Anyone got a reliable scope mounting system whereby I can take a Vortex Diamondback 3-9x40 scope on and off my 336SS thereby using iron sites when I choose and putting scope back on when I feel like it and still have it hold zero? Seems like a lot to ask, I know, but was hoping some of you had some experience trying this out. I hunt Maine where most shots are under 100 yards. But my aging eyes make think I should have the ability to scope the gun at will when longer shots might be viable. Thanks in advance for any input.
