Algodoo

I FINALLY DID IT!!! some of the mechanisms (I mean a LOT of them) were inspired by J-dewd's MG. I just thought I might make a blow-back version of the concept and make it into a grenade launcher. The grenades DO explode on impact (as they should). This weapon fires from an open bolt and is fully automatic. The weapon can be transported (it is not fixated to anything). The trigger can be pushed forward or you can push enter/return. Up and Down arrows aim.

This weapon is still a work-in-progress, so expect updates in the future.

*Edits:

-December 30, 2013: removed extractor (it was unnecessary), improved feed mechanism, reduced the exaggerated recoil by improving recoil buffer, improved firing mechanism, and made other small changes as well.
