I have a live round stuck in the chamber/barrel of an 9mm AR build I was building and hoping to complete. I basically wanted to cycle a few rounds manually without pulling the trigger. First round I chambered got jammed in the brand new barrel. So jammed that it broke the extractor on the bcg. It looks like the cartridge is almost fully seated. The company that sold me the barrel did say they would replace it. They did notice some of the barrels in the same batch had extra nitriding and they must've missed one. They said they would replace it. So at least I'm confident it's not the brand of ammo to blame. Any suggestions on safely removing this jammed round so I can have it replaced?
