Algodoo

Something I made a while ago, to test a type of cartridge. The test cartridges has been replaced with ordinary ones, and the gun has been made into an automatic grenade launcher of bullpup version. Unfortunately, it doesn't include a detachable magazine, but it's still an interesting prototype. Up and down to aim, enter to fire. It fires HE Frag shells, so if you put something in front of it it'll be a blast.
