5 of 5 great quality, great price February 19, 2021
: Robert from jacksonville, NC United States  
these uppers are outstanding for the price, a lot of companies over build their uppers to specs you'll never need and you have to pay a heavy premium for their name brand and materials that are not required. instead these are built with materials you'll still never wear out and for hundreds of dollars less than the competition

5 of 5 Looks Wonderful February 12, 2021
: Matt  
Arrived quicker than expected. It was packaged well. Appears to be well made. No scratches or blemishes on the completed upper. Fit right in to place on my completed lower I assembled. Have not had a chance to fire it yet. Everything else though meets my expectations for quality. As long as it fires and is accurate, which I expect it to, I will be a repeat customer for my next build.

5 of 5 Nice looking upper January 28, 2021
: Trevor Teague from Cochise, AZ United States  
Haven't had a chance to shoot it yet, but everything checks out and looks nice. Fast shipping, especially in these faux panicDEMic times. This is not my first MAS Defense purchase and won't be my last either.

5 of 5 Best bang for your buck! June 9, 2019
: Tony from CA United States  
I love this upper. It's well made and high quality and ready to install and go. The original is two toned. FDE handguard and black upper,but I paid an additional 19.99 to make it completely FDE to mach my lower. My lower is an Aero precision M4e1 and it fit perfectly and looks good with it, but the color Is very slightly different but doesnt bother me. In total I paid 289 dollars and I feel I couldnt get a better deal not even from palmetto state armory. The paint is smooth and no imperfections. The handgaurd has qd attachment points and just looks awesome. You wont be disappointed!
