Always been a fan of signature zee rings. Getting ready to try some for my RPR 338 lapua. Putting on a Sightron SIII 8-32x56 and from my measurements, it’s gonna be close with extra high rings as to whether it’ll clear the hand guard or not. I like the inserts so my next option is the XTR signature rings. They have the inserts too, but they’re aluminum. Anyone run aluminum rings on a magnum RPR? Any durability issues? The rail is aluminum already which I’m not crazy about but no one that I’ve found is making a steel rail for them yet. Thanks I’m advance for the input.
