Adjustable firearm stock

Abstract

An adjustable stock comprises a frame and a housing that slides telescopingly with respect to the frame between at least two configurations: a shortened configuration and a lengthened configuration. Preferably there is at least one configuration of intermediate length. To permit the adjustment of the stock, a lever arm, biased in a locking position, is pressed, whereupon it unlocks the housing from the frame and allows the user to slide the housing with respect to the frame from one configuration to another. The lever arm has a projection on the end that is either seated in one of several recesses in the housing, thereby locking the frame to the housing, or slidable within a channel formed in the housing and running from one recess to another.

1 . A stock for a firearm, said stock comprising: 
 a frame;    a housing slidably carried by said frame between a shortened configuration and a lengthened configuration;    a locking lever pivotally carried by said housing and pivotable between at least one locking position and an unlocking position, said locking lever locking said frame to said housing when said locking lever is in said at least one locking position; and    means for urging said locking lever into said at least one locking position, said urging means limiting movement of said locking lever from said at least one locking position to said unlocking position.    
   
   
       2 . The stock as recited in  claim 1 , wherein said locking lever is adapted to lock said frame to said housing in said shortened configuration and in said lengthened configuration.  
   
   
       3 . The stock as recited in  claim 1 , wherein said frame has two recesses formed therein and said locking lever carries a projection, each recess of said two recesses dimensioned for receiving said projection, said locking lever locking said frame to said housing when said projection is received within said each recess.  
   
   
       4 . The stock as recited in  claim 1 , wherein said urging means further comprises: 
 a pin;    a spring; and    a butt plate, said spring urging said locking lever into said locking position and said pin limiting movement of said locking lever when said pin meets said butt plate.    
   
   
       5 . The stock as recited in  claim 1 , wherein said locking lever has a first end and an opposing second end, said first end extending outside of said housing, said second end being inside said housing.  
   
   
       6 . The stock as recited in  claim 5 , wherein said second end carries a projection and said frame has at least two recesses, said projection of said locking lever being received by either recess of said at least two recesses when said frame is locked to said housing.  
   
   
       7 . The stock as recited in  claim 6 , wherein said frame has a channel formed therein and running between said at least two recesses, and wherein said projection moves within said channel when said frame is moving with respect to said housing.
