Piston for VSR-10

Tuning, extremely light and durable piston for VSR10 replicas.
The piston is made of aluminum, which makes it very light. The part that works with the trigger assembly is made of stainless steel. This provides us with resistance to wear when working with even the strongest springs.
Two Teflon slip rings are responsible for the ease of reloading and the positioning of the piston in the cylinder.
