US Patent 7793454 Bipod firearm support

A bipod for supporting the forward portion of a firearm includes a clamp portion, a pivot body and a pair of leg assemblies. The clamp portion is adapted for clamping to a firearm and is pivotably mounted to the pivot body for pivoting about a vertical axis and a longitudinal axis. The pivot body includes a pair of leg mounting surfaces. A pair of leg assemblies are pivotably mounted to the mounting surfaces of the pivot block so that each leg assembly may be pivoted about an axis that is generally normal to the mounting surface and such that each leg assembly can be adjustably positioned in one of at least two positions.
