Hi guys i have a question does anyone know the exact length of the valve pin, also or is it just mine when taking my rifle apart and looking at the valve pin noticed it was in 2 separate parts with an o ring in the middle. I would like to know if that's normal and to find what is the standard length of the valve pin. So if anyone owns the noblesse could you tell me the length of your valve pin has a reference thankyou guys please leave your comments below.
