Nerf Sledgefire Barrel: Trilogyfire!

as my 100th design, i am releasing the Trilogyfire barrel. remixed from the Sledgethunder barrel, this allows you to fire triloy shells out of your sledgefire. not sure how it'll fare, and only an experienced modder should attempt this. it likely wont be easy to make it seal to your sledgefire plunger tube for max performance.
