Athlon Talos BTR 4-14×44 with the APLR2 first focal plane MIL reticle. Would be hard to find an airgun rated scope for less with all of these features. The things I would want for sure are a MIL based Christmas tree reticle, first focal plane and, and parallax adjustment with a minimum around 10yd or 15yd. This scope has all of these, and 4-14x is a good/versatile magnification range too.
If you have never experienced a FFP scope with matching hold over reticle, then you are missing out. It will change how you shoot and your idea of precision shooting.
