I just installed the 10.5 with factory installed switch block, when the bolt slams in and the lock lugs turn to fire, round goes off, but lugs are bolt lugs are stuck on the lugs in the extension tube. Is that a head space issue, no damage on the gas tube, cam pin is on corrently
When I slide the bolt in it locks and unlocks fine, only locks up my carrier when a live round is in there. Any suggestions? |

Lets try this again.
Bolt lock up fine on a live round, Round fires fire. But bolt will not cycle back and eject the spent case? Did the bolt try to unlock at all? If yes, then you need to check the gas system. As for hard to extract the spent case by hand, If the bolt did start to cycle, but just pushed the spent round back in and lock the bolt closed again, it going to be a bear to extract the spent case. |

Get a few hundred rounds of the rifle self cycling through live fire to allow the lugs to mate out/self polish against each other, then you can go back to locking the gas system closed. |

As for if you are going to turn the rifle into a single shot by turning the gas system off, make sure that when the gas system is off, that no gas is getting back to the bolt. If the bolt lugs unlock from the barrel lugs at all with the gas system shut off, then you will be back to pogo'g the rifle to get the bolt to unlock. Again, if the bolt unlock at all, and the spent case is driving back into the chamber, it going to be a PITA to get the bolt unlocked. |
