forward with respect thereto is adjustable vertically with respect to the butt stock by manually moving the cheek rest aft, adjusting it vertically, and releasing the cheek rest.

11. An adjustable butt stock assembly, comprising:
-
a buffer stem; a butt stock, said butt stock having a forward end and an aft end and two opposing sides therebetween, said sides having opposing posts extending outward therefrom and opposing traps extending outward therefrom;
said butt stock having a first longitudinal hole therethrough dimensioned to receive said buffer stem so that said butt stock slides over said buffer stem;a saddle-shaped cheek rest dimensioned to overlay said butt stock, said cheek rest having two substantially parallel spaced apart sides joined by a curved top, said sides having opposing forward tabs extending inward therefrom and dimensioned to engage said traps of said butt stock and opposing aft tabs extending inward therefrom dimensioned to engage said posts of said butt stock; a biasing saddle, said biasing saddle longitudinally slidably attached to said butt stock and vertically slidably attached to said cheek rest, said biasing saddle and said cheek rest biased forward with respect to said butt stock by a spring bearing on said butt stock so that said forward tabs of said cheek rest engage said traps of said butt stock and said aft tabs of said cheek rest engage said posts of said butt stock and so that a user can adjust the height of said cheek rest with respect to said butt stock by manually pulling said cheek rest aft with respect to said butt stock thereby disengaging said forward tabs of said cheek rest from said traps of said butt stock and said aft tabs of said cheek rest from said posts of said butt stock, repositioning vertically said cheek rest with respect to said butt stock, and releasing said cheek rest; an over-center lock attached to said butt stock and having a locked and an unlocked orientation, said over-center lock engaging said buffer stem when in said locked orientation and not engaging said buffer stem when in said unlocked orientation so that said butt stock is fixed with respect to said buffer stem when said over-center lock is locked and longitudinally slidably adjustable with respect to said buffer stem when said over-center lock is in said unlocked orientation.

12. An adjustable butt stock assembly, comprising:
-
a buffer stem; a butt stock, said butt stock having a forward end and an aft end and two opposing sides therebetween, said forward end having a pair of opposing transverse posts extending outward therefrom, said aft end of said butt stock having a pair a pair of opposing transverse posts extending outward therefrom, said butt stock having a first longitudinal hole therethrough dimensioned to receive said buffer stem so that said butt stock slides over said buffer stem; a saddle-shaped cheek rest dimensioned to overlay said butt stock, said cheek rest having a forward end, an aft end, and two substantially parallel spaced apart sides joined by a curved top, said forward end having a pair of opposing detent channels extending inward therefrom and dimensioned to engage said posts of said forward end of said butt stock, said aft end having a pair of opposing detent channels extending inward therefrom and dimensioned to engage said posts of said aft end of said butt stock, all of said detent channels extending vertically and having a forward and aft zigzag shape; a biasing saddle, said biasing saddle longitudinally slidably attached to said butt stock and vertically slidably attached to said cheek rest, said biasing saddle and said cheek rest biased forward with respect to said butt stock by a spring bearing on said butt stock so that said posts of said butt stock reside in aft portions of said detent channels and so that a user can adjust the height of said cheek rest with respect to said butt stock by manually pulling said cheek rest aft with respect to said butt stock thereby removing said posts of said butt stock to move out of said aft sections of said detent channels and then releasing said cheek rest so that said posts of said butt stock are repositioned in adjacent aft portions of said detent channels of said cheek rest; an over-center lock attached to said butt stock and having a locked and an unlocked orientation, said over-center lock engaging said buffer stem when in said locked orientation and not engaging said buffer stem when in said unlocked orientation so that said butt stock is fixed with respect to said buffer stem when said over-center lock is locked and longitudinally slidably adjustable with respect to said buffer stem when said over-center lock is in said unlocked orientation. - View Dependent Claims (13, 14, 15, 16)
