5 of 5 Top tier upper at a bargain price December 14, 2024
: Paul from PA, United States  
Excellent upper, gassed to perfection very soft shooting with 100 percent reliability after hundreds of rounds.  I now own multiple MAS uppers and they’ve all been flawless signifying excellent quality control.  You can customize your uppers and the pricing is very competitive along with excellent customer service.
