Just realized one if my 2 GK1 spare parts bags has a few K1 orings in it. Couple small ones and a valve o ring.. go figure the o-ring ive been waiting for. Wolfiek said they were out of stock and i said i believe they both use the same 11.6x1.8 o ring. She replied with “i dont think so” ..
One in my bag and other from a K1 spare parts kit i grabbed.

Interesting, I don't have such an o-ring in the bags I've seen.

GK1 manual shows brass screw oring (#59) as 4.5x1mm (https://www.hubenairguns.shop/colle...en-spare-parts-for-gk1?variant=47416272224588).

I bought some from oringsandmore.com and they're WAY too big. I end up using a 2.5x1.5mm with sanded down OD to fit. Gun holds air now but the brass doesn't go in all the way because the oring is still a little big. Anyone else run into this?
