Hi friends, I'm having issues locking my nemisis clone. I've fixed the wonky firing pin with a silicone washer now it works beautifully but in 18650 mode with a kick I can't lock the darn thing. When I move the lock ring to lock position it continously fires I know this must be some error on my part, can you help me? Also fire pin will stick on sometimes and I have to unscrwe it. Not sure what I'm doing wrong?? Thanks in advance
