Just here to second everything Furbyballer said regarding brakes vs. flash hiders.

If you are thinking a SF mini won't suppress well enough for your needs, you want no part of a 6933 fired with a brake on it. It's a lot like firing a 12 ga. in an elevator, just punishing.

I'd run a FH and remember you probably aren't going to put enough rounds through it to wear out any suppressor. SF cans are a long way from the old "mesh and wipes" stuff from 40 years ago.
