Full description


This Steel Alloy manufactured gear set is designed for Version 2, 3 and 6 TM gearboxes, and is a complete set to uprate your current gearset. The sector gear means that your rate of fire will be doubled, at the cost of losing some output FPS. Usually a higher power spring is installed to compensate for this. The set comes included with a Polymer Tappet Plate which is designed to operate with the Sector Gear to reduce BB jamming, and a Spring Guide Spacer should you not want to install a higher power spring to compensate for the drop in FPS.

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.
