This is a printable 40mm PD projectile that uses a shotgun primer and fixed firing pin to ignite a combustible payload on impact.
This design incorporates a bore riding safety that is ejected after the projectile exits the muzzle of the launcher.
Additional components required are a 4D nail, a 209 primer, and a spring from a ballpoint click pen.
