Not sure what blanks you guys were using, but BFA is an obstruction in itself. May be the obstruction was after the gas port and all gasses from your blank were just escaping back through BCG?You got lucky.
I unintentionally fired a blank with a barrel onstruction (too many patches on a jag) and didn't dislodge it.
I was handed a C9 and barrel for a exercise. And told to hurry up. So slapped the BFA on it and got on the bus. Once it was time to fire. It needless never worked, fired a couple before switching barrel.. When I got back, that when I realized was an obstruction. If your theory worked. It be close to the muzzle but was still mid barrel.
I don't think i heard any of the weapon techs using that method to try and dislodge. CGN mod Dwisy had to get a bore snake out of my C7..
With semiauto its a bit more complicated due to the gas port and where the obstruction is. It may not be possible with semiauto to use the "DANGEROUS Dumbest ever suggested" method lol.
