I got ahold of a RPR Rimfire and I am trying to decide the glass. I am thinking of going with a 20 mil rail, and I would like a scope for it with mil/mil turrets and a nice mil reticle. FFP I think is what I want also. Parallax adjustment. I like Vortex, Burris, Nikon, weaver scopes. All mine have been good. Haven't had good luck with PA or BSA(reticle started to rotate on first mag on a charger.) I am wanting something to practice with for long range. I am wanting to practice mil adjustments and hold over. Please let me know if I'm going about this wrong, still new to a lot of this stuff.
