    Another potentially dumb question about Rocksett...

    My precision-oriented AR has a Smith Vortex FH on it. I've got a new, unopened AAC Blackout lying around here that I'd like to put on the upper (Noveske).

    My reservation is that the Blackout requires Rocksett, while the Smith Vortex does not (it self-tightens during shooting due to the way the tines curve). While I doubt I'll ever remove the Blackout once installed, if I ever did, the old Rocksett would be gunked to the threads and virtually irremovable (or so I've been told). I'm a KISS kind of guy and I don't like doing things that only go one way.

    The other thing is that, should I ever want to remove the FH for a deep cleaning, the Rocksett might make that impractical. I've also heard that Rocksett can help trap carbon in the threading and promote pitting.

    All of that said, is there any merit to wanting to stay away from it? Just to clarify, this is the NON-silencer Blackout - it's just a straight FH.

    Thanks in advance and thanks for putting up with my overly-analytical OCD yet again.

    You only need the Rocksett for securing it when using a suppressor. Just install it with a peel or crush washer and don't worry about it.

    Don't use a crush washer on the blackouts, rocksett is not the boogey man and more times than not can easily be loosened with a lil elbow grease.

    Ok, here's another question then: is anything (i.e. Rocksett, washers) even required if I'm not going to use it as a suppressor mount? If it doesn't require a crush or peel washer with Rocksett, would it require them without it, provided it was torqued correctly?

    Don't worry about it. Put a SINGLE drop of Rocksett on the threads and torque it on. You WILL be able to break it if you need to at a later date.

    What are my chances of getting one off if I used 3-4 drops like the instructions say? I have one that I installed by the directions before doing a little homework here. I Should have known better. Now I'm worried about screwing up my upper or the barrel threads trying to remove it.

    I went through this a few months ago. My flash hider was extremely difficult to remove. With the barrel in a barrel vise it took a good hammer blow to the wrench to break the Rocksett and continued to take a considerable amount of torque to unscrew it. I thought I'd screwed up the threads but they looked OK under a magnifying glass. Had to chase them with a tap and die, though, to clean them up.

    If you cannot remove it with a proper wrench and elbow grease, you can always try soaking muzzle down the muzzle device in water for 24hrs. and should significantly break down the bond of the Rocksett.

    This is what I want to avoid. Now I know Rocksett can be used safely, but I'd rather avoid it. So... is there anything wrong with simply torquing it on without a washer or Rocksett?

    Yes, it will come loose surprisingly fast.
