So a few days ago I got the idea of modding my jolt to fire 6mm bbs through a straw stuck in a hollow dart. I got to thinking of some mods and I tried one which didn’t work but brought me to another idea. Could I use a pen tube as the barrel in my already modded Jolt? If so how would I seal the hole up around the new barrel? (Don’t worry I have another Jolt just in case.
