That's always an option. And I have considered it.

I have a hard time shaving down the FSB though. I could shave it down easy enough, but I just like the old school FSB.

Right now I'm thinking along the lines of a Daniel Defense Omega 9, two-piece floater. I don't mind knocking the pins out of the FSB to install a one-piece floater, but I kind of like the option of occasionally removing the handguard for cleaning, without having to unpin the FSB.

If I could come to terms with shaving the FSB, I could have it all, except the old school FSB. That FSB is part of the signature look of an AR15, and probably the most durable front sight/gas block option.
