Found this used at a local shop for $499, just need to get the right forward assist and flash hider to get it right. I know the barrel isn't quite right, it a Gov. Profile chromed lined in 5.56 not .223. I know the barrel is suppose to be slimmer. I will be picking up 5 steel 20rd mags to go with it as well and a hard case. On a side note. The rear sight has two setting just like the a2 or a3, but on this a1 they seem to be the same. What's up with that.
