5 of 5 Purchased this upper a few weeks ago. August 4, 2019
: Nick U  
Haven't shot it yet since I'm waiting for a few more parts for my 300blk build. But the upper receiver right out of the box was perfect. No blemishes or scratches. It was packaged securely. Customer service was awesome, sent then an email regarding some questions I had about the warranty and some specs of the barrel that were not mentioned in the description and they got back to me relatively quickly. Will update the review one I shoot the thing. But if it's all good will definitely buy from MAS Defense again.
