Can anyone provide me with info on the best way to polish the chamber on my DPMS 308???
Thanks. |

I polish all my chambers, it makes it easier to keep them clean. I use a chamber mop on an old cleaning rod I cut down with a lot of Flitz polish and a variable speed drill at it's slowest setting. If the chamber has any marks after polishing show it to a gunsmith. That's IMHO.

Iosso is a little quicker, the mop needs to fit pretty tight in the chamber, be sure not to let it go in to the neck or throat and damage the lands.
Production barrels are just cut with a reamer but, if a smith does a custom chamber right it should be finished with 600 grit for an AR. |

Quoted:
Is the chamber chrome lined? I'm guessing you won't be able to polish it if it is. If it is not chrome lined, polish it to much and the law of unintended consequences is going to rear its ugly little head... No, not CL. Just like the idea of a little polish job to make cleaning easier. There is alot going on in a big cal. like 308 when you pull the trigger. |

I don't know about BEST. But this is what worked in my old DPMS .308.
Get a .410 Mop. Use some Dremel polish compound. Use variable speed drill. Insert into chamber and polish for about 30 second about medium speed. Clean it all out and repeat. I did this and my chamber was nice and shiny. Rounds came flying out of there like a scalded ape. Made cleaning easier too. YMMV |
