I used Talley, one piece (base/ring) mounts, to mount this Nikon on my Savage model 10 chambered in .243
This Combo is a tack driver-solid and dependable.
A guy could spend a lot more for rifle glass, and not do desernably better.
Pros: Crystal clear optics; good contrasted rectile; and easy focus eyepiece.
