Great upper for the price Thursday, September 24, 2020 : Steven Bittick from Houston, TX United States   This is my 2nd upper from MAS. Both have been perfect finish wise. Everything is tight and torqued to spec. Nothing has been loose or needing adjustment. I have built 2 “budget” rifles, both using MAS uppers. I’m sorry to say, or not sorry depending on how you look at it...but these are just as good as my $1300 DD uppers. The barrels may not have all the fancyness but the machining quality is there and the build quality is there. For a sub $400 upper you can’t go wrong. I have used DD bolts and bolt carriers in both of my budget builds, but that does not in any way (from what I can see) take away from the build quality and what these guys are doing out of SC. You are my number one go to for sub 1k uppers. Keep up the great work. Was this review helpful to you?
