Tight Fit With My Lower, Clean Machining & Design May 6, 2021 : Philip from Lakewood Ranch, FL United States   There is absolutely no wobble with my Aero Precision lower and this upper. It is SOLID--unlike with other similarly priced competitors that shipped their own lowers and uppers manufactured by the same facility. Availability is there, which is hard to find these days which led me to check out the MAS Defense options with everyone being out of stock. I'm glad I came across them. This brand is a hidden gem! Downside is that I had no clue when they (I bought two) were showing up at my door due to technical issues with email notifications related to their domain but I'll contact their support team to advise how to rectify that issue.

Can't beat it January 18, 2021 : from GA United States   This is a great combo of parts to make this upper. Can't beat it for the money nowhere. Very well done and as always the Ballistic Advantage barrel is very accurate. MAS Defense customer service is top notch with very fast shipping! Was this review helpful to you?
