RE: ? For the guys using copper john
I own the CJ DeadNuts 2 Comp and WVSportsman is right you cannot get zero pin gap on that sight. While the design of having staggered pins on separate adjustment rods should allow it the design of the pins themselves prevents it. The reach a point where when they get thicker toward the housing those part touch and don't allow any more adjustment. You can get them fairly close, but not zero pin gap.
