I forgot to specify, the upper I bought was from BOTACH and appeared to a factory upper by itself. It came in the blue white/blue box, in it's birth bag inside, along with instructions manual and a little accessory pack. I have a thread a little while ago with photos. Colt 11.5" barrel **** Update with photos****, those appear to be similar to those offered previously by Colt and now offered by the other major venders, Midway, Brownells... I was going to upload the photos but was having trouble with Photobucket. I imagine those are come from the factory as is... As for the other stripped parts, I imagine they are parted out from complete guns.
