SHS CNC Machined Lightened Aluminum AEG Piston with Stainless Piston Teeth (Half Teeth)

"My gun jammed and this thing literally went from a circle to an oval. Took out a cloth and some plyers, squished it back into shape and it worked good as new. No damage done to the teeth which was a pleasant surprise. Other than that, super light and fairly solid. would buy again. (just don't jam your gun)

"This is a very nice piston. Out of the package, the piston is very finely machined (no rough edges, no excess aluminum protruding anywhere). My piston head was able to fit flat on the piston without the need for any fabrication on this piston (which is often a problem for other pistons). In addition, this piston is really light. It's about as light as a plastic Swiss cheese piston.

NOTE: You MUST have a gearbox shell that is made out of material that is as durable or more durable than the piston itself. Otherwise, it will begin to wear on the shell and you will begin to see metal shavings in your gearbox. Make sure that your gearbox isn't made out of melted beer cans and is instead made out of REAL aluminum.

"good piston nice and solid.
only I had to buy a different set of piston teeth to match the gear positioning

like it though,
definitly an upgrade from what I had last
