I an going to be getting a new scope for my sniper rifle, I really don't much like ording thangs off the internet so at my local wal-mart store they sell snopes for airsoft and bb guns, the only brand they have is daisy. My uncle told me that he had a daisy scope on his 22 and the scope won't never stay ajusted the way he wanted it, it always seemed to shoot downward or upward or right or left. My question is is daisy scopes good? Do they stay the way you want them? Are they even worth getting?
