Help me pick my first long range optic. I putting together my first long range rifle. Tikka in a KRG Bravo chassis. I'm getting ready to buy my optic and have a few to choose from. I'm stuck between the Vortex PST Gen 2, Athlon Cronus BTR or buying a used 1st gen Razor all 3 are about the same money and I'm going MRad if that matters. I'm sure there is probably a thread that would help but I'm old and suck at the internet so any help would be appreciated.
