I have an A2 upper, 11.5" heavy barrel with perm. 5.5" flashider, pre-ban, chrome lined. Never fired. Comes without bolt, carrier or charging handle. I bought it many years ago and never finished the project. It's either Model 1 or M&A, not sure. Asking $275 plus $10 shipping.
Picture on request. Be patient, I only check the board every other day.
Thanks for looking, Tom.
