Re: Question about quick change scope rings?
I´d go with some quality picatinny rail and rings. Detach rings just mean, in my opinon, that there is a lever in the base of the rings so that you dont need a key to unscrew the base screws/nut. At the end of the day it is just a matter of having the little tool with you. UNless you go with the swing base european type ( ie apel), but I dont trust them as much as a picat or similar non-rotational system.
My opinion is that in any case, you better check POI after installing the scope or changing it. Good mounts will hold almost same POi.
For lever type rings, I´d go with a pair of Talley.
