Lyman's No. 2 Tang Sight is a flip, peep sight mounted to lever action rifles to make those long shots. It provides a clear view of the target and front sight and can be used when the light is too dim for other sights. The "peep" is also a great help to sharpen the front sight. This model is compatible with Marlin 336, 1894, 1895, 30 rifles. Adapter base may require drilling and tapping into tang of rifle.
