You are going to have to take the gas block off to install a cheap free float. Yankee hill makes some inexpensive rails, kinda heavy. Model1 sales make some cheap handguards.
you can put a carbine length handguard on without replacing the gas block, if you want anything longer, you will need a low profile gas block. Yankee hill make a cheap one.
Or you can go with a 2 piece free float like a Midwest industries
