A spare piston V2 for the SSR15.

This piston combines its reinforced polymer body with a set 7 of steel teeth. A unique solution which combines two important traits for such a piston.

The polymer body keeps it lightweight, allowing for fast travel in the cylinder and resulting in a great fire rate. On top of that, the reinforced teeth give the piston extreme durability when it’s in touch with the Piston gear. A win-win solution!
