3D model description

Adapter to use AP cam870 or tanaka shotgun shells.

This allows the use of the cheaper shotgun shells in the grenade launcher.

The APS CO2 shells can be bought as little as $5 each if bought as part of the big bundle and deliver more power than most moscart shells. They are also lighter so carrying 20+ rounds isn't as heavy.

I got this in preparation for making a functional mk19 grenade launcher.

Please note before printing test that your grenade launcher firing pin is small enough to fit the shell! shotgun shells have a smaller firing pin than moscart grenades.

3D printing settings

Print vertically small supports required for the lip.

settings depend on layer height and line width but for standard settings recommend 3+ walls and at least 20% infill
