They work awesome. I started with a SF brake, but they tend to jam up the ratchet system after 600+ rounds. It's also hard to get the can on/off. The brake has a slot, the hider actually has a cutout. Can't have that. The SF flash hiders are the way to go. the pic is of my mini, honestly, the 556k is the way to go and a little quieter. The mini takes the "ringing" away. I have a 556k pending with the batf.
