Claim:
1. A multi-axis firearm foregrip comprising: a mount engageable to a firearm in at least one fixed position; a handle adjacent the mount, the handle having a gripping portion and a handle axis; a ball-and-socket joint engaging the handle to the mount, the joint having a socket in the mount and a ball in the socket and being configured for handle movement relative to the mount to a plurality of different axial orientations in plural planes with the axes of all axial orientations intersecting one another, the ball supporting the handle with the handle axis extending out from the ball and the handle being capable of swiveling motion relative to the mount to the different axial orientations, each axial orientation having the same center of rotation within the ball; and a movement restrictor which acts on the joint to hold the handle in a selected axial orientation, the movement restrictor including an outwardly-spreadable segment in the ball, a spreader within the ball, and a pin movable in the ball in threaded engagement with the handle joining the spreader to the handle such that rotation of the handle in a first direction results in application of a force on the pin and spreader which causes the spreader to spread the segment outward to hold the ball against the socket with the handle at the selected axial orientation and rotation of the handle in an opposite direction quickly releases the force allowing the ball to swivel within the socket and the handle to be repositioned at another axial orientation.
