Cautious with high mounts needed - Leapers UTG 3-9x40mm Hunter Rifle Scope

I would suggest being cautious with the Picatinny mounts that worked quite well for my G-2 Whisper 177. However, I could not zero after many attempts! one-two inches low consistently. Armando has been great at helping me figure this out. I upgraded from a CenterPoint. What a big difference in both clarity as well as front and back focus adjustment settings, color Reticle, and 20-30 yards excellent! Now to zero, will be replacing the Picatinny mounts that I just put on, for high rings. Never simple.
The original rings had the front AO adjustment touching the stock!
