Leupold scope base for a 1903-A3 sporter

[JRuby]

Does anyone have the hole spacing for the 1903-A3 one piece base from Leupold - Part # 49997. I picked up a project rifle that has been drilled and tapped and wish to replace the scope mount.

Good question for sure....
I'd bet @MountainBear might know.

I have a whole bunch of sporter scope bases, but oddly enough, no Leupold bases…

I suspect someone at Leupold will know.

Send them an email.

Talked to Brownells nice people
the answer is

• Ken: the front 2 holes are .860" and from the center hole to the rear is 4.100"
• for the leupold standard one piece 1903A3 scope base #49997

If it turns out not to be the spacing for a Leupold mount, let me know and I will check the bases I have laying around!

With my micrometer the numbers match.
