SHS High Strength Polycarbonate Piston for Airsoft AEG Gearboxes
(Type: Standard / 7 Teeth)

"I got the 14 tooth lightened as a replacement for my Krytac Trident mk2. The original piston has plastic teeth ended up getting stripped. This piston worked as a perfect replacement with the added durability of all metal teeth. I've put thousands of rounds through it now and it shows no signs of wear when I open the gearbox. It's a cheap upgrade that is definitely worth it.

"I bought the 14 tooth lightened piston. It was to replace the old g&g piston that I had. The old piston was only polymer and had started wearing where the gears were engaging. This piston is actually lighter and more durable than the old piston. Would be an amazing piston even if it was $20. Even better piston for $12. If you are looking for a durable but lightweight piston, look no further.

"I love SHS pistons: they meet all the important criteria of a piston at a great price. My go-to for all my builds. One thing to note is that the 'High Speed Lightened w/ 14 teeth' (one with square holes as opposed to round holes) is about 1.5mm narrower than the one with round holes. That can be a problem depending on your gearbox shell. I put them in a Lonex gearbox and the piston was popping right off the guide rails. Could be the gearbox shell itself, so check your gearbox to make sure it's not one with a wider space for the piston before buying that model of SHS piston.
