So i started off with a M4 that i got off a trade with my m107. It came with 12 mags and 4 nice batteries. I later bought a new G&P Magpul MUR type body and a DD 12" rail system. The gear box was a 9mm good gearbox. But when i installed it into the gun the wires shorted out in the gearbox. I took the gearbox out and replaced the wiring.....some thing happened. i took a brake from the gun and later bought a new wiring kit again.....well it shorted out again. I then presumed it was the gearbox and bought a G&P complete gearbox and a new magpul ACS stock and enlarged magwell. It all came together and works fine. But i then realized that i should have bought a complete G&P and worked off of that.
