The Ops-Core® Force-on-Force Mandible offers full facial protection to all Ops-Core helmets or any helmets equipped with Ops-Core ARC Rails. Designed for use during force-on-force training, the Forceon-Force Mandible provides protection from UTM and Simunition rounds in a low profile, lightweight form factor. While the durable polymer frame provides blunt impact protection, the conforming soft armor allows the user to obtain a solid cheek weld on their rifle, and train as they fight. The Force-on-Force Mandible provides complete neck, side of head and facial coverage when used in conjunction with the Ops-Core Step-In® Visor or APEL goggle alternative. The mandible’s breathable mesh provides natural ventilation while helping to prevent overheating and reduce lens fogging. The Force-on-Force Mandible is one-size-fits-all, fore-aft and vertically adjustable, and easily attaches to any Ops-Core ARC Rail.
