Overview

Built for AR-15 owners who want a streamlined handguard setup, this free-float option is designed to support accuracy potential while leaving room for modular accessory placement. The integrated Picatinny top rail and KeyMod slots at the 3, 6, and 9 o’clock positions give you flexibility for adding rail segments and accessories without committing to a full-length rail system. It fits a standard AR-15 upper receiver and uses machined aluminum construction with a non-reflective hardcoat anodized finish for a restrained, field-ready look. A proprietary barrel nut and mounting hardware are included, along with one KeyMod rail segment; additional segments are sold separately.

Considerations & Trade-offs

  • The 8" length is specific to compatible AR-15 setups, so fitment should be confirmed against the intended upper receiver and build configuration.
  • KeyMod accessory mounting is supported, but only one KeyMod rail segment is included; additional rail segments are sold separately.
  • The handguard includes a built-in Picatinny top rail, but accessory placement on the sides and bottom depends on the KeyMod slots and any added rail segments.
  • Its 1.5" outside diameter and 1.3" inside diameter may affect how much clearance is available for the user's preferred grip or accessory layout.
