Some Weaver mounts, that go on the #2 Base, appear to be taller and allow the Ocular-Lens Housing on a 1 inch scope to clear the issue bolt-sleeve.

Pictured is a 1 inch Weaver detachable side-mount, (model #49350). It is holding a K-3 Weaver. This 'rig' clears the bolt-sleeve, but, does not allow function of the issue Krag safety-lever.
A 'Krag' Buehler safety-lever would allow safety function.

The 1" Weaver K-3 pictured is a lot brighter than 3/4 inch Weaver Scopes.

It is also cheaper than the 3/4" and 7/8" Scopes, sought by Springfield model 1903/A4 'Sniper Rifle' fanciers.
