6mm Airsoft Smoke Wagon Shell - Design Mk8

This is a 6mm recreation and modification of the metal shells used in the Smoke Wagon and all Umarex SAA 4.5mm revolvers and the newly released 4.5mm Umarex Cowboy Rifle.

I converted my Cowboy Rifle to 6mm and use these shells in place of metal ones so that I can simply eject and leave them on the airsoft field without worry.

You load each one by pushing a BB into the front till it stops moving. It will stay there without issue.

You can print them at 1mm and 4 walls and get a very smoot
