    Swap between Buffington and ramp backsights?

    OK Trapdoor fans, don't scream! This is a serious question: I would like to buy a Trapdoor, with the Buffington sight, as they quite simply outshoot most other military BP cartridge rifles, especially with aged eyeballs. But some competitions insist on open sights and do not permit rifles with Buffington sights to compete in the military class. The answer would be to buy a Buffington trapdoor and swap the backsight temporarily as needed. But this is only realistic if the swap is a simple screw off/screw on alteration.

    So: do the two types of backsight have the same fixing hole spacing, or would the ramp backsight have to be altered to fit in place of the Buffington?
    (I know that it doesn't work the other way around, because of the notch in the barrel band.)

    For those who are worried by this idea: my rifles are tools, mostly hard-used tools, not museum showpieces.

    IIRC the spacing and hole size are the same for all of the models of 'trapdoor' Springfield rifle sights. The screws may be of different length and head size.

    The rear sight hole spacing, location relative to receiver, and threading are IDENTICAL for ALL .45 caliber trapdoors, period. The screws do change, and the lower band is different as to top profile. However, all of the components are readily available at a reasonable price, and may be swapped in less time than in took me to type this. So, "no worries"!

    Thanks for the answers. So now all I have to do is find an affordable Trapdoor in good shooting condition. That might take a while...

    Patrick - Some of the 1873 Springfield rear-sight screws are of the "un-slotted" type. These are trickier to remove than the later screws, with screw-driver slots.

    ALL of the "ramp" type sights (M1873, M1877, M1879) were originally shipped from the Armory with slotless screws, except for the long-range rifles which had a slightly different (more pronounced dome) form to the head. Any other such sights now found with slotted screws had them changed - most by sources unknown. The Buffington was the only TD sight originally issued with slotted screws. A number of slotted screws on ramp sights will show signs off being hand-slotted. Slotless screws offered for sale today frequently have little stab marks at the edge where they were grabbed with a sharp-edged tool to extract them in a hurry, or where the preferred collet tool proved ineffective, when replacing sights en masse.

    What a strange idea! Slotless screws! I cannot think of another example, and can only surmise that someone thought it was a clever trick to prevent non-armory personnel from removing the sights. Like the "reversed" screw heads on the Enfield No. 4 foresight, which, as Peter Laidlericon informs us, were often enough replaced with normal screws by the armorers if the original was FUBARed!

    Patrick - that was the stated reason.
