Our Scope Ring Alignment Tool will enable any shooter to properly align and install both 30mm and one inch scope rings from any manufacturer in any style. Use the Alignment Tool before lapping, to align the scope tube in the rings. This Alignment tool goes beyond the traditional pointed rod style tools in that the alignment rods are adjustable within the two tool bodies after the bodies are mounted in the scope rings - no more loosening the rings several times to adjust the rod point lengths. The rods are held in the tool bodies by precision machined collets which exactly center anodized aluminum with cylinder sizes to fit 1 inch rings and 30mm rings. This tool is easy to use, and makes correct scope mounting much easier.
