I've had 3 Sightrons on 3 rifles , S111 6 x 24 LRMOA for 6 years with no problems . Some day i'll upgrade but for now i can't find a reason . I bought zero stops and tactical turrets for them , they track well and no need of warranty work . One each on a .223 , .308 and .338LM .
if you dont mind sharing. Where did you get the stops and how much were they?
