CYMA Newest Type Polycarbonate Piston w/ Full Steel Teeth (Package: Piston Only)

"I am runing this with a cut m160 spring and short-stroked 12:1 shs gear set and get 40rps at 380fps. It shows no signs of wear after 30k rounds. Best piston for the price.

"Pros:
-Compatible with most AEG gearboxes
-Extremely durable rack and body
-Lightweight piston head
-Good compression with most cylinders
-slightly shorter than other pistons, making it almost impossible for it to bottom out at the rear of the gearbox shell.

Cons:
-Heavy internal weight can cause PME in faster builds [easily replaced with a standard M3 nylon locking nut, which lowers the weight considerably]
-Used to cost less than $10... now it's $14

"Very good replacement for a all plastic piston polished teeth

"This is an amazing piston and I run it in my 40rps 320 fps build and after 30k rounds it's still running incredibly well with no wear on the teeth. (due to my perfect aoe) I highly recommend this piston for any build
