Specna's ORION™ reinforced gearbox has gained an excellent reputation since it was released installed in the EDGE™ series of AEGs, and now Specna are offering you the opportunity to create your next gearbox build with a solid, reliable shell to tie it all together. Rated to handle heavy springs and including enhancements such as radiused cylinder windows and quick change spring functionality, the ORION™ gearbox shell is probably a tad more affordable than it should be!

Full description


The ORION™ Gearbox Shell V3 is designed for AK AEG replicas but is also the correct shell to use for an AEG AUG, AR36 and SMG-5K/MP5K/PDW gearbox build. This shell includes 8mm bushings, 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 and have your hand-built setup riding the sheer edge of allowed velocity limits at your local site, availing yourself of every tactical advantage in-game.

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.
