The G&G Upgraded Reinforced Piston is a lightweight and very strong polycarb piston. Polycarb pistons are great for keeping a lightweight power train that won't damage the gearbox shell, but at the same time remain strong enough to hold up with mild upgrades. G&G has some of the best R&D in the industry, which is why they gave this piston 4 metal teeth and eliminated the second to last tooth, a known stress relief technique by master technicians. This piston is recommended for use with mildly upgraded guns.
The use of aftermarket airsoft parts is not an exact science. Some parts may require fitting even thought they were designed to fit without modification. Professional installation of upgrade parts is highly recommended.

used on my G&G l85a2, around 22-23bps on a m120, and G&P m160 motor, it was a pretty beast. the piston never showed wear at all, and i loved it, not to mention its three metal teeth really helps.
not too expensive
3 metal teeth

This piston does not work in a VFC SCAR gearbox. After using it for about 5,000 rounds, I opened the gearbox and found that the teeth on the piston were eating a nasty groove into my cylinder. When I compared this piston to the stock VFC piston, this piston's teeth hang down slightly lower.
too big for VFC gearbox.

Piston is tough, but did not like my steel guarder gear, nor did it like my cheap JG gear in my CA reinforced v2 gearbox. Working well with the CA gear. The gear has 1 broken tooth on the bottom of it yet it still works! :P go figure. The teeth of the Guarder gear did not mesh correctly with the piston teeth. The rails needed some major filing and the teeth needed sanded down a heck of a lot (like 1-1.5mm). Will be replacing this with a polycarb guarder piston soon. Will never buy this piston again unless I have a G&G gun.
No 2nd tooth
Teeth did not mesh correctly with reinforced steel gears
Required major filing and sanding to work in a good quality gearbox
