The 'clean' installation of aluminum or brass shotgun sights has always been one of the bug-a-boos of the gunsmithing profession. The Shotgun Sight Installer exactly fills the need for a truly precision instrument with which to install a shotgun bead without a mark - satisfying even the most particular gun man. The holding jaws are internally ground and lapped to give maximum holding surface on the globe of the sight without marring or damaging the metal. Priced at a level any gunsmith can afford, yet will give a lifetime of service.
