    I only know of Rocksett mounts coming loose when the barrel and mount were not properly cleaned.

    I watched Surefire's installation video, and yeah, they harped pretty heavily on the cleaning aspect.

    Wow.
    I bought some Rocksett myself just to play with, and there is a 24 hour cure time before the weapon can be fired. I just placed some on a quarter, to see if my lubricant of choice (Froglube) would react badly with it (It dissolves in water, and noone really knows what is in Froglube, so I figured I would see how they got along).

    Anyway, I placed the quarter on the stove burner (I love my cheap apartment) and turned it on "high" to see for myself how it withstood heat. This with about 4-5 hours cure-time. The Rocksett was hard/slick to the touch, and looked clear like a drop of water. After a minute or two, it had turned black and "grown" exponentially, like a hard plastic foam elevated 1/2" off the surface of the quarter.

    They mean what they say when they say not to shoot the weapon for 24 hours! Has anyone ever done this and seen what it looks like on a weapon when instructions are not followed? I was kinda surprised.

    Noveske does use rocksett when installing supressor mounts. I had a similar concern when I bought a 12.5 SS with a 212 flash supressor mounted from them. One thing they didn't use was the thicker "beveled washer"shim that comes with the 212 flash supressor. I guess there barrles don't need it. It makes for a very clean set up. They just used one of the thin indexing shims. I've also got a 10.5 noveske riss ii with 212 surefire can I shoot full auto 50% of the time and no looseness. I installed that flash supressor, rocksett etc. I removed the beveled washer and used only the thin indexing shim. Not loose after 2000rds. and some very hot barrels.

    Firsthand Knowledge

    This has happened to me but it was my fault, Surefire recommends, after it cools to the touch, to dismount and mount the suppressor after firing to prevent carbon from making removal very difficult. Well turns out I waited a bit too long and the flash hider "stuck" to the suppressor, I applied a lot of force and managed to get it off but at the cost of the hider coming with it. Just don't wait too long I guess is the moral of the story. I thoroughly cleaned and reapplied the hider with Rocksett and no problems till this day. Hope this helps.

    Exact specs, Surefire Mini (new lock ring) with 212A flash hider.

    Good Luck

    Who attached your Surefire mount initially?

    How was the mount and barrel cleaned and de-greased, if you were present for the installation?

    Initially my gunsmith, he had seen the Surefire vid and followed it to a tee, he taught me what to do If I ever wanted to attach another hider or brake.

    Yea I was, he used 91% Iso Alcohol and several cleaning patches. It took a good 20 minutes to get all the gunk off. Then when patches came off clean he applied a couple of drops of rocksett on both threads and attached the 212A. (I cleaned the 212A myself with the alcohol for added measure.) Then when I attached I repeated the process only this time I added a lot of rocksett to both the hider and barrel. 728 rounds in and no problems.
