Overview

Built for a custom M5 .308 setup, this handguard is aimed at hunters and shooters who want a streamlined free-float front end with M-LOK modularity. Its one-piece design, anti-rotation tabs, and mil-spec dimensions are intended to support a solid, low-bulk build without adding unnecessary weight. The scalloped rail profile and 1.72" inside diameter give it a purpose-built fit for compatible configurations, while the barrel nut must be purchased separately. Available in 15" lengths and in black or flat dark earth cerakote, it offers a clean option for tailoring a rifle to field or range use.

Considerations & Trade-offs

  • Barrel nut is not included, so this handguard requires a separate purchase before installation.
  • The 16.6" length is specific to this configuration, so fitment should be checked against the intended M5 .308 build.
  • The 1.72" inside diameter may limit compatibility with larger barrel or accessory setups.
  • M-LOK modularity reduces bulk, but it also means accessories must be selected to match the M-LOK interface.
