SHS Steel Double Sector Gear with Specialized Tappet Plate
(Type: Version 2)

"Very good DSG, not as high quality as siegetek (obviously) but gets the job done, with good shimming and aoe, you shouldnt have to worry abut it stripping.

"I put this in a G&G raider combat machine, not impressed. I bumped up the spring rate with an SP120 to get some velocity back from the short stroke but on semi-auto it tended to spit more bb's than shoot. Full-auto was great at @24 rps with the stock motor and 11v.
I tried switching back to the stock sector plate because the one it comes with has a point of release before the piston fires and I figured it was slapping the bb's past the hop-up before it's firing but that just caused mis-firing.
I would not recommend getting this set-up but try finding a faster gear-set to increase ROF so you retain the proper timing and stroke of your gearbox because this just seems way more problematic with the half stroke.
I'm going to try it in a P90 that has problems with the semi-auto part of the trigger assembly and I was going to make it a full auto only anyways.
Decent quality materials and craftsmanship.
