A lot of people ask if you can convert the blank guns to fire the live ammunition?
Blank guns are made from inferior metals and cannot handle the pressures from live ammo. The barrel is usually designed to be permanently blocked and not designed for projectiles.
Front Firing blank guns vent flame and smoke from the end of the barrel that is not plugged. The front fire vents the gasses through an opening in the barrel and and has a red or orange tip that is screwed into the muzzle (required by law) and sticks out further.
Top Firing blank guns are also called side venting blank guns. The top firing blank guns have a plugged barrel and a small red or orange plastic insert screwed into the end of the barrel (required by law) as an added safety precaution. (The red tip is only visible from the front view). The top venting blank guns vent the flame and smoke from a vent hole in the barrel (usually underneath) instead of from the end of the barrel.
