THIS MODEL IS BASED ON BREWBOY UMP45. WITH SOME MODIFICATIONS.

I ADDED 3 CHAMBERS INSIDE THE GUN SO YOU CAN PAUSE THE PRINTER AND FILL WITH FISHING LEAD HAMMERED DOWN TO THE SIZE.

I USED REGULAR 9MM SHELLS AND ADDED THE PLASTIC BULLET PROFILE, YOU WILL HAVE TO DRILL THE SHELLS FROM INSIDE OUT.

ADDED A HINGE TO FOLD THE STOCK, ALSO THE HINGE PIN IT IASELY REMOVED IF YOU WANT TO USE THE END (NO STOCK).

SUGGEST TO DRILL THE HINGES TO CLEAR ANY PLASTIC FROM INSIDE,

-------------------------------------------------DONOT INSERT THE HINGE PIN UNLESS IT IS VERY CLEAR INSIDE, THE PIN HAS TO GO IN AND OUT WITH NO EFFORT.--DONT FORCE IT--------------------------------------------

THE SPRINGS YOU CAN FIND ON BREWBOY MODEL WITH THE ECXEPT ONE SPRING I ADDED FOR THE STOCK LOCK.

IT IS 5MM DIAMETER X 14 OR 15MM LONG

-------------------------I PAINTED AND MADE IT LOOK IT WAS IN A REAL BATTLE ALSO WITH ALL THE LEAD INSIDE IT LOOKS EVEN MORE REAL
