This is every part needed to build your own M79 40mm grenade launcher. It's comes with a receiver casting and blueprints. All components for receiver, both a wood and fiberglass stock, complete sight assembly, and a repaired barrel. The barrel was demilled with a hole at some point but professionally repaired. Beautiful parts will make a gorgeous DD at some point. Asking $4,400. As some of you may know, tracking down all the components is nearly an impossible task these days and has gotten to be incredibly expensive. It is all here.
