Have you thought about building or contracting to have built a false flash suppressor(ffs)? Especially one with set screws like your set screw compensator. There are many people, myself included, who want to have "the look" without the noise that accompanies a compensator/muzzle break. I hope and many believe that the AWB will sunset next year and don't want to (semi-)permanently affix a fake flash hider to a barrel only to have to heat, beat and /or cut it off in a year. I believe such an FFS would bring many sales, plus I personally would like one. Thanks.
