Rifle Scopes Will these rings fit?

[NYSShooter]

Hey guys, brand new here and looking for a little advice!

I've just purchased a Savage 10FCP McMillan(A5) and a few trimmings to go along with it. On top will sit a 20moa rail, and an optic with a 50mm objective lens diameter.

Looking around, I'm thinking I may purchase IOR heavy duty 30mm rings. The low rings say they're .250''. That seems pretty small to me. What are your thoughts? Will it fit?

And if I do end up going with IOR, do you suggest lapping?

Thanks in advance!

I would say no, this is my basis, Badgers low ring is .823 and Leupolds is .84, now these work with a 40MM scope but would not be enough for a 50MM unless your base is real high.

Do the rings need to be lapped? will depend on if they are true or not.

It looks like IOR measures from the top of the rail to the bottom of the scope tube. Fifteen mm = .591" + .250" = .841" rail to tube C/L.

Badger std rings are .823" and work fine mounting a Mk4 6.5-20 x 50 onto Rem 5R with a 20 MOA rail. Enough clearence for the Butler Creek caps.

Lapping is never a bad idea.

You know, I was wondering if the measured differently from other manufacturers. Thanks for noting that in your post.

Perhaps I'll be ok with the low rings. I definitely want the OL as close to the barrel as possible.

If it helps, the optic is a Bushnell Elite Tac 6500 6-24x50.

Can lapping change the clearance specifications inside the rings so that it wont properly clamp to the scope tube? I work in an automotive facility that houses a state of the art body shop.. If I cant find the right size tube and some good compound, I'm in trouble. But again, I want to make sure it's OK to do, and in fact suggested.


Btw what do you guys think of IOR rings?

Midway has Wheeler lapping & alignment kits on sale now for $37.99. That's a pretty good deal.

Using the correct diameter lapping bar you won't take off enough material to change the clearence enough to make a difference. That is unless you spend several days lapping.
