"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)

"These gears are great! I have my setup running these 14:1 gears and a Promy M150 with a JG blue motor and have had no problems! The trigger response I get with the gears is insane, the moment i pull the trigger the gun fires. These are the best of the best, they sound great, and mesh better than any other gear-set I've used. When you make a high stress setup these gears are a necessity. Another great feature is the anti reversal latch spots are just the teeth of the gears and lock the latch in so it doesn't come out for no reason. Great gears, will buy again!
