"Great gears. The piston is pretty average however, so I use the Modify titanium coated one instead. I get around 38rps with my set up off of these. Very satisfied!

-Very durable; they will last a long time
-Auto shimming (could also be a con if you're picky)

-Compatibility issues

*I had to buy the AIM anti-reversal latch because none of mine worked smoothly at all. It's a minor cost, though.
*Auto shimming limits your FPS, as you should not go above an M100 because the springs allow the gears to "float up and down" too much, which will cause them to strip much faster. This can also mess up your AOE with the piston, which leads to a stripped piston very quickly.
*M90-M95 spring suggested
*Filing on certain gearboxes may be required. If you don't know how to shim or correct an AOE, you should not be installing this yourself. Do research on these things as this is not a "drop in" upgrade. It requires much tuning and patience.

"These gears are superb! Don't be worried when it says they carry no warranty, they work just fine and will not break your gun. My G&G cm16 raider was broken for a while, and after taking it apart I saw that the stock spur gear was stripped badly. I bought this gear set because after a year of use, my gun chronos in at ~260fps, so I decided I wanted to have an advantage in RPM. I have no use for the piston yet, however it seems to be sturdy and has metal teeth so it will make for a good replacement. If you plan on purchasing these or any internal upgrades, be prepared to take your gun apart numerous times as it will need adjustment before the gears work perfectly, and I must say that taking a gun apart is a rather tedious process. All in all, these gears have saved my broken gun and made it better than it was before. 5 out of 5 stars, thanks a lot Evike!

"I got this gear set as a replacement for the gear set in the KWA KM4-A1 2GX. Unfortunately, my original gear set wore down on the sector gear and piston, and since I was running an 11.1 Lipo at around 22-25 rounds per second, it was predictable that I would need to replace the gear set soon!

In comes this gear set! For the price, it is definitely a good investment, especially if you are aiming for that high rate of fire, but make sure you do use a low power spring (M120-M130 or equivalent max), because you could wear your gears down faster if you use a stronger spring.

This gear set was definitely worth it, the only reason I give it four stars though is because the floating gear set up did not work properly. I followed the steps to use the springs to help the gears float "perfectly" inside the gear box for maximum performance, but all they did was cause my box to lock up. Took them out and the box ran at 150% efficiency again!

Good deal
Piston AND Speed Gear Set
Full metal teeth on piston

Floating Spring system didn't work (for me).

Overall, definitely worth it!

  • Review:
    This piston is among the best piston in the feature it offer and the flawless construction it is equipped with. As advertised, the CNC steel rack of teeth with a fully carved piston body provides the best of both worlds. The design allows this piston to out-perform in both high speed and high power applications. Simple examination will see that this piston is also equipped with a widened strip of teeth for better gripping and chance of stripping. The steel teeth is removable in the event of wear and tear which is also a plus. Spare teeth strip can be located here on!
