Bolt issue

[Lazyfaire]

So I was at the range a month ago and my (AR) cartridge would fire but it was not extracting. Brass was still in the chamber but expanded so I had to stop, get the RSO, and hit the buttstock on the counter to drop it right out. That got tiring quickly.

Swapped out the BCG and then no problem.

Took it all apart last week and found the problem.
The bolt was a 7.62x39.
I have never owned an AK nor bought a used bolt from anyone. WTF?! Can only guess it came in a complete upper I bought some time ago. Pretty sure I will never know.

That's impressive.

Nope. 5.56

One of those things that will never be explained. Luckily no harm no foul. Good tight fit with the bolt precluded a blowout. But having to empty the chamber every time made me check it out sooner than later!

I could use a spare 7.62x39 bolt. If you care to part with it, send me a PM.....

I think you could have fixed it with extended extractor claw

Meh! Going to use the BC for a 6mm ARC anyway. Its just one more thing laying around anyway

I was just kidding, glad nothing catastrophic happened.

You're not suppose to do that.

??? The bolt for the 6mm ARC replaces an AR-15 bolt. Same size, different face. I contacted Primary Arms about it.

William Andrews sent a message Jun 9, 6:06pm​ William Andrews Other [email protected] Re: converting to 6mm ARC I know that the bolt itself is different from a 5.56, but is the bolt carrier the same? Can I use a 6.5 Grendel Type 2 bolt in a 5.56 bolt carrier? O must I purchase a whole new BCG? Thx Bill Andrews

A primer misfire might have not been fun tho

I was responding to the OP, 7.62x39 bolt in a 5.56/.223 gun.

Glad the issue was found before an accident happened.
