To lube or not to lube

[NCHillbilly]

So, I've searched and have not found a definitive answer. I have a dead air sandman that I use on numerous weapons. I have qd brakes on said rifles.

After extended sessions on ANY of the rifles, the suppressor almost seems welded on. Question 1: what cleaning/maintenance do I need to do to the can? Question 2: Should I lube the ratcheting portion of the can, and if so, what product should I use?

Put just a small dab Never Seize on it. By end of the shootin session it will be all over you, but suppressor will screw off

My issue is that because I use qd brake mounts, there are no visible threads. It has an internal ratchet that you twist to tighten the can to the brake. I could put some lube down into the ratcheting mechanism, but not sure what to use due to the high temps.

Call the manufacturer of the can and ask them about cleaning. Doing the wrong method of cleaning may void your warranty. I would ask about the QD also.

Yeah, I looked that up last night after I posted. Didn't say anything about lube, but I swear, I didn't think I was going to be able to remove that thing yesterday. I guess it must have just been heat expansion, but it was many hours after I finished shooting before it would come off. And just fyi, I was not doing mag dumps, but probably fired 75 rds over the course of 1.5 hours.

For me, when I rotate into position and tighten the ratchet, it's tight but not "wrenched" on tight via grip. Of course everyone's grip is different but a "normal" adult male strength. A sheen of a decent oil will help keep the carbon lock at bay to where it helps with unlocking. Shoulder and splines.

that was alwways a huge problem for my old AAC cans.

i stopped taking them off and on and turned 2 of them into direct thread mounts by putting set screws into the side where the flash hider teeth are. there’s still enough room to get a wrench on the flats. aac has shitty mounts

maybe try some copper anti-seize. works good on car parts.

I have one Deadair Sandman that I switch between rifles and deal with the same thing as you. I have started putting the tiniest amount of CLP on the muzzle device where the can keys on and it seems to solve the issue.

I have a sandman S. AR and bolt gun. Break it free after shooting, when it’s barely cool enough to touch. When I clean the rifle, it gets a couple drops of oil on the ratchet ring. That’s it.

I replace the ratchet ring every couple years.
