Great FH, I have them on match barrels with no loss. Clean threads and hand tight with just a little wrench.

No washer no worries, it's not going to self tighten enough to cause muzzle distortion, it's also a very good flash suppressor.
If your goal is reduced muzzle flash without a can, Smiths is a solid choice. That said I use A2s.
I have to echo the posts that the Smith Vortex is an effective flash hider. I was involved in testing it when my agency selected it to complement new night vision systems being fielded. I was impressed by it enough that I put one in my luggage to install on my M4 when working as a security contractor in Iraq in '04. At night you generally fire at muzzle flashes and reducing your signature to the level that a Vortex does is a huge tactical advantage. I've gotten older but still have one attached to the 11.5" AR-15 I keep in the house to protect my family.
I am aware of a handful of failures which mostly resulted in one of the 3 flash hider tines breaking off when the carbine / rifle was dropped onto concrete. The A2 flash hider would probably shrug off this type of damage but offers nowhere the degree of flash suppression. So it's your call, but in my mind it's nowhere close to what can be termed a boutique type of upgrade.
It is an exceedingly effective muzzle device. If I already had A2 FS on everything, I might change one or two out for a Vortex. If I had nothing on the barrel yet, I would certainly consider it a worthwhile option if killing flash was on my mind.
