Keen Sharp Gear Set - SR25

Keen Sharp
Code: KS-G-SR25
  • SR25 Only
  • Upgrade Gears
  • Reliable Construction

An upgrade over most out of the factory gear sets found in most SR25 Airsoft AEG rifles. Constructed from Alloy and including the Bevel, Spur and Sector gear, this is a sound gearset choice for your SR-25.

Full description


Suitable for those looking for a stronger gear set for their stock spring or if they are looking to get a little more power out of their setup. Often this gearset is a must have for anyone also looking to make a silent AEG DMR build, thanks to the 6 points on the anti reversal latch, you can get as nappier single shot action especially when combined with a nice MOSFET and motor upgrade.


  • 6 anti reversal points on bevel gear
  • Desired for stable builds
  • 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

Package Includes:

  • Bevel gear
  • Spur gear
  • Sector gear

Special Instructions:

We do not recommend that you use these gears in Airsoft weapons where the spring is rated 130m/s or higher.

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.
