Scope bases

[wch]

Need to know manufacturer and product number of bases that will fit a round barrel 1 inch in circumference; predrilled and tapped, 5/8 inches center-to-center.
If hole spacing is not relevant or available I will redrill and tap.
Thanks for your help.

Are you looking for a 1913 or Weaver type base?
Basically anything that fits a 1 inch round receiver like a Ruger Mk2 pistol would work.

Weaver type will do, and thank you.

Brownells sell a blank weaver rail 12" in length the can be cut to length drilled and counter bored for what ever you want. not sure what all radiuoses are offered though.

Thanks, gents: on the advice of Weaver's tech service I bought a couple of #17 bases.

I'll bet the OP meant Diameter...

[wch]

Yes, diameter.

I have had good luck making stuff fit the right radius, buy something close, then some sticky sandpaper on the barrel, sand it to fit.

Here's a chart of Weaver base specs. I've found it helpful in the past. Thanks Brownells!

I don't see anything with a .625 hole spacing. #76 might work, only has 1 hole, add the other where needed.
