I have Wilson Combat muzzle brakes on 2 of my AR's. I noticed way back when I first got them that the external dimentions looked almost identical to a pre ban flash suppressor. Finally dug out my blank firing adapter and tried it. Wouldnt quite fit. After a little work with the dremel, it fits like a glove. Loaded up a few blanks and went out to the barn. Flawless. Now I can pratice a few things that dont require live fire but still have little realism to it.
Anyone know a good place to buy more blanks from? I have a few but need lots more now.
