So, my brain just went to a real odd place just now. I was thinking about getting a Elcan 3.4X for my AR10. They can be found reasonably and I really really like how they felt on a gun I was playing with. I also think it would be great for hunting on the west side where I dont often shoot more than a hundred yards. So I want one of those for sure. But I also like shooting at 300-500 yards or so and think I need a little more magnification. Could I throw a swing away magnifier on it? I know my FOV would go to hell but for target practicing I could make do. Am I out of my mind?
