5 of 5 Very nicely put together January 7, 2024
: from Minnetonka, MN United States  
MAS defense built me this with a BA 20 inch fluted barrel 3 years or so ago. I also bought their BCG. Quality is excellent. I put a nice trigger and put it on a cheap K&G receiver. Fit was surprisingly good with no wobble. I have been using their build to shoot 600 yards regularly. Their free float rail is very well machined, no sharp corners and excellent finish. I really like that they made it big enough for the suppressor. That is what made them stand out (at least at that time) amongst other manufacturers.
It is obvious that for my build they used good quality parts. And having BCG in different finishes is a big plus. I would suggest adding DLC (diamond like carbon) for BCG finish too if they can acquire technology. Very easy to clean.
This company build quality uppers.
