Sights should fit without excess force, and if excess force is required, sight fitment is not as it should be. New sights should be able to slide above a third of the way into the dovetail by hand properly fitted. Please follow all manufacturer’s installation instructions and these guidelines when using this tool.For any questions or assistance in installing sights, please contact the sight manufacturer.We cannot be held liable for any damage or injury caused by using the tool you will receive.
