Too late, I fired them from my rifle. We are taking a skill builder on Sat and I will be running the same case of ammo (Federal XM193).  For the last skill builder, we both ran the same ammo case and I had no light strikes.  I'm pretty sure it was the cracked bolt.  See above clicking reference.

Doh. No focus. That’s the bolt?  Yeah. That’s probably the problem. Lol

The bolt was pink/purple.  It was ashamed to be in such an oppressed operating conditions.

Picked up the CMMG bolt today from DCT. And will run this saturday's skill builder. Didn't have a go/no go gauge, but got a spare BCG just in case.

Go no go with cmmg bolt passed. Had to YT, i left the extractor spring thing in (no focus).then had to YT which end the plunger goes in and what direction.

So what?  New bolt/bcg solve the issue?

Yup, no issues.  Both new bolts passed the go/nogo test prior to shooting.  So at least now I got a spare bolt.  Was gonna get a spare BCG, but decided to save my money for a new CCW gun.

Spare bolt will likely get you pretty far.  I've never seen a BCG fail, other than non-staked or poorly staked carrier screws/bolts backing out.  Keep an eye out for sales, usually near holidays for spares.
