I bought this set before any reviews were posted, didn't know this set required a half toothed piston, so for the time being I'm still using the stock Marui gears.

yes you must use a half teeth piston.... if you use a m150 or higher take a metal teeth piston.

Syed you goddamn idiot! This gear set is meant to be used with half-teeth pistons, and ONLY half teeth pistons! It simply won't work otherwise, as you displayed...
