Have you cleaned out your bolt? Also, what ammo are you using? Is it one brand or several brands the light strikes happen?
Ive chected the springs and they are all correct
They both have the enhanced spikes trigger in them. The spring was in right. I never hada a problem with the trident 450 upper on the spikes lower. Didn't start getting the light primer strikes until I put the JM barrel and bolt on to the spikes upper on the spikes lower.
Gunsmith said it was the gas block. I guess one of the set screws was loose? Going to go shoot it to see if its running right now.
It's maybe possible if the gas tube got so out of alignment it kept the carrier from fully going forward (bolt not fully cam'ed). seems unlikely though. good luck
