Gas rings lined up after shooting
Hello all,
I took my PA10 to the desert and shot about 150 rounds and when I was cleaning it today the gas rings were all lined up. I know 100% for sure I had them separated into thirds before I started shooting. Does this indicate a problem with the gun and is there something I can do to prevent it? Thank you

The gas rings rotate when you fire the rifle, so I don't think there's an issue with it. After cleaning, you can separate the ring gaps again if you wish.
FWIW, my AR functions fine even when ring gaps are lined up. I still stagger them though after cleaning. |

It’s not a car engine where blow by pressurized the oil
It still worked at the end of the day? Right?

Don't give your gas rings another thought until they start to wear out. GAS RINGS LINING UP DOES NOT MATTER. |

As a former US Army armorer, gas rings were never an issue until they wore down. I also took an Armalite armorers course and the instructor was clear - don't worry about the gas rings lining up.

Don't worry, someone else who was in the Marines (and not a lowly reservist like me) will be along shortly to tell you how their DIs used to beat them for lined up gas rings and how an entire squad was killed on the rifle range when a boot PFC lined up their gas rings on purpose.
USMC is not always the hyper-professional gun club everyone thinks sometimes. Our DIs used to have us use the firing pin to grind away on the crown of the bbl to make it shiny for inspection. So either they somehow didn't know jack about the importance of the crown, or the conventional wisdom about the importance of the crown is BS. I am betting on the former. Or maybe they just placed more importance on a shiny crown for inspection purposes than on the health of fleet hand-me-downs with 100K rounds through them. Suffice it to say, later on an armorer saw me doing that and lost his sh*t on me. |

Ok, now I have to say it. My friend in the Marines (has since got out) showed me how to clean my AR when I first shot it. Yep, used the firing pin to clean the carbon off the part where the gas tube goes in (is that called the crown?). I assumed the firing pin must me super ultra hard metal that can scrape diamonds away if needed. Anyway, I don't do that, I use a razor blade to scrape stuff off. Do the guns that have 100,000 rounds through them have original barrels or do they at least swap those out?

Don’t worry about it. It absolutely doesn’t matter. They move with use. There’s no way to keep the ring gaps staggered in actual use. What matters is that they aren’t worn out missing or broken, and even then AR’s tend to continue to work. I can almost guarantee with 100% certainty your rifle would run with just one gas ring. I’ve seen some worn *** gas rings on dudes duty rifles and they still run.

Judging by the bare metal shine of the barrels from years of nasty recruit hands doing manual of arms (left shoulder, right shoulder, etc) I'd say about the only thing that ever got replaced was the odd handguard. |

Yeah that's more or less the issue. It's the last contact with the bullet so the premise is that if it's not even then the gas escaping behind the bullet as it is barely out of the barrel will escape unevenly and put some wobble to it.

I'm gonna look at mine when I get home. Now I am curious.

We did this is a carbine class lead by a retired ODA guy. Ran perfectly, no issues.

I never looked at them other than cleaning never been told to check alignment or anything like that. They will outlast your bolt thats for sure.
My old roommate was an Armorer and he said that most rifles would go through 2 or 3 barrels before ANY other parts were changed. He worked at Infantry training school and 5th Marines so he saw some guns with heavy use and some abuse.

Agreed, it's not a problem.
IF it bothers you, you might check to see if there are any burr's on the ends that might keep them from rotating independently. A little stone work would correct this. |

No, I don't care, if it doesn't affect performance I don't give a darn
