It its torques down well but the blast is undoing it. What do you all recomme.d? Some suppressor use so there will be me putting torque on them when warm...

I've used red loctite on one and used heat to get it off. If you are using it suppressed you may not want to go that route.

Rocksett works well on my AAC Brake as well.

Cut it out. This is a technical forum. Either post helpful information, or don't post.

The question about silver solder was not what the OP asked about, but it was certainly relevant and I don't think I'd consider it a thread hijack - at least nothing worth editing or locking.

Silver solder is indeed considered "permanent" by the ATF - or at least it was.

Uh..a fal and an ar. Both pws. Brakes. They are attached via screw on threading

Really one will be torques bc of a suppressor. The fal's will not be torqued. Both generate high heat...but that's assumed because it's a gun.

Do you use a screw on suppresser on the surefire ( is it a mount?)

I figured they're screwed on, but how are they retained? Crush washer? Peel washer? Set screw?

The fsc-fal is timed using a crush washer and is torqed on well but the blast has it working loose. The 10.5" noveske is working loose too and it uses peel washers to time correctly. I want them secure. The ar uses a pws fsc. For my yhm can so I don't want it coming off when removing the can either. Surely there is a good way to secure them.

Red loctite. Use a few big drops and even if you just snug it on hand tight it will not budge without a wrench once it cures. It's way better than rocksett garbage.

Are you using enough torque?

Use Rocksett. Red loctite breaks down when heated, Rocksett does not. Rocksett does not have as much strength as red loctite, but strength is not primary consideration in this application.

FWIW, Surefire provides Rocksett with their mounts. AAC recommends Rocksett. I don't know if their mounts actually come with any.

I use peel washers to time my PWS brake and suppressor mounts. I've never had one come loose even at multiple day carbine courses. Are you sure you're torquing them down enough?

I use a Miculek brake on my competition gun, and it installs with a lock nut (who thought that was a good idea anyway?). It comes loose quickly under recoil, so I use a drop of red loctite and apply heat when I need to remove it (which isn't often). I have not had it come loose using the red loctite even under match conditions when it can get pretty hot.

Both have to be timed correctly. In addition they.are pretty snug at the end. Should I use both? I will try and biy some rockset to bad they charge 7 shipping on anitem I could put a stamp on.... seriously on them I can't torque them down more. Keeping them timed is the hard part.

Use red 271 or rocksett. I never had a comp come loose. All my comps need to be timed eith with a peel or crush washer. I use a Nickle based anti-seize on the threads.

Rocksett on my M556 Surfire, Red 271 on my open gun.

You are crushing the crush washer on the gun? fter finger tight you just turn it untill everything lines up. You have 1.5 turns to get it right, do not back off on a crushwasher.

Peel I set the T wrench to 15 ft pounds and go from there. Adjust thickness of the peel washer to time correctly. A 2 step process if you do the math.

They are timed. I just need to know the best threadlocking compound.

Red Locktite (271) deteriorates at temperatures above 400 degrees and will lose it's ability to hold. With repeated shooting, especially under heavy conditions (like say during a carbine class) it will fail. Rocksett does not have the torque holding properties of red Locktite (will break at a couple hundred pounds less), but it's temperature resistance is over 1000 degrees. I would definitely go with the Rocksett. It will hold the muzzle device in place during firing with no problems, will not deteriorate due to heat, and is easily removed should you decide to replace the muzzle device. Lastly, AAC includes a cute tiny bottle of it with their product so the cool factor says you must get it.

ETA - Rocksett must be heated to over 2,000 degrees for it to degrade. Locktite 271 will take up to 500 degrees before it deteriorates. Heavy use of an AR (repeated continuous shooting) will heat the barrel well above 500 degrees. Rocksett breaks free with about 30 lbs of force - but that is more than enough to keep the muzzle device in place during use. The benefit of Rocksett is not its ability to hold at high torque values, but rather to hold even after being subjected to high temperatures - something Locktite 271 just can't do.

Timing is only part of the equation. Proper torque is the other part. Sometimes they can not be torqued down all at once. You get to a certain point, then you back off, then you re tighten. This has to happen until both timing and torque are correct. If you can not do it, I would suggest having a professional do it for you.

Red loctite is a breeze to locate online and at a local store. Outside of the internet, where can you find Rocksett? Kinda funny how people go back and forth on which is better.
