The Grey Ghost Precision AR-15 Free Float M-LOK Handguard comes with all the features you want while still being minimalist and lightweight. This 12.625” model only weighs 11.2 ounces and utilizes a non-proprietary barrel nut for attaching. Torque the barrel nut to 65 ft/lbs. and then you can slide the handguard on while the anti-rotation tabs ensure it is indexed with the receiver. The free float handguard can then be torqued down to 35 in/lbs. and you have a rock solid set up for mounting any accessory you could need. There are M-LOK slots along the bottom and sides as well as the 1 and 11 o’clock positions at the muzzle end. The full length picatinny top rail is t-marked and sits flush with your M4 flat top upper. Each GGP AR-15 handguard is extruded from 6061-T6 aluminum and hardcoat anodized.

Very nice rail with a couple of misses.

This GGP handguard has a great shape and feel. It is slim with big slots for cooling. The (odd) 12.625" length is perfect for my 12.5" Barrel + Sound Forwarder (KAK Slim Blast Can is perfect). The fitting tabs center it perfectly on a forged mil-spec (BCM in my case) upper.
GGP's great customer service replaced the included barrel nut tool when I broke it (see Cons below).

The barrel nut slots are small and the barrel nut tool slips out easily if you don't press your hand against it to keep the tool tabs engaged.
The included tool also doesn't have a 1/2" torque driver hole so I had to use a lever extension to tighten the barrel nut. That resulted in the tabs on the tool bending & breaking since I couldn't know what torque I hit.
The top picatinny slots have scalloped sides which I believe contribute to a Steiner DBAL-A3 sight not sitting level on the rail when the QR is tightened (it sits perfectly square and level on a BCM MCMR). It gets 4 stars because of this.
