Very solid upper and well built. Just the right weight for what I was after.

had heard great things about MAS Defense products so I figured I would give them a try. Ordered this upper and found out for myself that MAS provides great products for a great price. Customer service was excellent and shipping was quick. I highly recommend this company and will use them again
