Description

Prop 20mm aircraft ammunition with printed ‘brass’ shell and projectile. Very closely matches old Air Force M56 20mm ammunition. This is a two-part model with a shell and projectile. 

Projectile models include 3 or 4 color changes depending on the projectile you are modeling. I also included a projectile model that fits empty 20mm brass – nice if you are making a commemorative display.
