It could, but it's doubtful. Being a direct gas system, it still requires the return of gas to work the bolt. Granted, the small amount of recoil could cause a stove pipe, but it's a small chance. I think if anything, the bolt would hang about 1/2" or so open. It would probably be enough to see a small amount of the brass. From what it sounds like, there's a fair amount of gas blowoff by the gas block.
