4 of 5 Great February 18, 2021
: from Killen, AL United States  
Good upper only thing is it didn't come with a charging handle or bolt carrier group. Needs to be more bold, didn't see it until my order was already in transit

4 of 5 upper reciever February 15, 2021
: Robert Schreffler from Mulvane, KS United States  
although I am satisfied with the product as a whole, the finish on the upper reciever is flawed. the only reason not to recieve 5 stars.

5 of 5 9mm upper May 7, 2020
: Ryan Peters from TURBOTVILLE, PA United States  
Looks like a great fit and finish. Love the ridgeline handguard! Mated up good to my 80% lower. Shipping was really fast even during this "pandemic" Will update after firing test. Thank you MAS!!

5 of 5 Fantastic product, great price. April 30, 2020
: Luke from FL United States  
I'm not easily impressed and I value my time and money. I had searched for months looking for the perfect 9mm upper to for my newest AR pistol. I had considered building it piece at a time, but could rarely find the parts I wanted in stock and for a good price. After searching for quite some time I came across MAS Defense 9mm uppers and browsed their pistol uppers looking at all the options they offered. I settled on the 8" Ridgeline upper and TiN finished bolt to complement the great looking upper.  Great buying experience and fast shipping in these uncertain times (Corona crazyness) solidified the feeling I had made the right choice.  Arrived promptly, and well packaged. Pinned it to my Sharps Brothers lower and loaded up mags for a trip to the range the next day.  Needless to say she ran flawlessly straight out he box. Good looking pistol with all the perks I wanted for a great price.  Very happy with my purchase and look forward to many more trips to the range.

This upper feels great ergonomically and I had no issues assembling with the rest of my gun.
