I was watching a vid of the new Colt rifles for 2013 & a lot of their guns have " crown Protectors" as opposed to flash suppressors. I think it's great that companies like Colt & Magpul are already prepared for impending restrictions & are thinking outside the box to get around it best they can. To be honest, I could give a shit about flash suppression. The only reason I want that feature is to protect the crown of my muzzle. Colt has some cool new guns coming out this year. Can't wait!!!
