I am trying to find the old style vortex flash hider. I have been through about 4 so far and each is not the one I am looking for. The one that I am after has the very end tips sharpened and you could use it as a bayonet. I have seen them but can't find them. If you know who sells this model or have one you want to sell please email me.
A pic of the one I am after is:http://www.gunaccessories.com/MuzzleBrakes/index.asp
Midway down the page. And yes I have tried this company.
