I have basically 3-4 boxes thru each rifle and the all operate flawless. Maybe had a few fte issues, within the first few shots but after that the all run great . Have u tried to message the feed lips on the magazines at all ??I got my Monster barrel dialed in after toying with the gas. Around the time the failures got bad was right when I started using my suppressor....when it was 90+ degrees. Turned out my rifle was way overgassed and was having timing issues. Loading with different powders and fully opening my gas block to max bleed got everything running smooth. I use ASC 10 round Grendel magazines and ASC 15 round ARC magazines trouble free.
I just got a new barrel in about 2 weeks ago and will be giving my 20" Monster to my wife. Nothing wrong with it, just wanted a longer tube.
