I am looking for a scope for my Tx200 to shoot bench rest from 25 to 50 meters. Also wanting to use on air arms s500 out to 100 yds. Is there a scope with paralax adjustment for 25 or less - 100 yds. I need very fine crosshairs or etched glass. etched galss preferred. Recommendations please . Willing to spend $500-$600 bucks.
