Pulsar Rubber Eye Piece Replacement 

This magnetic rubber eyecup, made by Pulsar, is designed for the Thermion, Talion, and Digex scopes. It is the same eyecup included with these optics from the factory, providing the necessary eye relief to prevent splashback from the display at night. It is compatible with all Thermions (XM, XQ, XP, XG, and DUO models), as well as Talion XQ and XG models, and the Digex series of scopes.
