Abstract: An apparatus is disclosed for aligning gun sights wherein the rifle is mounted on a gun-receiving member that pivots relative to a fixed base. A spring is fixed between the gun-receiving member and base for absorbing both the horizontal and vertical components of the recoil of the gun when it is fired, the spring being positioned on the side of the pivot adjacent the butt-receiving end of the gun-receiving member. An internally threaded hole is provided through the gun-receiving member on the side of the pivot opposite the spring, and an externally threaded rod, which is rotatably mounted to the base, is disposed through the aperture for selectively tilting the gun-receiving member relative to the base to help align the gun sight with a target. Once the gun sight and target are aligned, the gun is fired and the recoil is absorbed by the spring as the gun-receiving member pivots relative to the base.
