The Columbia Precision Tang Peep Sight is a precision machined instrument designed to fit Winchester rifles of both current and discontinued manufacture. It will also fit some modern manufacture guns which are replicas or reproductions of the Winchester arms, such as Browning, Rossi and Uberti (and, yes, the Columbia Precision sight may be supplied with a base to accommodate the thumb safety). As well as these arms, the sight will also fit the most configurations of the classic Sharps rifles. With minor gunsmith work, blank bases are available to fit Marlins, Ballards and a variety of similar guns.
