4 of 5 Nice product July 18, 2023
: David from PA, USA  
Seems to be high quality and well built. I don’t have the parts for the rest of my rifle yet, so I can’t try it out to give a full review.

5 of 5 Looks and Feels Great May 18, 2022
: from Port Saint Lucie, FL United States  
I received my order in a timely manner. The item was securely packaged. I noticed the barrel was a little dirty so I will need to clean it before shooting but the upper feels and looks really nice.

5 of 5 Awesome as always! February 4, 2021
: Alan Claypoole from Stoneboro, PA United States  
Fit and finish are amazing! Couldn't ask for more. Shipping was fast, despite Covid-19 slowing everyone down. MAS is and will be my go- to for all things AR related.

5 of 5 Ordered a 16'' upper for my AR pistol conversion November 20, 2020
: Craig Smith from Meridian, ID United States  
With the current climate with the ATF coming for braced AR pistols. I needed a 16'' upper to convert my pistol to a rifle, do to case law stating this is legal. Mas Defense had a great price, so I took a chance. I received it 9/18 the fitment is great, so far I am pleased. I will take it to the desert this weekend and send some rounds down range to re-zero my optic.

5 of 5 Great company, product and customer service October 23, 2020
: jayson tomer from pomona, CA United States  
Have purchased several orders from this company and have received exactly what I expected and the timely manner expected and any questions I had concerning my order were promptly replied to. Been shopping around for other sites trying to piece together a build or two and so far this has been my best experience from an online vendor. definitely five star rating

5 of 5 Good Quality upper October 23, 2020
: KURTIS STALEY from Delaware  
I like the uppers MAS puts together. They are assembled so they run out of the box and you will never have to change a thing. Perfect upper for a do all carbine set-up.
