Description
The CORE™ V2 Gearbox shell from Specna Arms is designed for M4/AR-15 AEG replicas but is also the correct shell to use for an AEG SMG-5/MP-5 gearbox build. This shell includes 8mm bearings, and features radiused corners on the cylinder window, fixing a common weak point in AEG gearboxes which rears its ugly head when using high powered springs. The rear of the gearbox is open for the use of a quick-change spring guide, allowing you to change your spring without having to open the gearbox itself, saving you the heartache of dealing with a potential spring loaded gear grenade if your hand slips!

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.
If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
For more information with fitting parts, or should you require help, feel free to get in touch with our Workshop Department via our Contact Us Page.
