I don't know how much weight you're planning on cutting, but I can't imagine a gas block is going to make or break your build. You definitely don't need to spend a ton to go adjustable:

Most free float handguards use a proprietary barrel nut. You'll want to verify what your handguards uses before you try something different. When shopping for ultralight rail systems, make sure they factor in the nut - some list the rail weight and the nut separately, while others list it all together (or don't list the hardware/nut weight at all).
