I believe my firing pin is gone/broken. Ordered a new one from Blackdog.
Anyone help with instructions to remove broken one and install new one? |

Quoted:
With a proper roll pin punch tap out the FP retaining pin. Clean out the hole, put in the new pin and spring, and tap the retaining pin back in. It's the transverse pin toward the rear of the bolt, above the right rail. Yes. Thanks - spotted it. Any experience on needing to swap out the extractor? |

I thought mine had broke as well but it turned out to be full of crude. The crude was causing light strikes. Dolomite Dontcha hate auto correct on phones? Crude? hahaha Yeah, it is getting annoying now that I have had it for a few years. It auto corrects to previous misspellings and it takes more time to go back and correct the auto correct than if I didn't have auto correct in the first place. I guess I need to contact BP about the problem as they seem to have the most experience in managing crude. Dolomite |

OK - so I decided to document my replacement in case someone else had to do it. It's pretty straight forward.
Here is my indication that the firing pin was the issue. The surface that the hammer strikes is gonzo. 
As frog5215 instructed, I identified the firing pin retaining roll pin. 
But, the pin should come out the extractor side as I spied a smaller opening on the non-extractor side.

After I used a punch, the pin itself was 'cruddy' - viola, a cleaned up roll pin
I used a punch to push out the broken firing pin. Note where it broke off. It's obviously the weakest point. The new one is nice and shiny. 
Reinsert the roll pin and all is well again. I can shoot cheap 22LR again.

Looks great. When I pulled mine out I decided to go ahead and replace it. I used a standard AR15 firing pin that I ground down the the same dimensions as the original firing pin. Since doing this about 4 years ago I have put well over 10K rounds through the kit without a single issue.

Dolomite I have limited access to machinery so I appreciate the supply of firing pins available. Anyone use the Lakeside spring kit? My springs seem to be okay so I didn't take that plunge. I have to say that due to Ciener's patent supposedly lapsing in conjunction with the high ammo prices, we're seeing some nice innovation in 22LR kits and fun blasters. |

Be a little careful. The Spike's bolt has the retaining pin up front near the extractor pivot pin, so the firing pins aren't the same. CMMG stuff is supposed to look like it came off the same tooling as Ciener. Ditto Armalite. True. Thanks for the heads up. Hopefully this is my last firing pin. |

I actually chucked the firing pin in a drill then used a bench grinder to contour it. That was definitely long before I had any of the stuff to do it that I have now. One thing I did do to help prevent the firing pin from breaking again was to leave a lip on the rear head of the firing pin. The lip was big enough that it would rest on the rear of the bolt to limit its forward movement. My thinking was that normally the roll pin keeps the firing pin from going too far forward and that is why they break at that location. With the one I made it stops on the firing pin's head. It seems to work fine. Thanks for the pictures, it will definintely help some people out. Dolomite |
