This is what my firing pin looks like after about 2500 rounds. It is so smashed in that it will no longer fire. Is the new or old design? And has anyone else had this problem?

WOW! Looks like it has been hitting something real hard. Primers are fairly soft (note the dent on spent case) What ammo have you been using? Wolf has steel cases, look at fired cases & see if primers are hit square in the middle. Mabe the aftermarket will come up with a titanium firing pin.

I have mostly been using IMI 55gr and 62gr stuff. Also I have used some PMC, UMC, & PMP stuff. Here is a pic of one of my spent shell casings.

It's hard to tell from the picture. Is there cratering of the primer and is the bright spot at around 4 o'clock a shiny spot or an impact spot?

Looks slightly cratered to me, but if that is a hit with the flattened tip, I wouldn't read anything into it. Personally I would just replace the pin for now and see if the results repeat. Maybe you just got a pin made of some out of spec soft material or something?

The spot at 4 oclock looks like the NATO stamp on the rim.

The picture of the casing is in center of the primer & is a perfectly round indention. It seems to me with the pitcher of the firing pin, that the indention would be less than perfect?

That is the old style firing pin.

I had a new style one that also got damage to the tip, but also broke. Call Robinson and email your pictures to whoever you talk to. They'll set you up with a new fp.


There still seems to be some issues with the firing pins. This was mine after ~400 rounds.



I couldn't figure out how or when this happened because I went through the breakin period with no trouble whatsoever, and after a cleaning the rifle it wouldn't fire at the next range trip. I'm inclined to believe maybe I dropped the bolt or maybe the fp broke during the extensive dry firing I did with the rifle to work on the trigger. Who knows...in any case I love shooting my xcr and it has fuctioned perfectly since replacing the fp.

Looking at that particular piece of brass. The shiny spot is shiny because of the light. It is a circle with two intersecting lines through it. For the primer it is crater. Below are some pics. Both are IMI brass. The casing on the right was fired out of my AR15 (looks normal) and the other out of the XCR. I have placed and order for a couple of new firing pins. Hopefully they should get here soon.





In this photo, the shell casing on the left is from the XCR when I first got it. The center casing is when the FP got smashed in. It was working intermittently at the time. And the casing on the right if from my AR15. All are IMI brass.
