Which Handguard / Rail for 300 Fireball SBR?

[azsugarbear]

I'm in the process of putting together a 300 in an AR15 platform. It will be an SBR with a 10.5" barrel. The gas block will be an adjustable .75 from tp555 in the pistol position. I want something relatively inexpensive (Daniel Defense is nice - but out for now). Something that will come just in front of the gas block, but still allow me access to it from the side. Any ideas? I know there are at least a few of you who have already encountered and solved this problem to your satisfaction.
