Service was fantastic, with ultra-quick shipping. The upper looks and works fantastic! I would definitely buy from MAS Defense again, and would recommend them to anyone!

Fantastic upper and company

Great upper. Barrel length is exactly what I wanted and looks great all hardware is tight and secured. My upper has a few blems but the great team at mas was super quick about resolving the issue. The option to upgrade the receiver colors and also gas system on the website is quick and easy to use and provides a custom touch without ever having to pick up a wrench. Definitely going to return to purchase more parts as time rolls on with this company
