this came out of my AR308 in 6.5 Creedmoor. Strangest thing I have seen in decades of shooting ARs. It is sitting next to a new spare pin to highlight the difference.
Ever see a bent firing pin in an AR?

How many cycles?
Maybe a heat treating problem? Metal might be softer than spec.

You just can't win on the Internet today can you?
Weird. Good thing they are cheap and easy to replace huh? Makes me wonder if something else in the gun is out of whack though.
Ehh the gun functioned flawlessly. Shooting it you never would have know it had a problem. It has a lifetime waranty from Brownells so I just stuffed a spare BCG in the gun and am awaiting an RMA from Brownells it pays to have spare parts.
The only thing that hits it is the hammer. My bet is it is a badly heat treated part.
What I was wondering was if the hammer hit the pin while out of battery.......... but I can't imagine there is enough power in the hammer spring to do that bad heat treat or not. The rear of the firing pin does not contact the hammer when the BCG comes back correct?
Nope it doesn't.
Thats just plain weird if you ask me.
Yeah I have been shooting ARs for 35 years and have never seen this before.

A reminder that 2 is 1 and 1 is none. Backup rifle or spare parts any time for a match or shoot.
I have a little compartmentalized pouch strapped to my range bag, in it I have a spare bolt, firing pin, gas rings and batteries. Plus other small misc stuff. I'm thinking of getting a whole, complete extra BCG for ultra rapid range fixes.
Yep learn it, live it, love it. Murphy is always around to make you pay for being ill prepared.
Funny, I bent a retaining pin today while cleaning my AR-10. Ordered 3 from Palmetto because A) I want three and B) the damn shipping was 3 times the cost of one!
It was a brownells brand part so who knows.

My money is on bad heat treat as well. I just cant see a pin like that bending if it was hardened properly. If it was I would think it would be more likely to crack then bend.
Or Brownells supplier is building out of substandard metal and not heat treating.

Brand new out of the package 36 rounds on the BCG assembly.

Then expect to see more bent pins?
Brownells just called me, they are 2 day shipping me a new BCG and sending a call tag for the other BCG. She said she is doing a good faith exchange to get me up and running sooner. Talk about good customer service!
New BCG arrived today, I will be sure to put it through the paces next weekend to make sure I didn't get another lemon.
