I have for sale a factory NIB 14.5 Troy upper receiver. Gas system is mid length. Item number is SUPG-CL0-14BT-00. I bought 2 of these on closeout, the one I run shoots great but I have my eye on another item and this one is up for sale. Upper is NIB and unfired. Did not come with a BCG. Google the item number for more specs. I’m asking $450. Price is firm. Cash, PayPal, or Venmo. I’m happy to answer any questions. My number is 8709260312, call or text. Thanks for looking, Matt
