Genuine Viton o-rings for maximum durability and consistent FPS. Replace and lube your o-ring with Viton o-rings to get back the power!

Yep so far so good. More solid than many O-rings that have too much twist in them. They have a porous feel to them unlike shiny O-rings.
Has a bit more density than rubber, so I guess more tougher and better wear resistance.
