What is there to say?

What is there to say? It's a scope mount, quite solid once installed as per leupold direction. Torque everything down give it a nod, that baby ain't goin anywhere.

About Leupold Base

FEATURED REVIEWS

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.

Perfect fit!
