Just got my spare complete bolt / bolt carrier group in the mail last week.  I took it apart and checked everything over, all was good.

Today I popped it in and fired a couple hundred rounds with it.  Everything worked flawlessly.

After firing I started cleaning and noticed the firing pin was difficult to remove.  When I got it out the front portion of the firing pin was sightly bent.

Wht would cause this?  Is this just a "shit happens" situation or is there anything I should check out?

Thanks in advance for any advise.

Who is the manufacturer?  Sounds like the firing pin wasn't properly heat treated.  Either that, or it was bent during the manufacturing process.

It is a CMT/Stag from Global Tactical Supply.  It wasn't bent when I received it.  I happened while firing.

Yep thats not normal but I think you knew that.

Contact the seller and they will usually make it right if you are civil.

It's always a good practice to have spare parts on hand in the range bag/gun case.

Firing pins range from cheap to expensive so you may as well pick up an extra at the next gun show.

So it was probably just a bad firing pin,nothing to worry about anywhere else?  I have extra firing pins already.

Did you look at the condition of the primers on the discharged cases? Probably not the case here, but excessive firing pin protrusion comes to mind. Might be something to consider.

One check to perform before using you weapon again.
Straighten the bent firing pin as much as possible, so it can be slid into the bolt.
Remove the bolt from the carrier.
Place the firing pin in the bolt completely.
The shoulder at the rear of the firing pin should contact the rear of the bolt and have the correct protrusion at the bolt face.
If the shoulder of the pin does not make contact with the rear of the bolt, it is too long, and is the reason it is bent.
You can check the replacement pin the same way.
If it also does not make contact with the rear of the bolt, your bolt most likely is out of spec. and needs replaced.

To expand on where I was going, and to add to what Walker_18B just posted.
