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, anti-rotation tabs, and mil-spec dimensions are intended to support a secure fit while keeping the profile clean. The scalloped rail sections help reduce unnecessary bulk, and the 15-inch length suits longer handguard configurations. Note that the barrel nut is not included and must be purchased separately.

Pros

  • Lightweight free-float design suits custom M5 .308 builds without added bulk.
  • M-LOK system provides modular accessory mounting beyond standard 1913 Picatinny rails.
  • Built-in anti-rotation tabs help keep the handguard secured in place.
  • Machined to mil-spec dimensions for a precise fit on compatible builds.
  • 6061-T6 aluminum construction offers a strong, purpose-built handguard platform.
  • Available in 15-inch length with black or flat dark earth cerakote options.

Considerations & Trade-offs

  • Barrel nut is not included, so the handguard cannot be installed as a complete setup without the separately purchased barrel nut (SKU 100-035-811).
  • The 15" length is specific to this configuration, so fitment depends on the intended M5 .308 build and rail coverage needs.
  • M-LOK modularity offers flexibility, but it may require matching accessories rather than a full-length Picatinny setup.
  • The 1.72" inside diameter is a fixed dimension, so compatibility should be checked against the barrel and any planned front-end components.
