Don't really want to spank £17 on a new one from knibbs... Not fussed if it's a bit ratty.

Just stripped this mk2 and it has a solid PTFE type seal... interim plan is to cut an o-ring groove in it, but I still don't think it will be as soft to shoot as a leather one. Right now it's quite harsh, defo not sealing properly. I guess it's a T.R.Robb jobbie...

Thanks in advance,

JB
