rear sight moving? I'll have to check into that.

I had good "luck" with a SAR-1 and a Romy G 86 build, as well as a milled arsenal.

all would make 2-3" groups at 100 Yards.

The ones with bad "luck" were a SAR-2, A SAIGA in 7.62, and my last 2 WASRS...but with an AK its really luck of the draw, need to scope in my WASR and see if that helps a bit.
