Blown away
March 23, 2019
: JONATHAN MCCALEB from fort worth, TX United States
The quality of this upper is fantastic and truly speaks to the reputation of Mas. I’ve already taken this barrel out to 400 yards and it has preformed well above my expectations. Shipping was also very quick, I bought two uppers on the same day and Mas beat CBC by by 9 days.

So far so good

: Daniel Wiseman from Bountiful, UT United States
Arrived shortly after shipment even though I live on the other side of the country. Excited to get the rest of my build so I can try it out.

First Time Builder
March 25, 2018
: Steven T
I am in love with my purchase! Everything was super easy to figure out, and Customer Service was able to answer all of my questions. A friend of mine, who has seen my finished AR has caught builder's fever too, and I will make sure that he goes through MAS Defense. Five Stars!

Great build quality
September 20, 2017
: David R
Great build quality! Fits nicely on my lower receiver. After putting about 200 rounds through this upper my only complaint is that the threads didn't get any thread locker. If you don't takethe time to go through and put some on, the floating cage will come loose, and the side mounts will fall off (hopefully not while it's mounted on the quad like mine Oops). Don't let that stop you from buying this well made and affordable receiver though. Just remember to grab some thread sealer before you hit the range! I would buy this product again if I ever need a new one.

Review of Omega 18" & stainless steel barrel
August 27, 2016
: Gary M
This was my first ( wont be last ) dealing with MAS Defence . Was referred to them by my son..SpecOps & he should know...lolItems ordered were excellent ! I made a few calls as I had questions and each person I spoke with were so knowledgeable , helpful and patient with me. I even placed a call but did not leave a message and they called me back as to my inquiry !!! My products are perfect and what I had wanted. You can not go wrong with MAS Defense. I then ordered aYankee Hill complete upper. Oh..I ordered forged handles for both and they came in the upper. Shipping was very fast.Great company to do business and you WILL NOT be disappointed.Gary M.

MAS Defense uppers
February 9, 2016
: Alan S
I got the 18" spiral flutted barrel, added the stainless steel muzzle break. Outstanding accuracy, beautiful upper. Would say I'm suprized, but I've ordered from MAS before. If your looking for top notch parts without the huge price. Do yourself a favor and buy here. I tell everyone I know about MAS. Might be a bad thing lol. Stuff is sold out more often now. Great job MAS.

223 stainless Wilde upper
January 15, 2016
: Gary S
Shipping and tracking info was pretty fast. When I received package it was well packed and really happy with upper. Looks great on dpms lower with monarch 3 scope. Fired 50 rounds through it to sight in scope. Was really happy with accuracy, shooting a cheap light bullet, 1 inch group at 100 yards, could of done better but eye relief was off on scope. Very happy with purchase.
