Well, 100-0 still beats 99-9x.
I mounted my A4 with a Vortex Viper 1-4, Yankee Hill riser with medium Leopold rings. That combination allows the same head position I had when using the A2 receiver. Nose on the charge handle. I found head position seems harder to maintain with the scope. Iron sight apertures, being small, guide the eye better to center then the larger scope ocular. A suggestion I'm trying is to put a 1/4 inch hole in a front scope cover. It is supposed to reduce potential parallax errors. Still experimenting.
