Alright, I came up with a few ideas at once, so here they are.
1: The Recoiler
It's a rifle. When you fire it, it fires 2 projectiles. One flies forward very fast and does 100 damage, while the second projectile flies backward and hits you. It does no damage, but it launches you up at a 10 degree angle. Not sure what this would be useful for.
2: The Self Delete Gun
When you use it in normal mode, it's basically a T+T2 Classic Pistol. When you right click, the model changes so it appears to be pointing at the shooter's head. If they fire while in this mode, they kill themselves. Could be useful for a "police standoff" Blockland movie.
