Default Removing 1903 rear sight sleeve?

Picked up a 1903 drill rifle. Got it all apart but canít figure out how to remove the rear sight barrel sleeve? Donít see an obvious pin. Barrel date is 1918. How hard is/was it pressed on? Have a lead on a replacement barrel, but needs the sight sleeve. Any suggestions would be greatly appreciated!

This same subject was discussed on another thread recently.

Basically, you should remove the barrel from the receiver first. This will probably require some grinding on the tack weld before you put it in the barrel vise and wrench tool assembly (available from CMP).

The rear sight collar is pinned in two places. One pin is inserted on the bottom of the collar at a 90 degree angle to the barrel. You might notice some grinder marks which were parked or blued over where the ends of the pin were ground down. The second pin is on the right side of the barrel and is in line with the barrel between the barrel and the collar. You can only see it when the barrel has been removed.

Remove the forward pin with a pin punch, then use a piece of pipe or socket large enough to miss the barrel, but contact the sight collar. Drive the whole collar forward by striking the pipe/socket with a mallet.

Note, some drill rifles have holes burned through the collar which welds it to the barrel. Be sure to do some grinding on that "wound" before attempting to drive the sight collar forward.

The sight collar is relatively soft metal and if you attempt to drive it off using a wooden or metal piece (like a screwdriver) you will damage it and the sight won't fit into it.
