Original and reproduction 1901 sight-screws show up on Epay and S&S Firearms (Glendale, N.Y.).

Hand-Guards are prone to crack if snapped on and off the barrel.

If a hand-guard is not installed on a barrel, it is under spring tension.
It should be stored with a Quarter twisted into the rear-spring and a Penny or Nickel twisted into the front spring, to counteract the tension.

Best way to remove and install a Krag hand-guard is to take off rear-sight and take barrel-action out of stock.

The hand-guard can be slipped toward muzzle, where it will be loose and easy to remove.
It can be put back on, at the muzzle area, and slipped up the taper into place.
