Description
JG AK Complete Gear Box
This is a complete gearbox from JG (Jing Gong) for AK-pattern AEGs. JG is a long-established Chinese manufacturer whose AK replicas have been a popular, affordable choice for many years, and a complete replacement gearbox is often the quickest way to bring a rifle with serious internal damage back into service.
Replacing the whole gearbox avoids the time and specialist knowledge needed to source and fit dozens of individual parts. You remove the old unit, fit the new one, and set up the motor and hop-up, which makes it a practical option for players and site rental fleets alike.
AK gearboxes explained
AK-pattern AEGs normally use a Version 3 type gearbox, which sits in the receiver with the motor in the pistol grip. The exact configuration of this JG unit, such as the spring, gears and whether a motor or wiring are included, is not stated in our listing, so please check the product photos before ordering. If the motor is not included, you can transfer the motor from your existing rifle.
Fitting
Fitting a complete gearbox means stripping the rifle down to the receiver, which on most AKs involves removing the dust cover, stock, grip and front end. Once the new gearbox is in, set the motor height so that the pinion meshes smoothly with the bevel gear, then check feeding, hop-up and velocity. If you are unsure, ask an airsoft technician to fit it.

Compatibility
Designed for JG AK replicas. AK gearboxes from different makers are similar, but wiring position, selector plate and trigger details can vary, so compare it with your existing gearbox and check your model before ordering, or ask us for advice.
Care and maintenance
Use good-quality batteries and correctly set motor height, and avoid long periods of dry-firing. Store the rifle with the battery disconnected, and fire one shot in semi before long-term storage to relieve spring tension. Have the gearbox serviced if it becomes noisy or the trigger response slows.
Who is it for?
This gearbox is for JG AK owners and technicians replacing a damaged gearbox, and for players keeping backup or rental rifles in working order.
Please note: Battery and charger are not included. Always wear eye protection when test-firing.
