EXCELLENCE! March 25, 2018 : Preston C   I ordered this upper assembly on 3/16/18. It arrived on 3/19/18. The shipping was super fast. The upper and the hand guard are aligned perfectly and the product was in excellent condition. I ordered it with the MAS upper and chrome moly barrel. It mated to my scorpion armament lower and has no gaps and is nice and tight. The feed ramps are nice and smooth. I shot 500 rounds thru it yesterd and had absolutely no problems. My groupings we're nice and tight and I rapid fired a 60 round magpul drum with out gloves and the hand guard barely even heated up. With the amazing quality of this product and support fast shipping coupled with the unbeatable prices, I can't justify ever needing to buy an upper assembly from another company. If you aren't sure about this purchase, I can assure you it is won that you will never regret. Was this review helpful to you?

10.5 5.56 4150V M4 Melonite Pistol upper February 20, 2017 : Kyle J   If you're on the fence about ordering from MAS Defense don't be, first off I had my order at my house in less than a week. It looks great, the fit and finish is good, the melonite on the barrel is great. I took it to the range and ran 180 rounds through it flawlessly. Accuracy is great 1.5'' groups with Holosun 2 MOA Red Dot. I couldn't be any happeier. Thank you Mas Defense for having a quality product at a great price! Was this review helpful to you?

10.5 pistol upper SS 1:8 wylde August 22, 2016 : phili R   This is my first upper from MAS, and it runs like scalded dog! I used a spike's lower with enhanced LPK, and wmd NiB-x BCG. With 62gr it runs stupid smooth and the flash pig works rather like acompensator rather than a flash suppressor. It eats up that 62gr and the muzzle doesn't rise a bit...not even a tad. It's like shooting a 22lr rifle, maybe even less recoil and rise than that! A++++++++++ WILL BUY AGAIN IN A HEARTBEAT!! Was this review helpful to you?

Awesome! November 19, 2014 : Jeff L   I bought this about a month ago. It took only 4 ds to get it. Great fitment to my Aero Precision lower. I did have ejection issue, only because of another company's BCG. This was fixed with thesimple o-ring that goes around the ejector spring. Works perfectly now, and love the look of it.
