5 of 5 Awesome product!! February 8, 2024
: Jason W. from AL United States  
Let’s just say this product is awesome! First off shipping was fast. I ordered may upper I think Tuesday and it came in Friday. Secondly their customer service is second to none. I had some address issues and called MAS defense and they were friendly and really awesome to talk to and fixed my order with no issues. Lastly everything about my upper is nice and married tightly with my lower. All came pre-assembled and ready to-go if that might be a question. Overall Awesome product and company. Will order again from them.

5 of 5 7.5 inch 556 upper January 6, 2024
: Shawn Lachance from Middleburg, FL United States  
This is 5th upper I have purchased from Mas Defense ( 3 - 556's & 2 - 300BO's).  All of them are superb quality fit & finish. I purchased this upper for a SBR build. I have attached a DA Sierra 5, still loud.. lol. Great little truck gun. I have recommend MD to friends & I know one of them have purchased 2 of their 9mm uppers. My buddy was pleasantly surprised for quality & value for the money.  My next upper is going to a 13.7" FDE upper & 12 FDE sQUADRon handguard.

5 of 5 Very nice upper!! November 20, 2020
: 135 from MO United States  
The attention to detail and quality is second to none. This complete upper looks amazing, I am an operator, and this is a very nice complete upper that looks great on an SBR or as an AR pistol.
Very happy,
135

5 of 5 beautiful work June 27, 2020
: Jeremy Miller from Ridge, NY United States  
Upon receiving my upper from MAS defense I was very pleased to see the quality that was put into the craftsmanship of my upper receiver. Shipping and handling was fast and tracking was made available immediately. I would love to buy another upper from MAS defense soon as their stock is replenished
