Thanks for moving this to the gallery Canjungeo, I posted it in the wrong area. Regarding the Flash hider, Dave at DRC modifies it into a true muzzle brake by welding in an insert in the end of the choate flash hider. Regarding the flash cone, I cannot comment as I hopefully am shooting the gun for the first time tomorrow. I think the 303 jungle carbine used a similiar device to the flash cone, didn't it? I will report range results when I get back.
