Here is my M-79 Grenade Launcher. I built this with my full size replica. The measurements are almost exact. I have been a fan of this weapon since it was used in Terminator 2. That's one of the reasons why I like that movie so much. It had some awesome weapons. The modified 1887 Winchester shotgun, the M-79, the Minigun, and the plasma rifles. All cool. I got a kick out of putting the loops for the shoulder strap underneath. When I get this I'd like to make the sight raise, and I'd like to have it break open like I'm loading it.
