Does it look like its worth using?  
Im going to have a local gunsmith lath and thread my AR barrel, the brake has a blind pin.
Here another question, it has the tottal of 8 vent holes, as you can seen in this picture, how should the holes be lined up? Im thinking, that it should be solid part lined up  with the top & bottom, that way no flash to blind me in low light situations and  for the botton, no dust blowing  back up in the prone position.
 

Comments?

Thats how i would place it.

I'm very new to the AR15 community and am just learning about these guns and things. What I was wondering is if muzzle brakes are legal on post-ban guns. That's a nice looking muzzle brake you have there!
