A spring bullet gun with more stable bullets than my last one. You cannot loosen it from the background without screwing it up, so don't try. Just place the bullet in, hit Enter/Return to fire, and then hit \ to clear the shell. It's probably best to clone the bullet and move it while cloning to put the bullet into the gun (if you undertand what I mean).

The gun can't shoot too fast, but if you check the bullet's speed, you'll see that it flies at a speed faster than mach 1.

If you change the bullet density back to default, then the bullet will go faster than 700m/s! So, have fun with it, and if you happen to improve it somehow, post it as a response !
