I put the reflex sight on mine because I wanted to use the gun in Zambia -- and still will, if my buddies and I can ever coordinate our schedules, so I wanted something that aimed very fast, and was good close up -- the other thing about them is it takes practice to use them properly -- I can only shoot mine well free hand, and w. both eyes open -- not match quality, but at 80 yds, I can shoot about a 2.5" to 3" group w. factory remington ammo -- considerably larger than acceptable w. good iron sights/scope, but much faster to use, at least for me.
But your right, at about 100 yards, that 4.3 MOA makes the gun pretty difficult to use on paper -- still works fine on animals -- but 150+ and it's time to go get out one of the scoped bolt actions.
