This is the 2" shell for the Nova N8 rocket launcher. It requires the 1.5" PVC adapter to work properly. This fits two golf balls, or 17 paintballs nicely. Your barrel is lined with a $2 piece of plastic, why not load this with rocks, glass, anti drone netting, eggs, water balloons, stink bombs, or a freshly harvested hornet nest? If it fits, it will fire! use cardboard or newspaper as wadding to hold your payload in the shell.
