Will Medium height rings work with a 40 mm Rifle Scope or can you get away with Low?

[KnightExtreme]

Wondering what height Rings would be required for a 40 mm Rifle Scope, medium or low? Trying to help select the right 1's for a friend as we rarely buy new rifle scopes which his GF is looking to buy with the rings with the right height rings as a Xmas Gift?

Depends entirely on what its going on, but for a bolt action with a factory stock low would be normal height for a 40-42mm scope. I’ve even used extra lows a couple times. Mediums will be too high on most factory stocks.

Depends on the rifle. I have a Mauser action that needs mediums, but my Tikkas all use lows.

Rem 700 BDL .06 SS, maybe for a Burris Fullfield 3-9 x 40 with Burris Signature Scope Rings. Was not aware Different Rifles had :difference Clearances needs?
He has an old Simmons but wants to upgrade his scope and use Burris Signature Rings with the inserts.
Thanks for the replies.
