US Patent 10234232 Bipod base

A bipod base consisting of a rail clamp, a first quick-release, a ball joint, first and housing clamps, first and second spherical bushings and a second quick-release. When the second quick-release is loosened, the rail clamp is allowed for 360-degree angular position adjustment with the ball of the ball joint relative to the first and second spherical bushings and the first and second housing clamps. After adjustment, the second quick release handle is biased to fasten tight the first and second housing clamps in locking the first and second spherical bushings that are kept in surface contact with the ball of the ball joint.
