SledgeThunder Barrel v2

This barrel was designed around the rival rounds 3 shotshells but can be used with some of the other shell types including the double shot using elite darts but may not function with the double shot with anything other than stock elites and does not work with the triple shot the shets for that barrel follow this link https://www.thingiverse.com/thing:4102507



V2 is finally out I added a gasket o-ring for better seal and made the barrel diameter the same diameter as the inside of the shell
