Collapsible Stock Assembly
First Claim
1. A collapsible stock assembly for a firearm, the assembly comprising:
- a stock body having a buffer tube passage defined therein extending in an axial direction, a buffer tube insertion opening being defined on a forward end of the stock body to allow insertion of a rear end of a firearm buffer tube therein in the axial direction, the buffer tube passage being dimensioned to slidably accommodate at least a portion of the buffer tube therein, the stock body also defining an adjustment slit extending axially rearwards from the buffer tube insertion opening and communicating with a forward portion of buffer tube passage and extending radially outward therefrom;
a first adjustment mechanism carried by the stock body, and including a buffer tube engagement element displaceable into the buffer tube passage and a first operating lever operable to selectively position the buffer tube engagement element; and
a second adjustment mechanism carried by the stock body, and including a second operating lever having a stock body engagement portion, the second operating lever operable to selectively engage the stock body with the stock body engagement portion to compress the adjustment slit.

Abstract
A collapsible stock assembly for a firearm includes a stock body defining a buffer tube passage for slidably accommodating a firearm buffer tube therein. An adjustment slit communicates with the buffer tube passage along a forward portion thereof. A first adjustment mechanism canied by the stock body includes a buffer tube engagement element that can extend into the buffer tube passage and is selectively positionable by a first operating lever. A second operating mechanism includes a second operating lever that is operable to selectively compress the adjustment slit. Disengaging the first adjustment mechanism automatically disengages the second adjustment mechanism. Excessive force on the stock in several embodiments automatically disengages both adjustment mechanisms and minimizes damage to stock assembly and/or buffer tube.

25. A collapsible stock assembly for a firearm, the assembly comprising;
-
a stock body defining a buffer tube passage extending in an axial direction therein, and a buffer tube insertion opening on a forward end of the stock body to allow insertion of a rear end of a firearm buffer tube therein in the axial direction, the buffer tube passage being dimensioned to slidably accommodate at least a portion of the buffer tube therein, an engagement element channel extending radially outward from the buffer tube passage, at least one contoured engagement surface, and an adjustment slit extending axially rearwards from the buffer tube insertion opening, communicating with a forward portion of buffer tube passage and extending radially outward therefrom, and a first adjustment mechanism including; a buffer tube engagement element slidably arranged in the engagement element channel, an engagement element biasing mechanism arranged in the engagement element channel and biasing the buffer tube engagement into the buffer tube passage, and a first operating lever mounted to the stock body and operable to urge the buffer tube engagement element out of the buffer tube passage; and a second adjustment mechanism including; at least one engagement tooth slidably overlying the at least one contoured engagement surface, and a second operating lever mounted to the stock body and carrying the at least one engagement tooth, the second operating lever being operable to move the at least one engagement tooth over the at least one contoured engagement surface to adjust compression of the adjustment slit. - View Dependent Claims (26, 27)
