The Element High Speed Gear Set with Piston is an economical upgrade for your AEG. If you're looking for a cheap and easy fix for a better ROF 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.

Got these as a test. Ive always wanted to build a high speed setup and never really had a reason to have one myself. Since Airsoftgi had a sale for these gears I said why not so I put together my Stubby m4 with a crane stock and sd front end and matched these gears up with a 7mm bearing gearbox,m110 spring,bearing spring guide,bearing piston head and a GP 120 motor. I do all my own work and tech work for my team and others in my area. After shimming the gears for an hour (I wanted everything perfect) it was ready to rock and roll. put it a 11.1v lipo 15c 1100mah buffer tube battery and tried the fps got around 367 and 25.1 RPS not too bad. I did put in my Tenergy 11.1v 20c stick lipo and tried again the RPS jumped to 33.2 rps ill never need that much but its nice to know these gears can handle that.
cost of the gears either on sale or not isnt all that expensive and you get shims and a piston
cheap enough if they break get better ones
easy to install
fits perfectly in a CA mechbox
piston needed alittle hand finishing (sanding and cutting off excess plastic from when they molded it
shims suck i threw mine away (used modify brand shims)
needs a sector chip

So far I installled them very easily. The gears went right in the 8mm ball bearings with no modification. They are very soild and work great. However the piston is standard quality, its good for a back up. But if your just looking for a gear set for 8mm bearings, its a good buy.
Good easy to istall gears for 8mm bearings.
Great quality metal, very soild.
Comes with piston.
Piston is standard quality.

Ive had these gears for probably a year or two now and they are still in perfect condition. I am pulling an m90 or m100 (depends on what field im going to) and firing at 26rps. The shafts were a bit big though when i installed bearings but it just took a few minutes of filing. However, unlike the gears, the piston is just okay. Its nothing special, comparing it to a stock CA piston, the stock CA piston is a bit better quality wise. Im giving then 4 1/2 stars but im in a good mood so ill go with 5...
...however, results may vary as ive heard element's quality control is bad so maybe i just got lucky with a good gearset
-gears are amazing, holding up very very well... probably fired 30k rounds through them with little to no wear
...great gears,what more can i say
-piston is of lower quality
-gear shafts are a bit larger than standard but in a way i guess this is better as you can always file it down... on the other if you order gears with too small of a shaft, there's nothing you can do about that.
