Great point Bullit.The particular type of gun in question is one that requires the toughness to deal with the double recoil of a NP/NP2 or heavy Springer type... Hence the question about airgun scopes, or scopes rated to handle "airgun" recoil. I am reading that with so many scopes used for this purpose, individual scopes among the same model perform or not. many forum posts talk of having owned 4 of X scope, with 2 working well, and two failing early on.
