@merchantHelios LITERALLY STRAP A GUY TO AN ADJUSTABLE CHAIR AGAINST A WALL, FEED A BRAKE LINE THROUGH THE WALL AGAINST THE BACK OF HIS HEAD AND ON THE OTHER SIDE OF IT A GUY PUTS A 22LR INTO THE BRAKE LINE AND HITS IT WITH A HAMMER

IF YOU WANT THAT FIRING SQUAD EFFECT HAVE MULTIPLE DUDES HITTING OFF MULTIPLE BRAKE LINES IN A ROOM AND DOUBLE BLIND IT WITH ANOTHER TEAM PUTTING THE CHAIR NEXT TO ONE OF THEM ON THE OTHER SIDE OF THE WALL
