A3 scope mount

[Banjobend]

Hello, I recently inherited a 1903a3. It has been drilled and tapped to mount a scope. I bought the Leupold mount hoping it would be the right bolt pattern, but it's way off.

Anyone know of a mount with this spacing?

4.625 rear to middle hole
5.125 rear to front hole

I hope those numbers you listed aren't in inches. Never seen a 1903A3. Would you mind posting pictures?

They are in inches. Center to center.

I would suggest you try Weaver #59 (rear) and #45 (front). They may be a bit hard to find at this late date, but they were a popular mount system in the 60's when the DCM sold a lot of A3's. The #45 should be easy to find since it's used on Mauser rifles: The #59--not as easy! I'd try the #45 first to see if the hole spacing mates; if it doesn't, the #59 is moot.

I found a #45 base in my "stuff" and the hole spacing is exactly .500" and, from your measurements, it appears that's what you have.

Ebay has lots of 'em--both numbers. And, of course, rings for Weaver bases are everywhere.

Oh sweet. Thanks for the info! Looks like those are cheap and available from Midway. I'll try them.

These worked perfectly, thank you for the help.

I am not sure if you have any questions
