The bottom of the forend has an elongate slot. A bipod having a plurality of legs is pivotally attached at one end of the legs to the bottom of the forend. The bipod has an unfolded position in which an opposing end of the legs extends downwards beyond the exterior contour of the forend. The bipod has a folded position in which the opposing end of the legs is received within the elongate slot with the legs substantially within the exterior contour of the forend. The opposing end of the legs may each have a notch. There may be a latch having a cam surface that is spring biased to protrude into the slot. The notches may receive the cam surface when the bipod is in the folded position, thereby releasably securing the opposing end of the legs within the slot. ## Claims ### Claim 1 A firearm stock comprising: a body including a forend having an exterior contour and a bottom; the bottom of the forend having an elongate slot; a bipod having a plurality of legs pivotally attached at one end of the legs to the bottom of the forend; the bipod having an unfolded position in which an opposing end of the legs extends downwards beyond the exterior contour of the forend; and the bipod having a folded position in which the opposing end of the legs is received within the elongate slot with the legs substantially within the exterior contour of the forend. ### Claim 2 (depends on 1) The firearm stock of claim 1 further comprising: the opposing end of the legs each having a notch; a latch having a cam surface that is spring biased to protrude into the slot; and wherein the notches receive the cam surface when the bipod is in the folded position, thereby releasably securing the opposing end of the legs within the slot. ### Claim 3 (depends on 2) The firearm stock of claim 2 further comprising: a button attached to the bottom of the forend; the button being spring biased to protrude into the slot; wherein the button is displaced from the slot by the opposing end of the legs when the bipod is in the folded position, which compresses the spring; and wherein the spring decompresses and urges the button downwards, which displaces the opposing end of the legs from the slot when the cam surface of the latch is withdrawn from the notches in the legs. ### Claim 4 (depends on 1) The firearm stock of claim 1 further comprising: a block attached to the bottom of the forend within the slot; the block having a central bore that receives an axle having opposing ends; the end of the legs attached to the bottom of the forend each defining a major bore that receives one of the opposing ends of the axle; the end of the legs attached to the bottom of the forend each defining opposed minor bores that communicate with the major bore; each opposing end of the axle defining a bore; and wherein the minor bores of a selected leg are axially registered with a selected axle bore so that a fastener received within the minor bores of a selected leg and the selected axle bore secures the selected leg to a selected end of the axle; and wherein the legs can pivot about both the axle and the fasteners. ### Claim 5 (depends on 4) The firearm stock of claim 4 wherein the minor bores, axle bores, and fasteners are positioned perpendicularly to the axle. ### Claim 6 (depends on 4) The firearm stock of claim 4 further comprising: a spring having opposed ends; the end of the legs attached to the bottom of the forend each defining opposed apertures that receive one of the opposed ends of the spring; and wherein the spring biases the legs to pivot outwards about the fasteners. ### Claim 7 (depends on 4) The firearm stock of claim 4 wherein the end of the legs attached to the bottom of the forend is received within the central bore of the block when the bipod is in the unfolded position. ### Claim 8 (depends on 6) The firearm stock of claim 6 further comprising the elongate slot having a widened portion on either side that receives a portion of the end of the legs pivotally attached at one end to the bottom of the forend when the bipod is in the unfolded position. ### Claim 9 (depends on 8) The firearm stock of claim 8 further comprising: the opposing and of the legs each forming and angled pad; and wherein the widened portion of the slot is angled such that the angled pads are parallel to the bottom of the forend when the bipod is in the unfolded position. ### Claim 10 (depends on 8) The firearm stock of claim 8 wherein the end of the legs pivotally attached to the bottom of the forend are closely held within the elongate slot, thereby compressing the spring, as the bipod pivots about the axle until the end of the legs pivotally attached to the bottom of the forend reaches the widened portions, at which point the spring decompresses and urges the end of the legs pivotally attached to the bottom of the forend to pivot about the fasteners into the widened portions. ### Claim 11 (depends on 1) The firearm stock of claim 1 wherein the end of the legs pivotally attached to the bottom of the forend are pivotally attached within the elongate slot. ### Claim 12 (depends on 1) The firearm stock of claim 1 further comprising: the legs having a flat forward facing surface; and the flat forward facing surface being substantially flush with the exterior contour of the forend when the bipod is in the folded position. ### Claim 13 (depends on 12) The firearm stock of claim 12 further comprising the bottom of the forend being a flat surface.
