They’re are as good as any other rings at holding a scope straight on your rifle. What makes them the best is two bolts with the same fastener and the same torque do do the same job as other rings with four plus bolts and two or more types and torque specs. They make mounting a scope well as easy as it can be.
Once you get your scope, set it for eye relief and level torque it down! You don't have to worry about it moving as you tighten. My second one is in the mail!
I liked my first set so much I now own four. Sold 4 sets of seekins to replace with these. For the small price difference the scope mounting ease makes it worth the money. Seekins would always move around while tightening the 4 screws
