Warne Maximas fixed and QD are my first choice for all Weaver style rings.
Or, if you want to spend less than $20, buy a set of medium height Durasight DS300 rings or B-Square Sport Utility rings. I have used both of these make/model of rings without any problems, but I would always (ALWAYS) opt for Warnes on my top/1st tier rifles.
I have B-Square Sport Utility rings on 7 of my 9 RAR-Ps, all with 10x40, 4-12x40, or 4-16x42 scopes installed. I upgraded to Warne Maximas on the 223 and 6.5 Creedmoor RAR-Ps for the rifles that I leave in the safe at our condo in Bethlehem, NH.
260Remguy, With the Warne Maximas on your Predators that have 40mm objectives, are you using low or medium rings?
You obviously like the Predator!
This is my first one. First impression is good. Appears well made, light, nice trigger, and bolt is a lot smoother than I expected.
