SBR build November 20, 2020 : SR Watson from Bauxite, AR United States   Upper is very well constructed. Exactly what I wanted. No parts that I would remove and put in the "junk" box. Finish is outstanding. Was this review helpful to you?

10.5 Barreled Upper October 29, 2020 : Andrew from Illinois   Shipped extremely fast, probably 3-4 days to my address! Fitment was perfect on a DSArms lower. I put on a Cloud Defensive CORv2 on, so I had to take off the milspec barrel nut. Man they really had it on there, a good thing! Haven't fired it yet, but I'll come back when it's been tested. Great experience otherwise Was this review helpful to you?

Almost perfact October 29, 2020 : DAMIEN HARRISON from BAKERSFIELD, CA United States   Even thought u were supposed to send a mil-spec barrel nut for my free float quad rail but sent me a regular barrel nut now I have to purchase one with threads on it AKA mil-spec barrel nut still very happy with the speed of the order and the product itself will order again feel free to send a barrel nut to say it's all good if you don't it's still all good but not as good thank you Was this review helpful to you?

Good price for a complete upper. October 5, 2020 : Joel Fernandez from Charlotte, NC United States   The upper comes well put together. Barrel nut extremely tight and the gas block screws locked in with a type of locktite. All in all good quality for the price. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- MAS Defense Reply: Joel, The barrel nut is installed using lithium grease and is torqued to 40 FT LBS. We use a blue removeable loc-tite on the gas block set screws and torque them to 40 INCH LBS to prevent them from coming loose. Thank you for your business and your feedback!

Egg Shaped Crush Washer April 20, 2020 : BRAD M.   Ordered the 10.5 complete upper for a pistol build. Only issue that I have was I needed to remove the gas block and tube. I removed the birdcage and tried taking off the crush washer and it was egg shaped and couldn't get it to slide off over the top of threads on barrel. I had to cut the crush washer off to remove the gas block and tube before I could add the components needed to finish my build. Was this review helpful to you?

10.5" 5.56 / .223 BARRELED UPPER - MIL SPEC BARREL December 19, 2019 : JD from goodyear, AZ United States   Nice tight fit on an Aero Precision lower. Too tight on a RRA pistol lower (but it was for the Aero anyway). Was this review helpful to you?

Fast shipping, Quality Product! September 21, 2019 : Cobi Aloia from Pell City, AL United States   I ordered this because I was wanting a new upper, but couldn’t find any with a quad rail. I ordered a quad rail to go with this upper, and masdefense put it on for me, as well as the flash can in my order. On top of saving me time and money, I got my package in 2 days. These guys are like the amazon prime of gun accessories. The upper has made defense logos on it which look super good on my new rifle. Everything is A+ quality. Excellent customer service, excellent prices, and excellent shipping speed! Was this review helpful to you?

2nd Upper from MAS April 18, 2019 : Brandon from OH United States   Great price and again another MOA barrel from MAS. Added a Spikes upper to match a Spikes lower I had. It shipped 2 says after I ordered and I received 2 days later. Great job all around. Was this review helpful to you?

Quality for a Great Price! April 9, 2019 : Mark Seitz from Henderson, NV United States   Hands down this is one of the best complete uppers for the money. The finish is great on the barrel and the upper. I had to call customer service with a couple of questions and they were great on the phone. They even mounted a Troy rail that I bought separately before they shipped it. Was this review helpful to you?
