Used to be only 2 or 3 good scope brands available . Now I'm overwhelmed with the different scope brands and functionality. I'm wanting to upgrade scopes on this machine. It has a $100 solar scope and factory trigger. With this combination I can cover 3 shots with a quarter at 100 yards. I just upgraded the trigger and going to upgrade the scope, but don't know where to start. Maybe $500.00 budget. I'd like to do some long range shooting. (400yards). Any recommendations?
