Overview

Built for a custom M5 .308 setup, this free-float handguard is aimed at shooters who want a streamlined front end with M-LOK modularity. Its one-piece design includes built-in anti-rotation tabs and scalloped rails, helping keep the profile clean while maintaining a secure fit on the rifle. The 15-inch length and flat dark earth cerakote finish make it a practical choice for a build where accessory mounting and a consistent look both matter. Note that the barrel nut is not included and must be purchased separately.

Considerations & Trade-offs

  • Barrel nut is not included and must be purchased separately, so this handguard is not a complete install kit on its own.
  • The 15" length is suited to a specific M5 .308 build setup, so fit and balance depend on the rest of the rifle configuration.
  • M-LOK modularity offers attachment flexibility, but it does not provide a full-length 1913 Picatinny rail surface.
  • The 1.72" inside diameter may affect compatibility with certain barrel or accessory setups, so dimensions should be checked against the build plan.

Suggested Comparisons
