I had a Valmet over and under. A .243 over a 12 gauge. There was a flip up sight on the rib. Even with iron sights it was extraordinariy accurate. No easy way to mount a scope.
Another one of those I should have kept. Metal work was first class but the walnut stock was just good. Several small mistakes in the checkering.
It would shoot like a house on fire tho.
Just an odd platform.
Love It!
