5 of 5 Great Product January 7, 2021
: Robert Jaster from Selma, TX United States  
Bought this upper for my second AR build and it is perfect. It is very light weight compared to my other CBC upper. Fits tight to my lower with very minimal to no play, and shipped well packaged with no defects.
I have not had a chance to shoot it as my build is not complete yet, but it seems like it will do exactly what I need it to do. I will follow up with a range report once I am able to determine accuracy as there is not much online about how accurate these uppers are.
I will be buying my next upper from Mas Defense due to their quality and how light weight they are.
