Picked this sight up and mounted it on my Marlin 1895 Cowboy. Bulls eye fiber optic sight.
Really gives you a wide field of view. Only don't be mislead by the pic. The inner ring is not as sharp as it appears in the pic but is more of a blurred ring. Still easy to center the front sight for fine shooting. Also the bridge is not quite high enough. I was on the last notch before I got my ammo hitting at the correct elevation. I solved that problem by drilling an tapping the rear sight leaf and put in a 8-32 set screw to raise and lower the sight using the bridge as a buffer between the screw and barrel to keep from scratching the barrel. But this may be caused by my load (35 gr of H4198 and 405 gr. cast bullet) because I had the same trouble with the stock buckhorn sight. I may just drill and tap that one too. I am still working on a load for this rifle and just loaded the same bullets up with 50 gr of IMR3031.
