RE: extreme sniper or copper johns?
I had CJ sights and tried several others. I'm now back to nothing but CJs. They're simple, solid, and backed by a great bunch of people. With the big pin guard I can use a large peep, for better light transmission. And the large pin guard gives a very good sized field of view, even close up. BTW, the .029 pins are brighter, and better for hunting, than the .019s, IMO.
