MRW, you were asking about flash hiders, not muzzle brakes,,, right?
No.
I've paid the terrorist prices for prebans over, and over, I refuse to do it anymore (Of course I've said that for the last 6 prebans), they're just not worth it [u]IMO[/u].
I know what it feels like to pay $1,300.00 for a preban - we NEED to believe they're worth more, and they ARE - about $4.00 more.
I used to pay extra for a good crown, & no lug on an H-Bar in the 80's (I know I'm not the only one). That used to make sense once - when we could be "trusted" with such things (A GA woman actually was killed with a mounted bayonet by her husband - the town sheriff,,, in 1953!).
If you just want a flash hider (I hate to post this on a public forum), Wilson's "Tactical Brake" is the best "brake" I've ever tried. It's not really the best break, but it's a surprisingly effective flash hider. I don't know how in the hell the BATF approved that thing (but get one before it gets revaluated).

One of the quietest real brake I've tried is made by DPMS - not the best, just one of the quietest (The expensive one with all the goofy annular holes from Brownells is supposed to be the best).

If you're only asking if it's really WORTH IT - there's no answer. Not until we get rid of this ridiculous "law."
