Solink Motor High Speed CNC Steel Gear Set for Airsoft AEG Rifles
(Model: 13:1)

"Best gears on the market. Yeah, they sit a little high, so what? These gears were stronger than my siegtek gears which BROKE in my BRSS AK build. But these gears? Ran ~500 rounds, opened it up, and no visible wear even with the BRSS system. Goated, just make sure your not using dollar store pieces for the rest of your gearbox.

"I have had two sets of solink gears and both times the bevel gear dimensions have required close to 1.0mm of shims on the bottom of the bevel due to thicker tooth dimensions. In both cases I have checked gear play with no shims between the motor and top half of the gear box and see .05mm - .14mm of play leaving little to no room for a shim.

This in turns pushes the spur gear and sector gear higher to get decent engagement and creates a problem with the sector gears top face interacting with the tappet plate and potentially causes issues with the delay chip rubbing against tappet plate slots. This also leads to problems with most centered piston tooth racks. Perhaps using the laylax offset piston is the move with these gears.

Not bad gears but be warned I have had 2/2 sets of gears sit high (right)
