I had my WK out to the range for the first time today and I was getting constant failures to extract. The empty casing would stay in the chamber and I would get a double feed on the next round.
Anyone else having this problem?
My Extractor spring was very distorted, causing the same issue. Their O-ring trick did not help. So I took an AR15 spring, cut off 1.5 coils and she runs like a champ now.
I also added an o-ring to the slot lug which tightened up the upper/lower wiggle.
