I have for sale a G&G MP5 with a complete gearbox rebuild. All the internals aside from the hopup assembly have been replaced. Gearbox is a Lonex complete drop in MP5 Gearbox Assembly, minus the following parts: G&P Cylinder Head VFC 3/4 Ported Cylinder SHS 13:1 gearset VFC Spring Guide Franken-motor, built off of a ASG 18k GATE NanoAAB Includes 9 midcap magazines, 5 are G&P Metals, and 4 are MAG plastics. -It is missing the bolt handle and mock bolt, I bought it used and never replaced them. Causes no detriment to function.
