without naming the manufacturer of this scope I'm trying to find out from the forum when do you call it a day with a scope manufacturer? .i bought a scope over a year and a half ago from this manufacturer as I already have 3 from the same people and they are perfect. This is a top of the range scope and their dearest model , I have sent it back again , this being the third time , the first time it had a fault where it was not holding POA , it came back to me with a note saying they could find no fault, even though they had not correctly put the scope back together correctly after inspection. I sent it back again so they could fix their own fault and they returned it to me saying that they fixed the problem they had made. Once again I mounted the scope , checking all screws to base, screws on mounts , torqued etc, and once again it still didn't hold POA. I have returned it now for the 3 rd time after a year and half of pain and disappointment not to mention the cost of ammo checking the scope. I have spoken to the manufacturer several times to express my disappointment and dissatisfaction and have requested a new scope but there answer is we do not replace scopes . I have told them that this scope has neve functioned properly from new. Do I have to do through this agony again or is there something else I can do ? Please don't tell me to sell it off once it gets back because I wouldn't want to inflict this crap on anyone.
