Just got a 5R in 308, and with the IRS I am tapped out for a bit.I do however have a Weaver V16 variable 4x16x42 in the gun locker. The Weaver has around a 50" adjustment range at 100 yards I think. So as a temporary solution would this work? It would be for paper punching only.I'd like to go 500+yards out with it but don't know if that will work.So a 20 moa base seems likely but I don't know. So will it work ? What moa base height do I need? Any and all comments are greatly appreciated!
