I had a SIG 556R and I liked the way it shot. Heard people say "Don't shoot steel ammo because...(insert whatever here)." So I went directly to the source and got an AK. I also thought the 556R was front heavy compared to the AK, although I had the "SWAT version" with the quadrails. But a nice shooter nonetheless, when I ran brass through it, I like the cheap ammo though.
