Having an on going issue with my ar15 where super safe mode will work for 4,5,6 shots sometimes and then the bcg will get stuck almost all the way back. No round in the chamber or jam, it just stops cycling and gets stuck, I either have to mortar it or tap the takedown pin out until it racks back forward. I’ve cleared the auto sear shelf out with a dremel and taken a fair amount of the SS lever and nothing really helps it to work better. Gun works flawlessly in single shot. Any help would be appreciated before I grind this lever all the way down 🤣
