Do not use a Viton o-ring. Viton is chemical resistant, not temperature. Silicone has a higher temp rating than Viton.
You need to use a precision shim kit. |

Please don't comment on things you know nothing about. Viton o-rings are rated to handle temperatures up to 400° F. Yes, they are also very chemically resistant, but they are the primary go-to material in many industries for high heat applications. Light duty auto transmissions, for one. |

Quote HistoryQuoted:Please don't comment on things you know nothing about. @intheburbs I design industrial oil and gas burners. I'd say I'm well enough qualified to comment on this subject matter. The muzzle of a centerfire rifle can get well above 400F. An o-ring is not the proper piece of hardware for this application. That's what precision shims are for. |

or you can run the FSB side of the device across a flat file or stone to remove small amounts of material until it makes one more full rotation and tightly times up with the detent.
if you don't plan on swapping the device to another rifle imo this is the best way to go. don't need to worry about o rings or shims |

Exactly how I do mine, easy-peasy. On an AK or other rifle that doesn't have the standard FSB of a regular AK, I sometimes use a small wrap of teflon plumbers tape, works perfectly, over time it'll get a little crispy, when it does you just pull the muzzle device, clean threads, apply new tape. This is literally a penny fix that works like a charm, tape acts like a threadlocker. |

Now who is commenting on things they know nothing about. 400 degrees is NOT high heat. Surefire sends a small tube of Rockset with every muzzle device they sell. Use google and become enlightened. |

OP if you have the detent in the FSB, then file the back down if you feel you need a tight lockup.
If you do not have the detent, then I guess follow what else these other people are saying, I've never bought one w/o |

Is this really how it's done? Do the comblok militaries do this? I'm not trying to be snarky, asking an honest question because two of mine fit loose and it drives me nuts!! |

No, the combloc militaries installed device and said, eh, is good enough. A little rattle ends up going away with enough carbon. |

Well like Nictra said, no they don't, but they ought to, it's so simple and quick, piece of sandpaper, flat surface, maybe 30 seconds total of elbow grease and bam, custom perfect fit. |
