I recently purchased a Ventilator 150 and have a optimizer that I plan on mounting on it. I am trying to figure out which scope would be the best. I would like to target shoot from 20-100 yards and want to be as accurate as possible. I been trying to do some research. So far I've read not to use a regular rifle scope because the recoil is different but an air rifle scope would be fine. I've also read that I should choose one with an adjustable parallax or have the scope customize with a parallax at 40 or 50 yards. I know the scope will need to have a lot of adjustments available as the HHA raises the scope 1/2" higher. I am just looking for a regular reticle or something like the leapold firedot. Any suggestions? Curious to read what others are using. I previously owned a RDT 165 with an HHA and a 3-9x50 Barska and had no issues.
