Gamo Down And To The Right 🤨

Hello All,
I’m new to this group and to air guns. I have an old Gamo Outback Maxxim that came with a Gamo 4x32 scope. My problem is, no matter what I do the POI always ends up being down and to the right from my POA. So….I bought a pair of WEAVER Sure Grip Windage 1-Inch X-High Adjustable Rings. They arrive today. I hope I’m headed in the right direction. I really need to get this rifle to shoot straight.
I would welcome any helpful input on this matter.
Thanks, OldBilly.
