1. A firearm stock system, comprising:
a butt stock;
a hinge having at least a first hinge knuckle, at least a second hinge knuckle, and a hinge pin pivotally connecting the hinge knuckles, the first hinge knuckle adapted to be connected to a firearm receiver and the second hinge knuckle connected to the butt stock whereby the butt stock is pivotable between an extended position and a folded position; and
a latch mechanism operable to selectively lock the butt stock in the extended position, the latch mechanism comprising:
a socket adapted to be connected to the receiver, the socket having a cam surface; and
a latch member rotatably connected to the butt stock, the latch member having a latch hook and a latch lever, the latch hook engaging the cam surface as the latch lever is rotated from an open position to a locked position,
the latch hook and cam surface configured such that rotating the latch lever from the open position to the locked position draws a rear portion of the receiver and a forward portion of the butt stock into firm abutting engagement with one another to prevent mechanical play between the receiver and the buttstock.
