Don't have an AR, bought a 556 instead and have been very satisfied with it. Been thinking about buying a few more black rifles and am having trouble deciding how to proceed. The Del-Ton rifles seem to get reasonably good reviews and are available <$700 which seems like a heck of a bargain. Would kind of like to get another 556 (Commando model) but could get a couple of the Del-Ton rifles for that price.
