Shot this upper the same day i got it and it runs flawlessly. Also looks great. No regrets using this upper for my first AR pistol build

Let me start off by saying that this upper looks awesome. The MAS Defense logos on it really finish it off. I had everyone wanting to check it out at the range. I have it paired with a PSA pistol lower, the MAS Defense bolt & buffer and a Primary Arms red dot. My first trip to the range was a real disappointment. I used some Means Endomags. I had either double feeds or light primer strikes about 50% of the time. I have heard that Endomags can work great with some builds & not with others. Maybe the bolt? I decided to get a KAK Mag Well Insert and some Metalform Colt magazines and VIOLLA!!! I put 100 rounds down range without a hiccup. My indoor range is only 45 feet but the groups were super tight using Norma & Blazer Brass. I will definitely be purchasing from MAS Defense again!!
