The Element 300% Torque Flat Gear Set w/ Polycarb Piston is an economical upgrade for your AEG. If you're looking for a cheap and easy fix for a higher FPS then the Element Gear set is a great solution. However, for those with a higher standard for quality, the Systema or Prometheus gear sets are highly recommended by Airsoft GI.

comes with everything shown, it doesn't say in the description, but when i got the gears they were rated to an M155. I'm using mine with an m140 and a high torque motor, they didn't pull the m140 back with an 8.4 V battery so use a 9.6 or higher. they are a bit nosier, and does slow ROF quite significantly, i might get 4-5 rounds a second but i think its worth it to pull a powerful spring.
the gears them self looked high quality, but the gear that connects with the piston had a defect on the shaft going through it, which i needed to ground down, it did make shimming difficult- just warning any buyers they may have to do the same.
-plenty of extra shims
-had to grind that defect off which made shimming difficult
-i agree with the other post that the piston doesn't look the best but once again that's not why i bought the package.

Gears look nice and were very easy to shim, a little noisy but that's because they are a straight cut gear. I didnt use the piston it came with because I got a piston and cylinder head kit along with this but the piston it came with is poly-carbon and I preferred the all metal kit I bought.
Strong looking gears
Came with plenty of extra shims
Noisy (straight cut gears so I expected it)
Cheap looking piston ( I didn't get the gear set for the piston anyways)
