I recently picked up a used mid length from a gunshow (armalite brand), man this thing is a shooter, only one thing about it though....the hand guards are a bit different them some of the others I have seen. they are bigger around at the end by the front site, I guess you could say they are straight and big like a free float tube. I like them myself, would like to find some in green. guess I will call armalite and find out how much these in green cost.....
