I have owned this upper for several months and I have only put 40 rounds through it. No issues, and very accurate, but I have no need for it.
It is a 14.7'' PSA upper, with a pinned A2 flash hider, M4 midlength hand guards, vltor mod 4 gun fighter charging handle, 1:7 twist, chrome lined and daniel defense a1.5 buis + complete BCG/bolt (PSA)
Not a scratch or sign of wear on it. $850 shipped + 4% for paypal. I will also accept paypal gift, chase quickpay, or MO (no fees for these).
