The Sentinel Handguard features an updated design and improved functionality. The Sentinel provides over 40 square inches of protection - a 38% increase over the Star Series guard. The Sentinel is constructed of two different types of plastic - a stiff spine for durability, and a softer body for flexibility. In warmer weather you can snap out the vent cover to increase airflow and cool your hands while maintaining protection. Optional accessories available: LED light kit, mirrors, Hand Wrap and foam extension (Sentinel Armor). Note: Mount kit required and sold separately.
