THE IMAGE ABOVE IS A PAID ADVERTISEMENT Put upper in upper receiver block/vise....wrench FH off? ....Or is there a Barrel vise?? PROBLEM: Im running a Larue 13.2 on a 16" barrel...Cant really secure the barrel....and I dont want to put harmful force on Barrel nut/ receiver but wrenching on the FH while Receiver is in vise.... Is that even a problem??? Is there anything I can soak my FH in to make this process easier before I start? What would be the proper procedure to do this job? ....Dont wanna ruin it 
Thanks E |

Take handguard nut off rail and slide it off. Shouldn't need to remove the barrel nut. Clamp barrel in a set of barrel vice jaws.
Can't help you with the rockset. Never used it. |

How do I keep from damaging barrel from vise jaws? Tape? Aluminum? wood? clamping the barrel down tight enough to not move under such torque wont "crush" the barrel (for a lack of a better term) will it?

Rockset is about as strong as blue loctite, just MUCH MUCH MUCH more resistant to heat which is why it's used for suppressor mounts. It should just break free with a minimal amount of torque.
If the FH is being a real PITA, Rockset is water soluble. Soak the muzzle end in hot or boiling water to loosen up/dissolve the adhesive. When you break it free, spray down the muzzle threads, FH, and bore to remove any excess water and allow to dry fully before reassembling |

Many in the same boat simply soak the flashider in water overnight and it comes off easily (for most).
Locktite's break down and give up around 500 degrees. Rocksett loves heat and is more resistant. (around 1100 degrees) If you cant break it loose with a sharp blow from a good fitting wrench soak it and try it. |

Rocksett Dissolves easily in boiling water. Boil water, put your muzzle in and get to removal tool before it cools.

Do you not understand what would happen if someone cranked on one with a wrench that was real tight and had red Loctite too? Your advice is bad, I don't care how many "get it done that way". |

Your advice is bad, I don't care how many "get it done that way". What would happen? I have seen a upper reciever crack doing it your way I wached a barrel get twisted because the barrel clamp was a foot from the muzzle end of the barrel and when you went to use the iron sights the front sight was way off because of the twist. |

Lots of good advice here, you might want to consider some Rosin, or I've heard reccomended but never tried, damp sugared newspaper in the barrel vise to prevent the barrel from slipping or marring.
The aluminum wont "hurt" the barrel, but if it rotates it can transfer aluminum onto the barrel, which is a PITA to remove. As stated, clamp as close to the Muzzle device as you can, you don't want your barrel to be a torsion bar  |

As stated above, Rockset will almost completely dissolve in water. Soak it overnight or at least for a couple hours.
Normally barrel vise blocks would be preferred, but because of your rail situation (the LaRue 13.2 won't come off to expose the barrel because the AAC flash suppressor is larger than the rail's inner opening) just use an upper receiver block and be GENTLE. |
