Is there any way to self repair a scope which runs out of windage clicks before it reaches the bullseye at 25 yards? It is not a rings issue nor an alignment issue with a particular rifle. Using a different set of rings or change rifles and the same problem exists. The scope was made in China with a lifetime warranty and naturally the importer who sold it out of business. The only way to get the scope centered in it's windage range is to shim the rear ring 1mm which is very thick. Not being a scope guru is there a way to work on the scope to correct this windage misalignment? There are windage adjustble rings, but they are worth more than the scope. Any scope experts out there who have repaired a scope with a similar issue?
