A little embarrassed to ask this but I just gotta.
I have a RRA m4 that I got from Adco back in March 2003.  It has the "fake" muzzle break on the barrel.  Would it be worth it to send the barrel back to Adco and have a real flash suppressor (or whatever is legal now)?  
What are my options at this pont?  What advantages would I receive?
I saw these
listed on Adco's site.  Is this all that is available?

Any help is appreciated.

Adco also has both phantom and vortex options. i would go with that. Phantom is a FH that works as a brake too. It cuts down on flash at the muzzle and is more fun to shoot at night that way.at the bottom
