Gunsmithing APA Fat Bastard stuck... any recomendations

[Safety_3rd]

I feel like a little b$tch. I have a self timing break on my 338 lapua and recently picked up a thunderbeast can. I have been able to break the collar of the break free but it appears that the part that threads directly to the barrel has seized. I dont really want to mar the break up, or stick something through the ports because I dont want to bend the metal in there. Any other suggestions? Thanks in advance.

Have you tried to heat it up first? Or use a strap wrench?

Send it to the gun Smith and have it cut off. I did the same thing with a AWC adapter on a factory AI barrel. Remember to use anti sieze in the future.

That would be my last resort if I exhausted all other options. I would put something through the ports to twist it off with some heat before cutting it off.

You could put it muzzle down in a cup of some carbon cleaning solvent for a day or two to see if it lossens up.

APA sells a high heat threadlocker....
(I liked the marketing for the 1st Fat Bastard brake, I just never picked one up. My cheap bastard was stronger than their fat bastard)

Did you install the brake? I would call APA and see if hey have any tips or tricks other than the destructive method.

Heat it up, shove something in the ports that won't mar the metal but will give you some leverage. Wood dowel maybe.

It's likely not seized, but rather being held in place by built up carbon. Agree with the plan B to put it muzzle down in some carbon solvent like Boretech C4 or even some Hoppes.

I busted it lose but now I've got the collar locked up to the break itself... I'm going to try soaking it for a bit. I wish these guys would mill two flat sides on the break itself so I could just use a vice and a wrench in the future. Thanks for you help boys.
