| What is your go to trick to remove a flash hider. I am having a hard time on most of them. |

Why professionals choose Rocksett: Heat resistant up to 700 C Metal-safe - Won't damage threads or cause corrosion Do not need heat to cure No mixing or priming required What makes it different from other threadlockers: Water Soluble Hot water soak releases the bond in minutes Precision application Just a few drops secure most threaded components |

If it’s just torqued on or held by a crush washer, a proper reaction rod works almost every time. Rocksett complicates things a little, and whatever crap Sig uses on their flash hiders is almost unbreakable. |

Aluminum barrel blocks, vise, wrench. On something like an XCR or an FAL, the gas block is chunky enough that I can forego the blocks, though I am still careful as to how much torque I apply (IMBEL FAL muzzle devices are notoriously tight). Use heat (or hot water for Rocksett, as above). |
Don't forget about the Trail of Beers Happy Hour!

My worst ones were the flash hiders on my Springfield Hellions. I ultimately had to pull the barrels from the receivers so I could clamp the gas block in a vice. The gas block is a pretty stout unit and secured to the barrel with two huge roll pins, so it wasn’t going anywhere. I soaked the flash hiders in penetrating lube for a few days. Then used a crow’s foot adapter on a 3’ extension bar to finally break them loose. I was convinced that gas block was going to spin.  I don’t know who is doing the muzzle devices at Springfield but between the Kuna and the Hellion they need to tone down the impact wrench a couple ugga-duggas.

That one looks nice too. They both look like they may be a bit too large for a 11.5. Not a ton of room on my 11.5 between the gas block and muzzle device. |

Not a ton of room on my 11.5 between the gas block and muzzle device. ~1 3/8"-2 1/2" depending on whether FSB or low profile. I'd seek a different option for an 11.5" definitely. |

(The $25 Bernzomatic utility torch style from Home Depot, nothing crazy.) Heat it up, get a cheater bar/extension, and hopefully it will come loose. Sig doesn’t use any thread lockers that I’m aware of but also have a reputation for excessively torqued muzzle devices. |

I use paper towels in hot water and a heat gun to get them hot enough. For Rocksett it's really the steam forced into the threads that breaks it loose. |

ProTip: Never pick a fight with a tree planter. He swings a hoedad for 9 hours a day, carries 30-40 pounds of seedlings on his back, and has 12-14 friends just like him hiding out on the other side of the junk butt pile. They will fuck your shit up.
