Hey everyone first post. I recently bought a used mini14 198 series. I bought a scope and Weaver rings, the type that allow use of the iron sights. After mounting the scope it is noticeably not straight with the rifle. Question is has anyone had this problem? Did I get bad rings? Btw this is a 70 dollar Walmart special scope, also the mini is a ranch rifle with built-in scope mounts and pop up sights. Any help is much appreciated. -Drew
