  • Average Ratio
  • Upgrade Gears
  • Reliable Construction

If your old gears are tired out or you are looking to replace a brand new gear set for something more reliable and on a budget, then Keen Sharp is for you. 

Full description


This gear set delivers an average rate of fire found in more Airsoft AEGs but they are very durable. The 18:1 gear set can deliver a higher rate of fire when combined with the right motor, properly shimmed and are also durable enough to use with a Dual Sector Gear for some seriously tasty rate of fire. We have used Keen Sharp gears in our workshop repairs and AEG upgrades for over a year now and so far we have received no complaints.


  • Suitable to be combined with a Dual Sector Gear
  • Stamped with white 18:1 numbers
  • Sector gear is a 2 part construction
  • Ensure after some time that the 2 part construction sector gear is secure by checking the 2 retaining bolts are tight, adding some thread lock will preserve the gear's life span
  • Used by staff in store at Patrol Base within the workshop to repair and upgrade many Airsoft AEGs to date
  • When ran in a standard gearbox expect reliable average rate of fire when used and built correctly

Package Includes:

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.
