Here is a shot of one of the many projects that I have going, this is a custom ultra realistic paint marker that I am building. It is meant to mimic the M-10 sub machine gun, sometimes also called the MAC-10. It is CO2 powered, magazine fed, and will utilize empty modified .45 ACP casings and will fire .43 cal RAP4 paint balls.

This is the first preliminary prototype so its all a bit rough, no sense in getting fancy if your just going to change it.

NO you can NOT put live ammunition in it, nor can it be made to function live ammunition. The empty 45 casings are also modified beyond any compatibility with real firearms.
