Sweet looking piece, but I'm stuck on the shoot 5.56 not .223! Now if it shot .223, but not 5.56 then that would make since. OOOhhh well every firearm is different. I have a brand new ACOG Amazon.com: Acog 4 X 32 Scope Dual Illuminated 4.0 Moa Crosshair .223 Ballistic Reticle, Red: Sports & Outdoors that I'll be willing to part with for 1400 if you know anyone interested. It's the brown verision but brand new!
