Overview

Built for a custom AR-15 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 continuous top rail support a clean, stable platform without unnecessary bulk. The handguard is compatible with low profile gas blocks and offers space for most muzzle devices and 1.5" suppressors, making it a practical choice for rifles set up for hunting, range use, or general field carry. Gen-2 additions include quick disconnect sling sockets at the 3, 6, and 9 o'clock positions for more flexible sling placement.

Considerations & Trade-offs

  • The 16.6" handguard length is a fitment-specific choice, so it may not suit shorter or more compact AR-15 configurations.
  • Its 1.78" inside diameter is designed to fit most muzzle devices and 1.5" suppressors, but larger accessories may not clear.
  • The continuous top rail and scalloped rail design provide flexibility, but the handguard still relies on the M-LOK system for most accessory mounting.
  • Compatibility is listed for low profile gas blocks, so builds using other gas block profiles may require a different setup.
