Re: Gen IV IORs
I did some research on the Generation IV IORs. The fellow that I purchased my Gen II and Gen III IOR scopes from says the Generation IV IORs are proving to be recoil resistant now, having been in use for the past 24 months. So the weight of the evidence is that the Gen IV IORs are good to go.
IORs have a good warranty. But it's still a hassle to have to be shipping scopes back and forth. Perhaps those issues are all history with the Gen IVs.
