Just run it the way it's set up now--you won't gain anything appreciable over it.
Not true. What you gain with a free float handguard is consistent POI regardless of sling or rest pressure/tension on the forend. People use them for good reason, and it's not just for looks.
What I was really thinking is that if he is going to only run open sights as are shown in his picture, the advantages of a free float are going to be unlikely to emerge in any meaningful way. He needs another AR setup with mid/rifle gas, no sight block, longer free float tube, scope, and nicer trigger to really stack the advantages.
