Need firing pin spring

[RPK]

I need a firing pin spring for my NHM-90 & can't find one anywhere. Who has them? I've checked Numrich, FAC, etc. Can't find it. Trying to get this thing to quit doubling & sometimes tripling. :huh_small

that may not be your firing pin....I would say its the hammer or sear

Don't know about that. I replaced the fire control group with a Hungarian one once. Still doubled on me.
