Sgt Of Arms AR15 ARCA Handguard 17.5″

This is one of the most versatile handguards on the market.  It has full M-Lok capabilities on the sides and bottom, but also has a full ARCA Swiss rail built into the bottom.  The ARCA rail is great for locking into a tripod or for moving your bipod, or other accessories, to any point on the handguard without having to add picatinny sections to the handguard.

These are compatible with the Aero Precision M4E1 upper receivers or the bar barrel nuts.  If you do not already have either of these, then you will need to add a barrel nut in the above options to fit onto your existing upper receiver.
