If it was installed with Rocksett just leave the muzzle submerged in a jar of water overnight.

If it's frozen, DO NOT attempt to remove it without a barrel vise. You can usually get away with removing muzzle devices using a vise block or reaction rod, but if it's frozen on there for some reason you're going to run a serious risk of unthreading your barrel from the extension.

Yep, barrel vise.
You could try to make your own, but the key is having a vise. |

$250 for a barrel vise!??????
We must have different defintions of what a barrel vise is. Presuming one already has a vise, work can be done with rubber mat thru aluminum angle. |

Quote HistoryAnd if you put the wood blocks in a shop press they’ll just split. You need steel blocks in a barrel vise, with either a jack or bolts. If it’s just an AR FH you can get away with aluminum blocks, maybe even nylon. But definitely not pine. |

This is when having a pinned A-frame FSB is great, since it's easy to clamp in a padded vice.
Spray penetrating oil at the suppressor threads, and let it sit an hour with gravity pulling the oil into the threads. Then clamp the barrel as best you can in a padded vice, and heat the suppressor with an oxy-acetylene torch. The penetrating oil will catch fire, but NBD. Keep the flame off the barrel to prevent discoloring it. Unscrew using a wrench. |

Home made wooden barrel clamp worked for me.
I agree with the soaking in water with the assumption that Rocksett was used. I just took one off an just set it barrel down in a bowl of boiling water for about 15 minutes and it came of fairly easily. Not sure if hot water helps but I figure it wouldn't hurt to get it to soak into the Rocksett faster. |

Barrel clamping blocks in my bench vise.
Just using the receiver clamp pieces in the vise scares the hell out of me (looks like something is going to slip or break.) |

Line your barrel block with paper or cardboard and it will prevent spinning and help grip the barrel without damaging the finish. The trick is to get the vise tight and using the right size of barrel block. I sometimes have to hit my vise handle with a rubber mallet to get it tight enough.

Clamp two pieces of 1x stock with a piece of cardboard or tag board in between to space them apart slightly, then drill the hole centered on the cardboard. That way you can clamp the barrel without the blocks touching each other and the full clamping force is applied to the barrel. |

There seems to be a pissing contest over what is the best way to clamp a barrel. I’m not wading into that mess, but I will say you want something that directly clamps the barrel.
You do not want this, nor this, or this. You’d stand the very real possibility of unscrewing the barrel from the extension. Those tools serve a purpose, I own each of the three, but they are not the right tool for this project. |

I have a bench vise, so I took an old leather belt and cut two pieces the length of the vice jaws. I gorilla glued the leather pieces to my vise jaws. I'll put some powdered rosin on the barrel and then tighten the vise jaws. With enough rosin and the jaws nice and tight the barrel won't spin.

Back in PA I had acess to an old vise it looked like a Prentiss BULL DOG Bench Vise No. 53, never had anything slip in that vice, as a kid I ruined more parts with over clamping than I can to admit. You just don't see these for sale like the old Parker or Prentiss anymore,
as posted always clamp closet to where you are working, I've used hard maple for blocks and crush the wood to fit or I'd cut a set of V blocks out of hard maple. Using any kind or upper receiver block clamping fixture for muzzle work is just asking for trouble. |

Quote HistoryQuoted: This. Did you figure it out, OP? @abnk Even what you possibly linked I'm wondering if I could twist the barrel. That flash suppressor is on there, and no it isn't pinned. I can see carbon like concrete built up on the sides where it meets flash suppressor to the throat of the muzzle. It's why I'm wanting to take the flash suppressor so I can clean it. I'm guessing it's build up from the crappy foam cleaner I was using and the carbon from the suppresor. I switched up barrel cleaners. I'm now using Bore tech eliminator which is amazing! |
