I am trying to find option that amounts more to muzzle protection then muzzle break for my post-ban upper.  The turn around time for my other post-ban upper has been very substantial and not to my liking.  The setscrew style of attachment does not really float my boat either.  I did consider the Bushy Mini-Y because of attachment method, overall quality of work and speedy turn around time of Bushmaster but everyone tells me it is terribly loud.  What manufacturers style and installation meet your particular needs?  

Here's some [url=groups.msn.com/TheMarylandAR15ShootersSite/muzzledevices.msnw]muzzle devices[/url], both pre- and post- ban, and some muzzle [u]brakes[/u]
