With rail handguards you really
notice the difference between different quality levels. If there's a part you'll not regret splurging on, it's a quality rail handguard.
For a quad rail I still like the older DD M4 design, the newer Omega X are also nice though. For the low profile block you want a "clamp on" style, not the type with a set screw when used on a barrel that has taper pin scars. Daniel Defense also makes a nice clamp on gas block that's trim enough to fit under virtually any rail.
