Overview

Designed for a custom AR15 build, this free-float handguard focuses on a streamlined profile while preserving a solid, stable mounting platform. Its M-LOK layout supports modular accessory placement, and the continuous top rail gives you a consistent surface for optics or other rail-mounted components. Built-in anti-rotation tabs and a one-piece design add practical security for setup and use, while the GEN-2 quick disconnect sling sockets at the 3, 6, and 9 o’clock positions expand carry options. It is also compatible with low profile gas blocks and is intended for builds where reduced bulk and a clean handguard profile matter.

  • M-LOK system adds modular accessory mounting options.
  • Machined to mil-spec dimensions for a precise fit.

Considerations & Trade-offs

  • The 12.7" length is a fit-specific choice, so it should be matched carefully to the intended AR-15 build and gas system layout.
  • The 1.78" inside diameter is stated to fit most muzzle devices and 1.5" suppressors, but larger accessories may not clear without checking dimensions first.
  • M-LOK modularity and the continuous top rail offer flexibility, but they also mean accessory placement should be planned around the rail layout and available mounting points.
  • Built-in QD sling sockets at the 3, 6, and 9 o'clock positions add convenience, though some users may still prefer separate sling hardware depending on setup.
