Hey guys, I've a Rem700 that was put together by GA Precision. I've made a deal to sell the gun, but the buyer isn't taking it with the AAC mount. I'm assuming GA Precision installed it using Rocksett, since that is what AAC provides with the mount.
I've read that it's 'water soluable', but I've soaked this thing for nearly two days in my heated, ultrasonic cleaner, and it's still not breaking loose. Since the rifle has been Ceracoated, I don't want to use a real barrel vise on it, as I'm sure it'll hurt the finish, but I do have an internal holding fixture that fits the rails and lugs of the Remington action. But, I don't want to unscrew the barrel before the mount unscrews from the action. To make matters worse, they say to use a ⅞" Open end wrench on it, and it feels a bit big and wants to round off those little corners.
Any other good ideas?

Water is THE way to break down rocksett. Learned this the hard way, completely tore the threads off a S&W MP22 barrel. Heat just makes it more tenacious. Have broken down many since using water soak overnight. Sounds like water is not getting to the stuff because of the cerakote? Unless a customer absolutely insists on using it, because it came with the trick device they want installed, I throw it in the trash. Have taken many a cerakoted barrel off without leaving marks, just use a slip of paper between your bushing and the barrel.

Try to look unimportant. Your enemy might be low on ammo.

GAP may not have used Rocksett. Might be red loctite?? Run it up to 425 and see if it breaks loose. Or better yet, call them first and see what they used. Everything else here is just throwing darts and guessing.
Today, I'm going to try a few different things to see if I can get it broke loose. One will be the boiling water, but I don't actually have much hope for that if my heated ultrasonic cleaner didn't do anything after a couple days. The other will be to hit it with the torch to see if maybe it's actually Loctite.
If that doesn't work, I'll call GAP, as I doubt there is anyone answering the phones on Memorial Day Weekend.
If none of that helps, I've a buddy that runs a local gas supplier, and he says I can come dip it into one of his liquid nitrogen tanks. That might be enought to bust up the ceramic.

You might be better off finding another buyer who will accept the base. I'm afraid the rifle is going to get buggered and the guy will walk. Then you are really stuck with it. A previous poster mentioned that the Cerakote may have been applied after assembly and has sealed access to water. I'm thinking this may be the case. When you call GA Precision ask them what they would charge to remove it. If it is reasonable you will be miles ahead paying them to do it. Don't get impatient. I see buggered guns everyday that people got in a hurry with.

Funny; half my customers have already tried to fix it, with predicable results. I have most of them trained not to F with it; just bring it to me. Not loose in a box.

The AAC mount is for a suppressor. It's not on the action, but threaded to the end of the barrel.
It looks like the mount was screwed on after the barrel was cerakoted. I'd guess the threads are not ceracoted, but left in the white, and then the Rocksett used. If nothing else, I'd expect the water to get in from the muzzle side if it's too close a tolerance on the back side.

Yeah, we also have a group of customers who are students at the "Jim Beam" School of Gunsmithing. One brought in a Winchester pump he had mauled with a hammer trying to get the barrel off. Split the forend in half, bent the barrel ring, dented the barrel, and crushed the threaded end of the mag tube.

When it comes in, in "kit" form", if you train them through their wallet sometimes they get the hint!

How 'bout an update ?

I tried it all. Nothing let loose. When I talked to George at GA Precision, he said that Rocksett, AAC 51T and suppressor shooting often makes them never want to come apart. He told me my best bet is just to cut it off and start over.
While I was hesitant to use the barrel vise and mess up the Cerakote, that's what I've been using (there really is no other good way to hold it when applying that kind of torque). It did not spin, nor leave any marks, so I'm glad.
The flats of teh 51T quick stripped away, so it was time to just muscle it off with a pipe wrench (another piece of advise from George).
Both the internal and external threads are now gone. But it's off. I'll just set it back ¾" and rethread. I'll throw away the left overs of the 51T, or try to turn it into some sort of fun trinket.

WITF do they attach it with that crap? Totally unnecessary. Just use some blue Loctite for crying out loud or machine in a flat and use a set screw. Jeez! Danged if I wouldn't ask them to pay for the cut and re-thread.
