Overview

Built for a custom AR-15 setup, this free-float handguard is aimed at shooters who want a lighter, more modular front end without unnecessary bulk. The M-LOK layout supports accessory placement, while the continuous top rail and scalloped rail sections provide a practical interface for optics and other mounted gear. Anti-rotation tabs and the one-piece design are included to help keep the handguard secured on the rifle, and the Gen-2 version adds quick disconnect sling sockets at the 3, 6, and 9 o’clock positions. It also offers clearance for most muzzle devices and 1.5" suppressors, with compatibility for low-profile gas blocks.

Pros

  • M-LOK system provides modular accessory mounting beyond standard 1913 picatinny rails.
  • Built-in anti-rotation tabs help keep the handguard secured in place.

  • Compatible with low-profile gas blocks and includes quick-disconnect sling sockets.

Considerations & Trade-offs

  • The 1.78" inside diameter is intended to fit most muzzle devices and 1.5" suppressors, but fit should still be verified against your specific setup before installation.
  • This is a free-float handguard for a custom AR-15 build, so it is not a universal drop-in part and depends on compatibility with the rest of the rifle components.
  • The continuous top rail and scalloped rail design provide mounting space, but the handguard still relies on M-LOK for most accessory placement rather than full-length rail coverage on all sides.
  • GEN-2 adds quick disconnect sling sockets at the 3, 6, and 9 o'clock positions, which is useful for sling setup but may be more than needed for simpler builds.
