Shameless plug here, but if anyone has been waiting with baited breath. Just this afternoon we received a box from Hartford, and inside was 5 brand shiny new Colt piston ARs. They have the full monolithic rail uppers with flip up sights and MagPul collapsable buttstocks.
I don't know what they'll cost, we haven't invoiced them yet, but they will be in the system and on the rack come morning. So if you gotta have one I'd suggest being by the shop bright and early, as my guess is they won't be around long.
