My bolt carrier thought it was too hot out today, so it decided to give itself a vent hole. The hole is a about .125" in diameter. Just big enough to let the bolt eject the spent case but lets out too much gas to push the carrier far enough back to strip the next round or lock the bolt open. Surprisingly it is a very clean hole though atleast .290" of metal. It is through the thicker part of the carrier between the firing pin and the gas rings on the bolt. No other damage to any other parts, just this nice clean hole. Any ideas what could have caused this? Bad photographer = Bad pics   Is a full auto carrier stronger than a semi? |
It won't cycle completely because of the hole so it is garbage anyways. I won't try to fix it and have it fail and injure myself. I have better pics coming in a few minutes |
Maybe a hole was drilled off location and then plugged, and the plug blew out I have seen some strange things working in machine shops over the years, especially on parts and components that aren't aerospace (ie if it breaks nothing crashes from the skies!!).....

Just kidding. Glad you were not hert, that is strange.
