Had a thought after some fun getting Rocksett off of a muzzle device the other day. What’s the point? Given a torque of 25 foot pounds, no amount of vibration is going to twist a muzzle device off. Thus, no need for Rocksett. On the opposite end of the torque spectrum, if a fastener is only supposed to be torqued down to a low inch pound number, then Rocksett is too strong anyways. Therefore why Rocksett anything? High torque fasteners are held on with torque, and low torque fasteners are too weak to survive the Rocksett removal process. |

I've witnessed MD's torqued beyond 25ftlbs come loose from shooting. Rocksett removal should have zero impact on what torque the fastener was set at, hi or lo. Rocksett is so simple to use, there's very little down-side. I don't use it everywhere, but it is on every MD I use. I also use it on the rear cap of every silencer I own (that isn't welded or otherwise fixed in-place). Eta: Even Surfire uses Rocksett and torques their MD's beyond 25ftlbs |

Quoted: It's not meant to hold like retaining compound. It's absolutely designed to perform as such. It's a thread-locking adhesive. Directly from flexbar's website: "Rocksett is the #1 Adhesive for use on Threaded Gun Components Muzzle Brakes, Recoil Compensators Suppressors, Vehicle Exhaust Bolts." |

Understood, I was referring to the hold strength. I should have paid better attention to the original question. |

1. At 25 lbs I've twisted mounts off with suppressors. Target market is suppressor users, hence the high heat resistance. Otherwise it doesn't matter. 2. I have never struggled to remove a rocksetted device. Soak it in water and it will come right off. You should only use a drop or two. But even when its overdone I've gotten them off with little issue, but you have to let it soak... Trying to remove it without water is like trying to remove something fastened with red loctite without applying heat. |

Yeah put the muzzle in water over night, the muzzle device will come right off. Rocksett just dissolves away. Easy as can be, better than stuff that breaks down under heat like loctite formulas. I only use Rocksett for suppressor mounting flash hiders. Regular A2 FH’s just get the crush washer as per normal. |

It’s for suppressor mounts so you don’t torque the muzzle device off the barrel with the can. If you’re not using a suppressor, I’m not sure why you’d bother, nor have I heard or seen anyone recommend it’s use outside of that application. I’m gonna guess this is more a case of OP not being familiar with the use case for Rocksett. |

I really learned something here, re: Rocksett for suppressor-mounting muzzle devices. Thanks all for sharing this. It seems I'd be wise -- or at least not foolish -- to incorporate this step into my suppressor-host upper builds from now on, and add it to some of my current uppers. |

Don't heat it, though. |

Quoted:Rocksett doesn't handle shock well. Many times one can simply clamp the barrel, put a wrench on MD and smack the wrench with a hammer. They'll usually spin right off. Rocksett handles vibration very well and its resistance to this is incorporated into its design. It wouldn't be marketed towards muzzle devices, and firearms in general, if it couldn't handle an appropriate amount of vibration and shock, and it's reputation wouldn't be what it is also. You're assuming the assembler always used the recommended procedure for installation. I've attached threaded joints with Rocksett, per Mfr recommendations, and tested breakout torque. On something that was applied with, say, 25ftlbs, I could definitely see it breaking at ~50ftlbs. Yes, a hammer blow to your wrench could do this. However, did the joint fail due to vibration (in the form it was meant for) or shock at a torque value greater than necessary for the intended purpose? The forces a silencer applies to a mount are not the same as you whacking a barrel wrench with a hammer. So, no, I wouldn't expect Rocksett to act the same. |

Even if the overall force isn't much higher or the same, the impulse is much greater than pulling with your hand, right? -- That is to say, any energy transferred is over a shorter period of time with the hammer whack than pulling a wrench. But, as you said, forces applied by a silencer are different -- primarily linear forces, forward and back, as the gasses expand in the suppressor (pushing threads against each other) and heat. A wrench is applying rotational forces (rotating the threads past each other). So, that is drastically different. |

It's a ceramic bonding agent that withstands high temps and protects against vibration. It is not shock/ impact resistant. Shock will break the bond. Or sit and wait for it to soak. I'd rather not soak my barrels/MDs in water....but to each their own. |

Quoted: Thanks all for the replies. Suppressors seem like the main reason, then, and even then just as extra security. There's a reason that most manufacturers/ vendors include a statement such as this in their descriptions: •Make sure all surfaces are cleaned and the muzzle device has been torqued and Rocksett to the barrel OR •It is extremely important to torque and rocksett your muzzle device to the barrel properly. |

Having removed quite a few Rocksett suppressor mounts, enough torque will do it; it will take way more than used to put it on. Still not hard if you have the right tools. I started worrying about spinning a barrel extension, and recently I've been soaking them in near boiling water for 25 minutes, and they come off pretty easy after that. In terms of "shock", if firing a shot isn't enough shock, I don't know what would be. I've never had an issue with them breaking loose until I wanted them to. I clean all the threads very well before installation. I use it only on suppressor mounts. If you don't plan to mount a suppressor, you definitely don't need it, and should probably be using grease instead. |
