As you may remember, my barrel is skinny from the FSB to the muzzle, so a crush washer wouldn't look right anyway.
    Don't forget...
    every 0.001" of facing gives you 10 degrees of indexing on 28 pitch threads.

    Thanks everyone for the clarification. Yes I have 3-4 of those washers and I was worried about breaking the threaded portion of the barrel off by torquing too much because it didn't seem as though the crush washer was crushing. I probably got one made out of a titanium, iconnel & diamond.

    I too just stick with the peel washers if I'm doing it myself. I'm OCD with the flats like SuicideHz!

    I'm fixing to duracoat the rifle. Maybe I need to just go ahead and do it so I won't index the Vortex for fear of messing up my duracoat job. Then I won't fix what's not broken. Man, OCD is a bitch.

    AR15barrels,

    I installed the Vortex on my Stag 3L per the instruction. It seems to be seating on the barrel shoulder rather than the muzzle. It looks like there's a few thousandths gap between the muzzle and the inside edge of the Vortex - and when I removed it after the initial hand tightening, the friction marks on the parkerizing on the Vortex showed contact at the shoulder.

    Ever seen this on Stag barrels before? The gap is so small, I don't think it will make a big difference, but I suppose machining off some of the shoulder would make it "right".

    I've also heard that RRA barrels have too long a threaded section and leave a gap between the Vortex and the shoulder despite the skirt on the Vortex.

    The inside diameter of the skirt on the Vortex is around 0.707" to fit on barrels with a diameter of 0.700" behind the muzzle threads.

    I can open up the skirt on the Vortex if required to clear larger diameters.

    The skirt ID is big enough to clear the barrel OD, it's just that the threaded section of the barrel is too short axially, so the Vortex screws all the way down to the shoulder without making solid contact with the muzzle.

    I had trouble with my crush washer not crushing as well, I just put it in the oven to warm it up a bit and this seemed to make it much easier. John
