The Lego Grenade/Rocket Projectile Launcher (The F1)

I was looking online and I saw that there were very few grenade launchers made out of lego, so I decided to make one. Some pros of this grenade launcher are: -very strong -can shoot many different projectiles, of different sizes -accurate(for a grenade launcher) -range of 25+ feet (depending on what RBs you use) -the rocket has lots of stopping power -looks cool Cons -long reload time (about a minute) -no magazine (single fire) -the top moving panel is annoying -fairly heavy I will try to make a lego frag grenade for the launcher. Sorry about the crappy camera angles near the end of the video.
