50% scale working model of the Modelo Polytactico. I used assorted M2/M3 bolts, nuts, and pen springs to match a scaled down version of the full size shotgun. I didn't document the hardware used, but larger bolts I used M3, smaller bolts I used M2, and very small parts I cut the head off a M2 bolt to act as a pin. Ream out where needed with a small drill bit to make fitting easier. The stock pieces are now a single piece to make assembly easier.
