5 of 5 Quality as always September 6, 2025
: ACfromNC from Waynesvegas, NC United States  
Not my 1st upper from MAS so I knew what to expect. Quality steel and aluminum parts as well as cerakote I used the buffer weight and spring from my LR308, used a carbine buffer tube like my LR308 and it is extremely smooth. I was not sure what to expect with the rifle gas length and carbine buffer, tube and spring but it is much smoother than my original LR308 which is really nice. I Shockingly, this did fit my DPMS GEN 1 LR308 Lower it was about a mm or 2mm off from fitting completely snug. Fortunately I had another lower laying around that I chiseled out and it fit perfectly. The lower that fit perfectly was a lower that was supposed to be a replica of an 80 DPMS GEN 1. A lower that required a longer pivot and takedown pin modeled after the older, larger DPMS lower. Always happy when I buy from MAS. shipping is incredibly fast, the quality is always there and as long as they have the caliber I need, my build will be built with their uppers and parts.
