20mm spent brass casings clean and in good shape. Limited quantities available.
20mm ammunition is mainly used in aircraft cannons, anti-aircraft guns, and naval artillery. Make sure to look at the pictures in comparison to the ruler to clarify how large these casings are!










I’ve made a few “swagger sticks” for old Marine brothers using these as grips. The shell casings make attractive grips, and they’re memorable for anyone who was saved by a “Spooky” or “Puff the Magic Dragon” gunship firing 20mm machine guns.
