I just had a 5.56 upper built how I wanted with the options I wanted plus a lower with everything to complete the rifle by Brett at Ironworks tactical for well under the 1500.00 mark. It has an awesome barrel on it from AR Performance. I ordered the lower and put together myself, Brett does not sale complete rifles. If you cant put the lower together yourself, most any gunsmith could do it for you for a nominal fee. I got the Aero precision lower. Its a mil spec lower. I put a red dot aimpoint on it that I already had, but can tell you that I would have had PLENTY of cash left over to purchase a good quality scope if I had a 1500.00 limit. Check them out, great quality stuff.
