I expected to have a few little issues with a new upper. Maybe a mis-feed, or a double, maybe a lack of extraction? Nothing, I was almost let down by this. I took all of my cleaning and files and the like to clean out or make this upper run... Nothing, not one single failure, not one. a little oil at install, and it ran, and ran, and ran. More than 500 rounds the first time out and not one failure. Top it all, it dropped every round where i wanted them to go. less than one inch at 50 yards, and it was tightening up the longer I shot. I think this thing is going to be one of my favorites.
