I received my 9mm 10.5" MAS Defense Ridgeline upper and all I can say is WOW!!!! I was lookiing to build a AR style 9mm PCC and had looked at several uppers. I was going to go with another company but after Thanksgiving, almost all of their complete uppers and a good portion of their uppers were sold out. So I went on the hunt and found this complete upper. From what I can tell this is exactly what I was looking for in a complete upper. The rail is what sold me when I saw this company. When I finally got it and assembled it to the lower from my AR rifle it felt and looked great. Still have some work to do though as I will have to get a complete lower now as well as a Colt style magazine magwell adapter. Also have to get another muzzle device as the one I had ordered from KAC was for the other lower and has the incorrect thread pitch on it. Ill know how great it is once I put some rounds through it but as far as looks and what I was looking for, this upper is everything I wanted.

Ordered on Tuesday and received it Friday! Extremely well packaged and lightening quick shipping. Looks and felt well built. Cleaned and mounted sights and assembled it with a 5.56 lower I had using Endomag inserts in Gen2 Pmags. Everything locked up tight as it should. Using the black nitride BCG available from MAS Defense.
It ran flawless with this setup and I am ecstatic with it. Just ran two full mags thru her with no FTF or FTE 60 rounds sent down range and I'm a happy camper. I
Was looking to get the short 4" version but sadly it wasn't in stock so I settled for the 10" upper. With that said folks don't hesitate to buy from these guys awesome experience with them!!! This vet is happy. Side note hit me up when you get the 4" in stock so I can get it also. 😋
