Hi guys, I am a novice when it comes to this kind of stuff. Also doesn't help that I'm an old with memory issues and have currently quit handloading for that reason.
.
I helped my adult son put together an AR type SBR several years ago. We used a drop of blue loctite to put a muzzle brake on his barrel.
I'm pretty sure we can get the current muzzle brake off his barrel. We torqued it to how ever many inch pounds the manufacturer said.
I think we have all the proper tools and equipment needed to take it off.

He has now finally got his suppressor - a cat wb 718 and a muzzle brake type adapter to the supressor called a spooky 2.
He's conviced we need to use rockset to mount the spooky 2 onto the barrel and torque it to i think 30 inch pounds?

Anyway, I was not familiar with rockset till I searched to see how to apply it. According to the manufacturer, apparently we need to use not too much and not to little and let it set for 24 hrs.

Son is dead set on using the rockset and I'm just asking if that is really needed, or would blue loctite be fine to use.

Maybe the heat of the suppressor is over the limit of blue loctite? Thanks for any advice about this, it will surely be appreciated.

Rockset is a permanent bonding. It's fine if you plan to never take it off again.

At the very least I wouldn't use blue loctite because it isn't meant for things that get hot.

Rocksett is my preferred threadlocker for muzzle devices, and I've only had one that I couldn't torque off later without much trouble.

What does the manufacturer say to use?

With the exception of using a crush washer. Red Loctite is the answer for securing a muzzle device that you don't plan to remove. This is especially true of a firearm that may experience a high rate or fire or prolonged course of fire... instances where the barrel is likely to become hot from use. The common culprits being AR15, AR10, etc. Just keep in mind that Red Loctite isn't permanent, it just takes some work and heat the break the seal.

Blue Loctite softens easily with the application of Heat, which makes it easier to remove (heat gun). Blue Loctite is works best for ancillary items such as scope mounts, accessory mounts, and even bolt knobs. It does not hold up to heat from a hot barrel and especially with a suppressor mounted on the barrel (heat sump). I have seen mounts remain attached to the suppressor and simply unscrew when the owner attempted to remove the suppressor after using the rifle. Not the worst thing...

Thanks Chad. Apparently you can soak it in hot water for some period of time and then you can unscrew it. Other wise it seems to definitely be permanent including really extreme temperatures.

Thank you sir. Seems like rockset is by far the best thing to use. try soaking it in hot water if you need to remove the devise.

I personally have used both loctite 241 (red high temp) and rockset either work. The last bit of rockset I used never cured it had plenty of time to set and harden more than 48 hours. You need to have a torch and apply heat to the rockset to cure it properly. To remove rockset you soak it in water for about 24-36 hours.

Loctite you can heat and remove easily. My preference is loctite.

But occasionally I will loosen my asr muzzle brake when trying to remove my can.

Still prefer the loctite

They say to use rockset. I'll post a video in a bit that shows the procedure from the manufacturer that show and exlains the process really clearly.

Thanks for your good info on your experience. Is it possible that your rockset was old? I don't know if it has a shelf life or not.

Thank you for the reply. Blue is definitely off the list now. Rockset or Red loctite is the choice currently. I appreciate your info .

Here is the video

If you use Rockset, boil a pan of water, pour it on a small bean can, stick the muzzle in the boiling water and then just let it sit in the water overnight. It will come right off.

I'm the anti seize guy...rockset and red loctite should be banned for rifle use, in my opinion.

If you must use something, Vibra Tite or a medium grade loctite...everything that is a permanent connection will eventually need taken off and why make things difficult?

Good luck...

Just have to warm it up with torch

I know, it's still overkill unless you're Bobo and can tear up an anvil

I sensed the word "torch".

and the anvil challenge

It came out of a brand new silencer purchase, no identifying marks or expiration dates.
I personally won’t use rockset ever again. Good videos on you tube with silencer syndicate. I highly recommend you watch this videos specifically because the man is a legit good source for nonbiased experience.

My reasons for not using rockset is because I don’t feel water soaking has any place on my firearms.

I use blue Loc-Tite in the "chapstick tube" because I can actually take it apart if I want to later. Liquid red takes quite a bit of effort and I have never considered Rockset because I get the blue for free.
