Siegetek Concepts Precision Airsoft AEG Gear Set (Type: V2/3 / 26.67:1)

"I have the 14.09:1 gears, sp140, and an ASG 28 TPA motor--instant response but plan to get 10:1 for even more response.

Pros: indestructible if shimmed right, many options of ratio on the market.

Cons: price

"I've had these gears in my JG SL-8 for almost a year now and they ARE the best gears I could get. By far. They do take some trial and error to get them shimmed right and running at optimum speed. I changed out the bushing to Modify 8mm ceramic bearings and have this coupled with a gt-45000 motor from 6mm shop. I get about 38 to 41 RPS depending on the charged of my 11.1 lipo.

I could not ask for a better setup. Warning though..If you use these, make sure you change the piston to a full steel tooth piston and dont skimp on other internal parts.

My sl-8 is now a full SAW and it is terrifying. I HIGHLY recommend any gear from seigetek. I'm pulling an m120 spring with a bore up kit and I get about 328 FPS with 0.25 BBs. Only issue I have had, is I put in a Gate Titan mosfet into a CNCed gearbox. The issue I had is the selector plate kept breaking on me. These are NOT for the faint of heart, but if you want a solid build that can scream, then these are for you.

"these arrived in great condition and these gears are the best in the world in my opinion (at least for now since its 2017). these gears can handle a prommy sp200 in my DMR. Ive shot about 5000 rounds and I reopened the gearbox to check everything out. THE GEARS HAD NO SCRATCHES OR DINGS OR ANY FORM OF DAMAGE AND IT ALSO DIDNT DAMAGE THE TEETH ON MY THOR2 PISTON BY ANGEL CUSTOMS. if you have the money for this investment then do it!! you will not ever be let down in any build youre doing with siegetek gears. BUY THEM IF YOU CAN, YOU ONLY NEED ONE SET THAT WILL ALMOST NEVER NEED TO BE REPLACED. (im still trying to see how long they last so i will update this review on a later date)
