Lyman has recreated the sight that the Lyman Gun Sight Company was founded on in 1878. Like the original, the No. 2 features height index marks on the aperture post, maximum elevation of .800" for long range shooting. It comes with both .093 quick sighting hunting aperture and .040 large disc target aperture. Also included is a replacement rear stock screw and front tang screw. The No. 2 Tang Sight’s greater sight radius means as much as 32% greater inherent accuracy at 100 yards. It provides a clear view of target and front sight and can be used when the light is too dim for other sights. Can be adapted to other lever actions, plus some single shot rifles. Made to fit the Marlin 336, 3895 or 30 series. No. 502100
