Thanks to all those helped. I didn't realize that so many had an extra bolt. I got like 4 messages.
I had DCT order me a CMMG bolt becuase Mrs. CMO needs it by next Saturday if she gets into the HDF combo skill builder. David said he can get it by next week. And if not, she can borrow 1 of his bolts. He will also do the go/no go check. I could get it for cheaper online, but I want to support him since he did so much for the 2A (online registration, just to name 1 thing).
Since so many have extra bolts (a few have 2+), I call that a clue. So I ordered a BCM bolt, cam pin, and extractor/extractor spring set from BCM as well. IDK how long it will take to arrive. I have a firing pin somewhere at home because I bought 1 when I first got my AR thinking it would eventually break, which now I know is super rare. Funny thing is the plan was to put it inside my compartment I have on my Magpul butstock, but it doesn't fit. At least I can put an extra battery for the red dot in there and hex key for the red dot.
B4 I disassembled the BCG, I played with the firing pin and it made a click every time I pushed it to have it protrude out the other end. So I compared this to my M&P15 BCG and there's no click. I also had to push way harder compared to my M&P15 BCG firing pin.
The interesting thing will be to see if the new bolt fails so soon again. Because then we know it's another issue. But this failure took about 4-5 years. So I'll have to update everyone way later if it happens.
