SureFire HL1 HelmetLight Adapter Features The SureFire HL1 HelmetLight Adapter attaches directly to Ops Core ARC rails for a secure battle-proven mounting interface that increases the utility and versatility of compatible Ops Core helmets by adding SureFire HL1 HelmetLight hands-free illumination capability. The rotating mount provides 180 degrees of light angle adjustment for personal preference allowing the operator to position the HL1 beam for close-range task lighting forward illumination or any angle in between without removing the adapter from the helmet. A tool-free removal design allows the HL1 to be quickly detached from the adapter for servicing battery changes or transfer to other helmets and service vests when paired with a Z71 mount. The Ops Core helmet light adapter is purpose-built for operators running Ops Core helmets or compatible ARC rail systems who want to integrate the SureFire HL1 HelmetLight into their existing helmet platform without modification. The battle-proven rotating mount construction delivers the durability demanded by military and law enforcement operators in sustained operational use. A Z71 mount is required separately for transfer to service vests and non-ARC rail helmet platforms.
