Outerwild Outpost AR-10 18″ Premium M-LOK Handguard – Black Anodized
The Outerwild Outpost AR-10 18″ Premium M-LOK Handguard is engineered from a custom 6061-T6 aluminum extrusion and fully machined in-house for superior consistency and precision. Unlike many manufacturers that merely cut holes into their extrusions, we machine every external surface to create a flat, uniform finish you can feel.
This extended-length handguard features an included 4140 steel barrel nut with a hard coat anodized finish. The barrel nut requires no indexing for gas tube clearance and installs effortlessly using a standard castle nut wrench. Built-in anti-rotation tabs maintain proper alignment under recoil, while the handguard’s inside diameter of 1.250″ accommodates most low-profile gas blocks.
