Hello Everyone,

Does anyone have any ideas of who might have made bases for the 1903 Springfield rifle [not A3 or A4] that have hole distances of .860" for front and .490" for rear?

I have a Remington 1903 [not an A3] that was previously drilled/tapped for scope bases by a different owner. I bought it without bases, but filler screws in those spots.

I intended to shoot it with iron sights but, well- I can't see the front sight.
My close vision is shot [over 50], and my astigmatism makes lining thin lines up challenging on a good day.

I want to mount a 4x scope, just so I can use this and not be frustrated every time I aim it at the target.

However, I need help with scope bases.

Mine is drilled with .860" between the holes on the front base [similar to Weaver #46 base], but has .490" between holes on the rear base [no Weaver base with that distance on their chart].

Weaver 2 piece bases [#54 and #55] are supposed to have .504" spacing on both bases.

Unfortunately, using the #46 base for the front doesn't seem likely, as it uses a different diameter and thickness than the #55 [front], while the rear isn't matched anywhere.


Any advice would be appreciated. I like this old rifle, but want to be able to actually use it and have a hope of hitting something- instead of just looking at it.

Thank you
