I have a mod 1 that's a few years old. It has a definite gas leak between the gas tube and the gas block. Does anyone have and idea how to fix it or if I can contact knights to send it in to be fixed?
Thanks! |

I would send an email to KAC and see if they will provide a RMA ([email protected]). Conversely, either D. Wilson or NS Armory could probably look into the issue for you.

How bad are we talking?
Some blow-by is normal, although it usually limits itself once enough carbon has been deposited to seal any gaps. |

I don't know if its consequential, but there is quite a bit of carbon deposited on the gas tube, and the barrel right underneath the connection.

Is it having any function issues? If not, that connection isn’t air tight. It’s a tube inserted into a hole that’s held in place with a tiny roll pin. That tube is seeing tens of thousands of PSI every time you pull the trigger. Some stuff is going to get by. |

How many rounds through the gun?
I’m having a bit of a hard time deciphering what’s what there. Is there rust or spray paint in the mix? It looks really reddish brown under there, with only a little bit of black and some greenish oxidized copper. |

A little leakage is to be expected, and is accounted for in design.
If you aren't short-stroking, it's fine. |

I have an well used Mod 1 upper and it definitely leaks a little bit (as well as being over-gassed a little). Seems to still be going strong though (I use an H2 buffer which tamed the overgas nicely).

That might explain why it's been a while since you sent your email. Hopefully they get to you soon. https://www.ar15.com/forums/armory/KAC-PRT-Suppressor-Recall/64-544740/&page=2 |

My CS guy just got back from vacation yesterday and is wading through about 6,825 emails on this recall, so it might take a minute to get a response. That said, I addressed your question: if you aren't seeing indications of short-stroking, it's fine. |

Oh yeah I forgot about the recall, this is no rush or anything, and the only issues I was having were under really adverse conditions obviously. Ill just wait until they get to my email.
Thanks! |
