So I bought a gun yesterday, had an AAC suppressor QD installed at the gun shop (I bought a Pulsar I/R scope and a bunch of other stuff so they were happy to install for me), of course they installed with the included little tube of Rockset. Got home, excited to try my new NV hunting rig out on the pigs that hit my feeder every night, only to find the QD was not a 51T......probably as much my fault as anyone’s to be honest. My brother in law and I set out to remove (I had another one at the house that I could install), and after about 2hrs of efforts that included heating with a lighter, heating with boiling water, heating cherry red with a pocket rocket camp stove, use of channel lock pliers, vise, etc etc etc, the QD is still on the barrel, the barrel twisted off the action, the barrel is IMO destroyed (we got to a point of not caring any more to be honest, much frustration had set in).


All ideas for removal came off the WWW, and all failed miserably. Any else tried to get one off that had just been installed a couple hours prior and succeeded????

The barrel can easily be re-torqued to spec. But I would take it to a gun smith now to head space it and tighten it back on. No recommendation on brake removal.

band saw? chop saw? hacksaw?

Rockset loosens when you soak in water

Years ago I got a factory AAC upper with one of their suppressor mounts factory installed. Same deal as yours..rock set and it was a bear to remove. I tried almost everything you did including soaking in boiling water, map torch, blowtorch, etc.. The way I finally removed it was by clamping the QD mount in a bench vice and using a pipe wrench on the barrel. I destroyed the mount (use it as a thread protector now) and left wrench marks on the barrel but it still shoots great!

I feel your pain. That rockset is unbelievably hard to break free.


.

So.... was there drinking involved? It really sounds like one of my stories.

Process & patience, Ive never heard of a quick way that works.

Soak in water over night, sometimes takes 24 hours.
With the item still in water bring water to a boil for 10 minutes, turn off heat let sit in water for another 10 minutes.

I would recommend the barrel be placed in a barrel vice to aid in the brake removal. You could do this while at the gun smith.

Reason number 24 to not get a QD suppressor.....

Lol

^^^^^^ this, need to let it soak awhile.

From Rocksett's website:

INCREDIBLE TEMPERATURE RESISTANCE (-350°F) up to 2,015°F
The extreme temperature range makes Rocksett ideal for attaching muzzle devices.
Can only be removed by a hot water soak.
Keeps assemblies from vibrating loose.
Popular for muzzle brakes/recoil compensators and suppressors.

Hey! We will have none of this accurate information nonsense. We need power tools and lots of fire!

the best money spent (barrel vise) some can be tough, but have never failed to get one off

This reminds me of trying to get the smooth barrel nut off of my savage to rebarel it at home. It ended up with two pipe wrenches me on one on the nut and dad on the other on the barrel. The threads were so gunked up with metal shavings etc. when we broke it loose no wonder it was hard to break loose. The barrel now wears some battle marks from the pipe wrench but should be fine to use other than that. The nut is toast!

What I have done for removing rockset muzzle brakes is:
Run a patch drenched in oil through the bore to prevent surface rust(looking at you Savage), place the rifle muzzle down in a soup can or something like that, pour boiling water into the can to cover the brake, let it sit for 15min, dump water and replace with fresh boiling water. I do this a few times and then try to remove the brake. If it doesn't come off I repeat the process until it does.

I’ve also had to get wicked or ugly with a few stubborn brakes - sucks to mar finishes but when Man must prevail - brute force is sometimes necessary .

Also it can be quite humbling at times when little parts take all your strength to come apart - I often think of large suspension bridges and the feats of engineering they represent !
