Cases get stuck after firing and won't extract, but comes out easy with a cleaning rod (when cold).
It has already gone back to the manufacturer once and it still does it. Recommendations? Polish the chamber? Thanks! |

What model rifle is it?
Check the fired brass for frosting on the case body and particularly the neck. If it's frosted, it needs polishing. |

Chuck a bore mop that fits tight in the chamber in a drill and coat it with polishing compound.
Insert and run the drill. Clean the chamber, repeat as necessary. |

The neck is usually the culprit on a sticky chamber. But be really careful going that far into the chamber. Going into the throat and leade can fubar your barrel.
Tread lightly. |

Try some flitz. Nothing too aggressive. Run it in a drill with a mop.

Safety Harbor?
My bolt action SHTF upper did it with the black box American Eagle XM33 but nothing else. A know someone with one that did it with that, PMC, and some other ammo. They polished it with a flex-hone, it stopped doing it, and paradoxically slightly improved accuracy. YMMV. |

You may have a tight chamber when i bought my riffl I could choose one of 3 chambers a match chamber but was a hand load only option, a military cut chamber that was a little oversized but could shoot anything and finally the third was a in between. I chose the latter option. When i shoot surplus ammo I get sticky cases. I need to use cleaning rod to tap the case out but my hand loads come out very easily. I do not run my hand loads as hot as military loads.
Could this be similar to your issue? |

I had a brand new Safety Harbor do the same thing. I returned it and, with a one month turnaround, the issue was only slightly better. I fixed the problem by getting an AR-50. |
