5 of 5 Stellar product March 4, 2024
: Jordan Arnold from Urbana, OH United States  
This upper has been hands down one of my favorite uppers I’ve ever had the chance to get behind. It went on my first AR pistol build and I couldn’t be happier. The only thing that would have made this upper any better would have been an adjustable gas block. And evening then that’s not enough to dissatisfy me. The shipping was fast, the product is great, and I can’t wait to build more weapon systems with MAS defense part!

: James from AZ United States  
I am very happy with this purchase. Although the build is not complete yet, the material is lightweight, strong, and all around exceptional.
Looking forward to being a customer for a long time.
