Repeating PaperBall-Guns The student's gun

thingiverse

These two basic toys are designed to launch simple paper projectiles, similar to those used in school with an improvised blowgun. The first one uses a piston inside to shoot the projectile, which is propelled forward by the bolt pushing it, capable of launching rockets or custom cartridges filled with small pieces of paper like birdshot. I discovered that the extra barrel reduces power in this gun. The second one is operated manually using the bolt handle and functions as a simple blowgun. The first gun shoots faster but has less range, while the second is slower and more powerful. Both guns are magazine-fed, utilizing the same gravity magazine tube, they're extremely simple and have loose tolerances, so make your bullets a specific diameter to work better without jamming or shooting multiple balls at once. Have fun!
