I have one I will be taking out of my nxt marker tomorrow night. As just got a stainless one. Will do pic's when out. Think they are the same. Won't have o rings as dont have spares atm.
Here ya go buddy. I found some orings so left the ones in it. Will send you both. The one with anno wear on edge. Don't know what condition threads are in. Other one is from nxt and is ok. Call it £6 posted. And will post tomorrow for you.
