This 69.8mm piston is built for gearboxes that normally destroy stock parts. By using DuPont Super Nylon, Angel Custom made a body that absorbs shock rather than shattering. It’s a durable, lightweight foundation for high-performance setups where you need the piston to survive thousands of rounds without failing.
This piston uses a 13.5 hardened steel rack to handle the constant hammering of a high-speed gearbox. The Gold TiN treatment keeps things slick and lets you spot any red-flag wear during routine maintenance. It comes with ready-to-go AOE, making it a true drop-in upgrade for most gearboxes. It’s a reliable pick if you're putting together a high-end build and don't want to worry about your piston stripping.
The KRATOS II is rated to handle up to 55 RPS at 1.5J, so you don't have to worry about PME in high-speed setups. It drops into most AEG gearboxes easily, but a common trick for high-stress builds is gluing the steel rack into the body to make sure it doesn't budge. If you're building a custom gun that’s going to take a lot of abuse, this is the piston you want.
