Dave, if you replace your Buckhorn sight with a Buffington sight, you'll have to make sure that your Rear Barrel Band (1884) has the correct groove milled out on it's top to accomadate the knob that tightens down and secures the elevation slide in position. Only the Buffingtone sights required these special bands. DO NOT groove one out yourself. They are available from trapdoor parts dealers. The 1st rear sight for the 1873 rifles and carbines had a stepped sight base that predatd the so called 1877 which was different and which predated the so called 1879 or Buckhorn. Then came the 1884 or Buffingtone sight. Buffington, by the way, was I believe the man who developed the 1901 Krag sight and the 1905 rear sight on the 1903 Springfield. Someone please corect me if I'm off on this. Anyway, Buffington's sights were of a superior design that allowed for much greater accuracy that went beyond what the average soldier was capable of unless he was properly trained to use them to full advantage. They were truly a rifleman's target sight. Of course they were wonderfully adaptable for picking off men and horses at great distances under the right conditions. Look at the graduations of the Buffington soght and look at the Peep sight and field sight and how they can be adjusted in very fine increments. They were the finest sight of their time and are still fantsticly incredible and superior to pretty much any modern rear sight except for some rear target sights that are also adjustable in fine increments. Even the 1905 rear sight on the 1903 Springfield wasn't accurately incremented past 1000 yards because Springfield by then no longer had a firng range over 1,000 yards, so anything further out, up to 2700 yards or so, was calculated on paper. It was discovered later that these paper calculations were not accurate, but the design stuck and was never changed or updated. Not so of the 1884 Buffington sight. It was accurate all the way out to it's full graduation if the correctly loaded rounds were used utilizing the correct alloy of 500 grain bullet and the correct load of powder. An off the shelf factory box of Winchester 300 grain bullet ammo will not print on a distant target according to the graduations of a Buffington sight. The correct loads will have to be used. The same goes for the earlier sights that were designed to use rounds with a 405 grain bullet of the correct alloy. Sorry for going on and on...I'll stop now.
