White paint pen, which I use to witness mark most of the critical clamping interfaces (bbl nuts, optic mounts, etc).
The color will fade a but over time but I've never had to re-apply it on any of my muzzle devices, including those that have seen a ton of suppressed fire. |

If it moves, you’ll see it, and no way it will make a full rotation and still be tight enough that you can’t wiggle/rotate by hand.
It’s a non-issue. |

I don't, but I manly use the Smith Vortex which keeps itself tight just from shooting.

That said, I used a silver Sharpie to mark barrel and gas block for an install about a year and a half ago, and when I was working on the gun last week I noticed the marks had held up through a lot of hard use, rain, mud, etc. Granted that's under the handguard but a simple sharpie mark will probably do what you need. |

Quote HistoryQuoted: I'm with this - if you are paying close enough attention to check marks, I'd think you would notice if the device itself was rotating. Rocksett and torque, and you won't have to worry in the first place.

Hell, I’m using shims and anti seize, very minimal torque. That’s begging to come off. Still on there. I don’t think I’ve ever heard of a properly installed muzzle device coming loose. |

Antisieze doesn’t make stuff come loose on it’s own, but it does make it get tighter when applying torque. Look into lubricated vs dry threading.
I put them on gutentight, no problem. Never had a lugnut, flange, etc come loose from antisieze either. |

Torque it down correctly, and there's no reason it should loosen.
We've been doing threaded fasteners for a long time now. It's not rocket science. |

Provided your barrel has a good "shoulder" for the shims/crush washer/etc... a properly mounted muzzle device shouldn't come loose.
I have seen poor "shoulders" on some barrels that don't have enough "area" for the shims to connect with.... ( be VERY careful if you decide to install a suppressor on the bad "less then flat / enough area shoulders of some barrels.. Baffle strikes from poor alignment ) and that has been corrected with a Surefire "SCAR 17" shoulder ring. Those bad shoulders can be problematic... and loosen more easily then a "good" ( decent contact area. ) shoulder. I used some of the SCAR 17 shims on 308 and 6.5CM barrels with poor shoulders. https://www.parkermountainmachine.com/store/p113/Surefire_SCAR_17%2FMK20___Shoulder_Ring..html Or... https://www.silencershop.com/scar-17-shoulder-ring.html Or... https://www.kbacustom.com/our-products/firearm-accessories/product/34-scar-17s-muzzle-shoulder-ring.html |

The whole "mark everything with a marker to make sure it is not moving" thing makes some sense on an optic mount if you are literally jumping out of helicopters and having artillery rain on your head, but has mostly become a "copy the HSLD guys for cool points" thing....there is definitely a thing as taking it too far.
Torque to 25 foot lbs with a crush washer, or "a quarter turn past initial resistance" and move on with your life. Sven Manticore Arms |
