I have always heard parallax is a a problem with airgun shooting and it why you need a airgun scope. well for that last 6 years i have been using a center fire rifle scope and i have never seen this parallax beside at very close range(10 yards or less in dark deep woods in open ground i have really never seen it) and even then it's not a problem. I have my 760 and 66 cromman sighted in for 30 yards dead on and most of my shots are 15-45 yards in urban to flat sandy breach areas both day and night.
