Ar9 100% reliable, maybe 500 rounds, then tip of firing pin broke. Got a CMMG replacement, now getting lite strikes maybe every third round. FP spring looks good, flushed FP channel with gun scrubber. Still no joy. FP seems to protrude far enough. This is with Winchester 115 white box which use to run fine and no problems in my scorpion Evo. Gonna try different ammo and new FP Spring. Any other suggestions?

Is this a CMMG build?

I'd try a firing pin from the BCG maker. Maybe a tolerance or spec issue.

Yeah, emailed Spinta. We'll see what they say.

This......one thing I've learned is that non-standard ARs are not standard

Spinta sending one of their FP. I guess I assumed there was a standard for 9mm pins. If it works, I'm gonna get several more, just in case.

Spinta sent 2 FP. No failures. Spinta CS was very helpful and prompt.
