5 of 5 High quality. Great service. January 26, 2023

Ordered this upper on a Friday night and it was shipped out promptly the next business day. Fit and finish is excellent. I am digging the nitride BCG along with the BA barrel. Overall, a great shooter for a good value.

Ordered a barreled upper. Upper arrived sooner than expected. Quality is there and definitely worth the price. Only had for a week so have yet to put any down the tube but no complaints this far.

5 of 5 Great value upper April 26, 2021
: Patrick Martinez from AK United States  
I will start by saying that I have not fired any rounds from the upper at this time but if it performs like it’s fit and finish then I will be happy. I live in Alaska and 9/10 times the journey packages take to get to me end up with holes or cuts due to less then average box material used by most companies. The packaging was in near perfect condition and you can tell by the way MAS defense encloses the upper in bubble wrap and brown paper that they don’t want it to move in the box during shipment. I put this upper on a PSA lower I had laying around and there is absolutely no “wiggle” between the different companies parts. All screws were tight from the hand guard to the gas block as they should be, just something I normally check as other companies are a hit and miss.

Overall very impressed and will be a returning customer after a hopeful good testing at the range.

5 of 5 Fantastic October 2, 2020
: from NM United States  
I'm going to review everything I purchased at once considering I had to complete the upper
FORGED CHARGING HANDLE AR-15 - DUAL PULL AMBIDEXTROUS
M16 BOLT CARRIER GROUP 5.56 & 300 BLACKOUT BCG - MELONITE NITRIDE
I purchased all of this to complete the 11.5" upper so doing individual reviews seemed redundant. I mounted the completed upper to a DanielDefense lower then put about 100 rounds through it with no issues. It ran real smooth and is very accurate. I was very impressed with the way the gun handled. I will be doing business again and will recommend to others as well.
