AR15 Handguard 7" M-LOK — ONYX Line

Introducing the Outerwild ONYX Line

Machined in-house from our custom 6061-T6 Aluminum extrusion, the ONYX Line from Outerwild delivers mission-critical strength and stability with a deep, lustrous black hard-coat anodized finish. Featuring full-length 1913 Picatinny Rail along the top and M-LOK mounting points along 3 o’clock, 6 o’clock, and 9 o’clock positions. The robust ONYX Line of handguards provides the modularity to accommodate the most popular setups and endless customizability.

Unlike many manufacturers who simply cut holes and slots in their extrusion, we machine every surface of the exterior to ensure a uniform and flat surface and tumble them smooth. Our 4140 steel barrel nut does not need to be indexed for gas tube clearance, and easily installs with a standard castle nut wrench.
