Full description


Designed and manufactured to the same standards as the Gearbox Set supplied with the ASG M60E4 and ASG Mk43 LMGs, these complete sets are ready to install into your LMG straight from the box. This isn't a 'flat pack' set where you need to carefully assemble everything, as ASG have helpfully done that part for you! The gears, piston, motor and wiring are all properly fitted and ready for use. All you need to do is remove your LMG's existing gearbox, and pop this fresh one in it's place. While you can use this gearbox as supplied, ASG have designed it in a manner which allows it to be upgraded to suit your needs; whether you want to improve the Rate of Fire (ROF) or modify the FPS, the gearbox accepts standard upgrade components. This factory fresh M60E4 and MK43 AEG gearbox is an invaluable piece of kit for owners of those Airsoft LMGs. Whether you're planning on giving a new lease of life to a broken M60E4 or MK43 AEG, or merely want to have a spare on hand 'just in case', this Complete Gearbox set is a very practical and time-saving purchase.

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
