I would try a heat gun first (sold at home repair centers for removing paint). No flame, but a lot of heat - enough to char wood if held close. Much less chance of ruining finish on gun.

Heat is usually the best way to get red or green loctite to let go, and I agree with Buntlineguy to use a heat gun. They're available at the hardware store for a reasonable price and they're good to have around for all kinds of other tasks.

Soak it with Kroil or Breakfree etc, then use the heat gun on it. The hot air will get it plenty hot, but not so hot it changes temper, chars finish or distorts metal like direct flame.
Keep the heat on it until it gets hot enough the solvent you used starts to boil and smoke. (This would be best done in your ventilated shop or garage and not in your wife's kitchen)

It 'should' break free. (Let us know)

I would use a propane blow torch. Just don't get too crazy with the heat. A little bit goes a long way. Have someone there to help with the wrench and once it starts turning, don't stop until it's out.

I think Bill's right. Just heat and use the correct wrench. The part was made to stand up to high heat. It doesn't have to be cherry or anything so what's wrong with direct application? Red locktight isn't concrete, just a bit of heat and it gives...

Bill, the Tool Man Taylor! More Power!

A torch works too and gets hot quicker. As Bill said, just go easy.

Whichever you use, I think the heat breaks down the loctite and may expand the nut a little. I worked in a motorcycle shop all through high school and college, and it seemed that many people thought they had to red loctite the snot out of everything. (Sometimes they brought things in just because they did use loctite and wrecked the nut or screw head trying to loosen it)

[Bill Hollinger]

come to think of it, I rather doubt you could get the barrel and gas cylinder too hot with a propane torch.

[Harlan (Deceased)]

Probably not, Bill and a propane torch should work fine. I just thought of the heat gun because open flame sometimes has it's drawbacks.

Fungun1, let us know if it works.
