Scorch, what kind of pressure is coming out when the gasses exit the barrel? I've often thought a few washers in a tube welded in place, with holes drilled in each washer (one hole each at the 1, 2, 3 oclock and so on) would be fairly effective. I just don't know what kind of pressure is coming out and was curious if that would just turn into a pipe bomb of sorts.
I know it wouldn't be legal, but it was just a thought
