: James Levy from Fort Mill, SC United States  
I loved the look online and was blown away when it arrived within a week!   Customer service was exceptional! Ease of ordering was unbelievable.  Quality is out of this world.  This is my 2nd upper and will not be the last.  This is the only shop I will ever purchase an upper or parts from.  Thank you MAS Defense!   Merry Christmas!!  Now that’s an UPPA!!!

5 of 5 Great Upper January 17, 2022
: Adam O from Western Colorado  
This is another upper I have purchased from MAS (repeat customer for a reason!) and it is excellent.  The fit and finish is great on this piece.  It has a very standard matte black finish, and matches well to all hardware from other manufacturers.  No blemishes or evidence of cheap manufacturing.

Order fulfillment was smooth and shipping was quick.  MAS is great to do business with and this is another fine product from them.  I haven't shot it yet but if it performs like our others, it will be MOA to sub-MOA without even trying.
