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. Was this review helpful to you?

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. Was this review helpful to you?

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. Was this review helpful to you?

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. Was this review helpful to you?

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.

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. Was this review helpful to you?
