5 of 5 Just what I wanted September 3, 2021
: Brian Kliem from Spring, TX United States  
This is the upper receiver that I purchased from MAS DEFENSE and I love what I got. Once more of the upper receivers come back in stock I will definitely be purchasing a third one for my AR-15 rifle. They have a great selection and great choices for upgrades. Great response time for receiving my receiver, which I was happy about. Great customer service kept me updated with any changes which is one thing I look for in a company.

5 of 5 Beautiful Upper April 7, 2021
: Johnny B from Eagle Pass, TX United States  
So I went with an 11.5 with a 12.62 handguard and a flashcan.. First thing I did was put 200 rounds through it. Upper functioned flawlessly and looks great doing it. It was surprisingly lightweight and I'm excited to put it through it's pace.

5 of 5 Great Value March 27, 2021
: Thomas Shaver from Ranson, WV United States  
Haven’t shot it yet but looks just as pictured/described. Great value for the money. It was hard to find a reasonably priced upper anywhere and you all shipped super quick. Definitely happy!

5 of 5 Exceptional product June 15, 2020
: Jonathan Howard from Easley, SC United States  
So I decided I wanted to build an ar pistol and I located the lower I wanted but I was considering multiple options for the upper receiver.  Buddy of mine told me about masdefense so I checked them out.  I love the fit and finish of this receiver.  No flaws on the product, good quality barrel and I love the style of the handrail.  Matched this with a nickel boron bolt and an ambidextrous charging handle.   I’ll be back for my next build.
