Introduction: The G1 Lego Under-Barrel Grenade Launcher
MY WEBSITE: http://sites.google.com/site/bblegobrickworks/Home
For the G2, I intend to add many different new features, such as: the firing system will be semi-automatic, and will be able to hold up to 2-3 shots' worth of rubberbands, it will be shorter, and there will be a true trigger placed on it.
