Ops-Core FAST Carbon Composite Mandible
Elemental and blunt impact lower-face protection for FAST helmets. Carbon composite shell protects against wind-driven debris, rotor wash, and impact hazards in a lightweight, low-profile form factor. This is not a ballistic mandible — it will not stop bullets or fragmentation. For ballistic lower-face protection, see the FAST Ballistic Mandible.

Key Features
-
Elemental & Debris Protection: Shields the lower face from wind-driven debris, rotor wash, branch strikes, and impact hazards. Designed for mobility operations — not ballistic or fragmentation threats.
-
Pivoting Vent Plate: Vent plate pivots open to reduce fogging, enable clear voice communication, and allow hydration without removing the mandible.
-
Mounts Without Using Rail Space: Attaches to the Super High-Cut (SHC) Skeleton ARC Shim — does not occupy the ARC rail dovetail, leaving rails free for lights, lasers, and comms.
-
Scalable: Quickly attach or detach as the mission requires. Pair with a STEP-IN Visor for combined face/eye coverage.
Required Mounting Hardware
Requires a FAST helmet equipped with Super High-Cut (SHC) Skeleton ARC Rails and the SHC ARC Shim. SHC Rails and Shims are available as an upgrade kit for any Ops-Core FAST helmet.
⚠ Not Ballistic. The Carbon Composite Mandible provides elemental and blunt impact protection only — it will not stop bullets or fragmentation. For ballistic lower-face protection, see the Ops-Core FAST Ballistic Mandible.
