Good light upper!
August 5, 2019
: Eric from Newark, NJ United States
Nice upper. Fairly light weight, good tolerances and put together well. I’m only 1,440 rounds in but I like it. I would buy another one of these.

Super nice Barreled Upper
March 14, 2019
: Andrew Turner from HYATTSVILLE, MD United States
Super quick shipping. Had a question after ordering and customer service responded quickly and answered the question in one email concisely. Very happy with this upper for my AR Pistol, looking forward to ordering a longer barreled upper for a rifle build I have done. 100% will do business with MAS Defense again.

11.5" MAS Upper in 5.56
March 9, 2019
: VanguardSHD
For the money, it's a solid, slim-lined work of art. I got it in M-Lok because ...hype matters. Everything is seated flush and correct. Right out of the box it's ready for your mall ninja equipment and hitting the range. Only thing I didn't like was that I needed to stop my day in order to be home and sign for the item from UPS. Overall satisfied to the fullest extent. Buy yours now!

A great upper
March 7, 2019
: Andrew Wallace from Gulf Breeze, FL United States
The quality is top notch. A friend recommended me to your company, and I am glad he did. You have a customer for a long time. Looks great, fired a couple hundred rounds through it this last weekend... Great all around.

Great product
December 25, 2018
: Mitch from Cincinnati, OH United States
I couldn't be happier with my order from MAS! The entire upper is far sturdier and better looking than the current photos suggest, and has been 100% reliable thus far. While accuracy has yet to be tested, I have little doubt that it will deliver the goods. I remain truly impressed with both the company and my new upper. Will be buying from MAS again!

Best 11.5 buy on the market
December 9, 2018
: Erik from PA United States
Great upper and barrel for an unbeatable price. Even better looking in person than online this upper is the best value 11.5 on the market today without a doubt. This is my 3rd upper from MAS and each one better than the last, 10/10.

Great Barreled Upper
September 23, 2018
: Paul Graybeal from Mountain City, TN United States
The quality of this product is too notch. The MAS Defense upper fit my Spikes Lower perfectly. The slim flash can sets off this pistol build. I have not had an opportunity to put any rounds through it yet, but can't wait to see how it performs.

Great Upper
September 15, 2018
: Paul G. from Tennessee
Purchased this barreled upper on 9\10 and received on 9\14. It is exactly what I wanted to complete a pistol build. The MAS Defense Forged Upper perfectly fit my Spikes Lower, and the assembly of this upper is spot on. Would not hesitate to order from MAS Defense again.
