Ops-Core showed variants of the Future Assault Shell Technology (FAST) bump and ballistic shelled helmets developed to support a recent military solicitation. The FAST helmets use a special variant of the Accessory Rail Connector (ARC) that follows the contour of the ear cut. Additionally, these helmets were dipped in Multicam and include VAS shrouds and Ops-Core’s proprietary Head-Loc chin-strap.
