I have no problem with Optilocks except that the 2 piece are way too heavy for what is sold as a lightweight gun. Why would I want to use rings and bases as heavy as some scopes on a light weight rifle?
The Optilock ringmount is fine but will only accommodate about a 42mm objective.
Leupold makes even lighter ringmounts but they need to be at least half way down the dovetail to grip so scope tube length VS eye relief could be a problem with some action lengths and some scopes.
Talley makes bases and rings.
Near MFG makes a picatinny rail
Some others I can't think of right now too.
