Spot on; establishes multiple scope

Spot on; establishes multiple scope accommodations, enables efficient action engagement of ammo, and efficient action discharge of casings. It's simply one of the biggest no brainers in the history of man kind. Thank you, Leupold.

Rock solid base as expected

By Rateoftwist

I have used the mark 4 mounts on several rifles, and have never had any problems with the base or rings through many years of service. If you are looking for a solid base for hunting or long range you cannot go wrong with mark 4 bases. I also appreciate the MOA cant for the long range applications.
