Build the ROKR Thompson submachine gun from 275 wooden parts into a working rubber band shooter. A detachable drum magazine loads ten wooden shells that fire in sequence at roughly five rounds per second. The finished model holds, racks, and shoots like the silhouette it’s modeled on.
 
The build
Load ten rubber bands into the drum, snap it into the receiver, and the ROKR Thompson submachine gun fires them in continuous succession at about five rounds per second across an eight-meter range. A wound internal mechanism releases each band as the trigger cycles. The drum detaches for reloading, the same way the original magazine did. Assembly runs around 275 pieces with small springs and thin parts that need careful seating before the action cycles cleanly.
