Trying to take a brake off a DPMS threaded upper, IDK what is going on, thinking loctite was involved in massive quanities.... How the hell am I supposed to get it off??? any suggestions... I was thinking heat... but then I was also thinking about what heat and stainless looks like afterwards (blueing).....

doesn't have to get hot, just get a hair dryer to warm it up

Sounds like heat is our only option. Heat slow and only add whats needed. Maybe use a temp stick to make sure your not getting it too hot

There is nothing wrong with heat. It's a gun, its made to heat up

A hair dryer is not going to screw things up, try that first. If that does not work, soak it in very hot water. There are ways to safely heat it up without putting a flame to it

You don't need to get it so hot it blues. Locktite will soften around 300 deg.

Is it a pinned brake?

Mostly for my own sanity, I gotta ask...are you turning it the correct way? Barrel threads are left-handed instead of right.

only for some guns. Most muzzle threads on domestic designs are going to be RH.

Just use some Mother's polish to remove the blue. There's also blu-away. All this is VERY commonly done on stainless headers, so don't worry.

If you are careful with the heat and observant, you can actually see a wisp of smoke and smell it when the loctite cooks off.

Dry ice on the barrel, heat gun on the brake, should come right off. Don't be afraid to use some strength, you aren't going to twist the barrel (just don't use one of those cheesy upper receiver vice things that hold it by nothing more then the pins, use a good barrel vice insert).

Are you using a barrel block and a vice?

YUP, OP never mentioned if it is a 14.5 , 16 or 20in barrel.

IF its 14.5 that break is permanently attached.

Check that first.

And regarding loctite, considering that it's on the barrel, it'd probably break down anyway due to the heat of firing. Most muzzle attachments use a crush washer and are torqued down.

Step one Apply mild heat
Step two Apply the best break-free ever made! mix 50% transmission fluid and 50% acetone.
Step three Put it in barrel block and a vice.
Good luck - cowboy

I've had to put a barrel on the stove to get the brake off with a rag and a wrench. Go from easiest to hardest: Oil, solvents (check your finish FIRST), mild heat, more heat.
