Muzzle Device Tea...

[Shredla]

This is how im spending my afternoon.... a fresh batch of muzzle device tea Because Geissele uses Rocksett on their Super Duty Mod 1 upper receiver groups.

Does anyone have a more practical way?

The huxwrx flash hider is too chunky... needs to go.

Boiling hot water, muzzle device submerged.

take the light off and put it directly on the stove.

FYI I don’t know what I’m talking g about.

 

[sonofeugene]

I think I’d remove the light first.

 

[Shredla]

Light can be submerged to 33 feet, its fine touching the water by a hair

@AR15barrels guru, please advise

This makes me think of the statement "just because you can, doesn't mean you should"

I would think after a couple hot water cycles it should just twist right off there.

Let us know how it goes

Submerged for 2 hours in boiled hot water.. each time the water began to cool i replaced it.
Flashlight is 100% with zero condensation inside, muzzle device still feels as if its welded. Ive given up

Huh, do you have a vice and a tight fitting wrench? (got something to use as a breaker bar..)

Good to hear on the light, I just can't stand submersing anything in water that's not designed to be in there. Just one of my things.

Leave it in overnight and see. Maybe they just put a bunch on there and it just needs to dissolve with time.

Yeah i used vice a wrench a rod that replaces my BCG and fits inside to eliminate any unwanted stress on the upper itself while also keeping the barrel aligned... i tried a regular wrench and then a strap wrench neither budged. Ill just take it to Chosen in chino this week and have them remove it.
The huxwrx flash hider is cool, it works well... but in my current optic configuration (nightforce atacr 1-8) im trying to shave as much weight off as I can. A regular a2 or a spare vltor muzzle device i have will save me a few ounces

 

[22plinker]

Sounds good, let us know what they did to get it off.

Thanks

I saw this on Reddit a while back:

I'm a bit concerned with the amount of people who post photos of destroyed muzzle devices or say you need to boil your barrel to remove rocksett.

Removing a device mounted with rocksett is fairly simple, and involves SCIENCE!

• Wrap your muzzle device in a wet paper towel, and gently squeeze the towel around the muzzle device.
• Then, blow hot air over the muzzle device for a few minutes. Use a blow dryer, or break every firearms rule and exhale all over the tip of that barrel.
• You want water vapor to make its way to your threads. Rocksett breaks down with water, not heat.
• Water vapor can get to places wanter can not as the molecules are smaller.
• Wait an hour or so, still with the towel wrapped around the device
• Wrench it off
• Wipe threads with water, it will dissolve all the leftover rocksett

Wondering what @AR15barrels would do - I'm guessing he has had to do this way more often than most.

 

[Shredla]

100% Randallllllllll probably has it down to a science...

I've used this method on gas block set screws. It worked.

STOP!

Tight muzzle devices are what sometimes causes barrels to unscrew from the barrel extension.
The barrel needs to be clamped directly.
I have made blocks to clamp barrels in the shop press at 20tons or so and they don't move.
Rocksett muzzle devices come off without much trouble once the barrel is properly immobilized.
Make sure you re-oil your barrel TODAY before it starts rusting from the boiling water that stripped all the oil off the barrel that keeps it from rusting.

I have taken off lots of rocksett muzzle devices.
Pure torque is what pops off rocksett the easiest.
All that boiling water and steam ever did in my experience was to make the barrels rust.

 

[Shredla]

@AR15barrels a bench vice and a block like a magpul bev block with a wrench should be good to go as far as pure torque? Or what do you suggest? I reapplied the oil to thebarrel and ran patches already, zero rust.

No.
The BEV block holds the barrel extension instead of the actual barrel.
The barrel extension is threaded on to the barrel and will unscrew if you apply enough torque trying to remove a muzzle device.
Barrel extensions are installed at 100-125ft-lbs so if you exceed that, it's possible to separate the barrel from the extension.

Pull the handguard off the upper and slide the gas block forward and use a pair of blocks with the appropriate sized hole for the gas block seat and put that in a shop press at about 20-25 tons clamping force and then unscrew the muzzle device.
Works every time.

If you don't have all that, come see me.
I have all that.

Ill have to make the pilgrimage out to you, again.
