I did do a search on this on the forums and no relevant results. You've probably seen these out there - basically a shroud around a muzzle brake, that is meant to redirect the sound forward. Seems redundant to me. First, the muzzle brake portion of it would not be a brake anymore since the gasses would be directed forward along with the sound, making it no better than a barrel without the brake? Second, how is the sound with these any different than a plain muzzle on a barrel?? I am all for reducing the sound bak towards the shooter and to the sides, but I don't see this as any different from a plain muzzle on a barrel - possible worse with regards to flash from what I have seen. Seems to be a gimmick that everybody and their dogs are now making. Thoughts??
