5 of 5 Amazing! May 30, 2023
: Jacob Stradley  
At first I was kind of skeptical because I haven’t heard of this brand (like some others on these reviews) but I was called to confirm my billing and shipping address and the guy was super cool and nice! When the product came in it was pretty nice quality and everything so far seems to be really good! I’m super happy with my order and 110% recommend MAS Defense!

5 of 5 Excellent Service July 23, 2022
: Trenton Blevins from Reeds Spring, MO United States  
The team was on top of it. They called me once the build was finished and gave me a shipping estimate that was very fast, 3-4 days after purchase. The quality of the build was better then expected and up to par with Aero, or BCM, if not better in my opinion. The laser engraving was spot on. I was a first time buyer and plan on returning 👍

5 of 5 Great upper very impressive May 7, 2021
: CM from Fort Collins, CO United States  
Great upper well built quality hand guard and love the light weight faxon barrel. I was a bit worried at first since I had never heard of this company but they did not disappoint and the shipping was super fast.  MAS defense definitely will have my business from now on.

5 of 5 WHOA!!! March 11, 2021
: James from PA United States  
This is a super sweet set up especially for the money.  I did have to go to another retailer to get a BCG so that was the downer part.  I mean I knew I would have to but it would be cool if MAS would include in the upper kit.  Light, fit and finish is excellent!!!
