I dont know if this has been previously discussed, as I was unaware of this until today. Apparently the market is being flooded with fake Leupold Mark 4's... I found one on a local classifieds page today. The guy sent me pics of what appeared to be a 4-12X40 Mark 4. Upon looking it up via Leupolds webpage I discoverd that Mark 4's come 3.5-10 and 4.50-14 power... I then seen the warning issued about the fake scopes. Just wanted to give anyone who was unaware a heads up.
