Scope mounting questions

[Flynt]

I'm trying to mount a Burris Short Mag scope on a Marlin 336. The eye relief is so generous that I'd like to move the scope farther forward than the mount permits. (However, I don't want to mount it on the barrel, scout style.) I see two options: 1) use extension rings (which I've never done before), or 2) cut an extra notch in a Leupold one-piece rail mount.

A couple of questions:

A. Are extension rings as stable as standard rings? (B-Square makes a set of low extension rings that might do the trick.)

B. Is it possible to cut the notches in the rail mount with only hand tools? Or is more precision required, such as making sure the new notches are square and aligned?

Thanks.

You can probably cut them by hand with a round chainsaw file.

However, the cross-slots are also the recoil lugs for the scope ring clamp-bolts, so they need to be full bearing when the rings are slid foreword against them and tightened.

Extension rings work just fine.

I would use extension rings, they are just as good as a comparable vertical ring, and a great deal easier to do.

How good are B-Square rings? They're really cheap, about $13.00 a pair, which would tend to scare me off, but they're the only ones that seem to come in a "low" configuration.

Extension rings are as good as standard rings, given equal material, design and manufacturer.

B. Is it possible to cut the notches in the rail mount with only hand tools? Or is more precision required, such as making sure the new notches are square and aligned?

Is it possible, well... anything is possible. Would it be sufficient enough to preform correctly, I seriously doubt it.
Find yourself a machine shop, have them mill the extra slot, it should not cost more than $20 and that's a expensive figure, probably more like $10?
Sweet talk them!

The slot HAS to be square with the rail, attempting to do this by hand....
