A bipod leg deployment assembly comprising: a housing; a leg housing; a leg assembly having a deployed position and a stowed position, these two positions having an arcuate separation of at least 45°; a leg deployment pivot axis around which the leg assembly rotates when moved from the deployed position to the stowed position; a bipod leg deployment button arranged near, but not coincident with the leg deployment pivot axis, and biased outward from the housing, the bipod leg deployment button comprising: an elongated and cylindrical cross section split into at least two lengths (172, 176), the lengths (172, 176) extending along a longitudinal axis of the bipod leg deployment button; a first length of the lengths (172, 176) being a conical frustum with sides angled from the longitudinal axis by an angle selected from the range including and extending between 0° and 30°, and at least a first diameter (D 3) at a narrowest end of the conical frustum; a second length of the lengths (172, 176) having a second diameter (D 4), smaller than the first diameter (D 3); and wherein the leg assembly includes at least two conical cutouts (182, 180) proximal the leg deployment pivot axis, and wherein the bipod leg deployment button is shaped to engage with one of these conical cutouts (182, 180) when the leg assembly is in the deployed position and is shaped to engage with the other of these conical cutouts (182, 180) when the leg assembly is in the stowed position. a housing; a leg housing; a leg assembly having a deployed position and a stowed position, these two positions having an arcuate separation of at least 45°; a leg deployment pivot axis around which the leg assembly rotates when moved from the deployed position to the stowed position; a bipod leg deployment button arranged near, but not coincident with the leg deployment pivot axis, and biased outward from the housing, the bipod leg deployment button comprising: an elongated and cylindrical cross section split into at least two lengths (172, 176), the lengths (172, 176) extending along a longitudinal axis of the bipod leg deployment button; a first length of the lengths (172, 176) being a conical frustum with sides angled from the longitudinal axis by an angle selected from the range including and extending between 0° and 30°, and at least a first diameter (D 3) at a narrowest end of the conical frustum; a second length of the lengths (172, 176) having a second diameter (D 4), smaller than the first diameter (D 3); and wherein the leg assembly includes at least two conical cutouts (182, 180) proximal the leg deployment pivot axis, and wherein the bipod leg deployment button is shaped to engage with one of these conical cutouts (182, 180) when the leg assembly is in the deployed position and is shaped to engage with the other of these conical cutouts (182, 180) when the leg assembly is in the stowed position. an elongated and cylindrical cross section split into at least two lengths (172, 176), the lengths (172, 176) extending along a longitudinal axis of the bipod leg deployment button; a first length of the lengths (172, 176) being a conical frustum with sides angled from the longitudinal axis by an angle selected from the range including and extending between 0° and 30°, and at least a first diameter (D 3) at a narrowest end of the conical frustum; a second length of the lengths (172, 176) having a second diameter (D 4), smaller than the first diameter (D 3); and wherein the leg assembly includes at least two conical cutouts (182, 180) proximal the leg deployment pivot axis, and wherein the bipod leg deployment button is shaped to engage with one of these conical cutouts (182, 180) when the leg assembly is in the deployed position and is shaped to engage with the other of these conical cutouts (182, 180) when the leg assembly is in the stowed position.
