We have 3 axis combo's, we left the scope that came with it on one, it shoots 1.5'' at 100 yards but the scope is not great, cross-hairs are thick and clarity poor. I have a feeling optics limit that rifle. With decent scopes the other 2 shoot under 1'' groups at 100 yards fairly consistently. Pretty accurate guns for $250. I did adjust the triggers which helps a lot in shooting better groups, the triggers were super heavy initially. You may want to try tightening up the bases/ rings too, i found they all came loose which would wreck groups.
