Need resource for repairing Ajack scope

I have a 2.5X70 Ajack scope marked 2782. I cannot seem to get it adjusted. The reproduction mount is firmly attached to the receiver - no play. Elevation changes are unpredictable. Sometimes one click makes a small change, then other times one click makes enormous changes. Windage changes are also inconsistent, but not as bad as elevation changes. Any advice will be appreciated. --TIA

Ask Brian at BDL for the address of his friend who fixes Lymans. The ajak is a simple scope so should be simple to fix
