SureFire HL1 HelmetLight Adapter | ADPT-HL1-OC Ops-Core Mount

Overview of the SureFire HL1 HelmetLight Adapter | ADPT-HL1-OC

A Rotating Mount Built for Ops-Core Rails

The SureFire HL1 HelmetLight Adapter, part number ADPT-HL1-OC, fixes a problem every helmet light owner runs into eventually: the light is only as good as the mount holding it. This tan adapter attaches directly to the ARC side rail of an Ops-Core helmet, or any helmet running the Ops-Core rail system, and locks your HL1 HelmetLight in place with a serrated thumb lever and a steel pivot fastener.

Hands-Free Light, Set to Your Angle

Once the adapter is on the rail, the HL1 rotates a full 180 degrees, so you can drop the beam onto a clipboard, a patient, or a lock cylinder, then swing it forward for movement. Nothing comes off the helmet to make that change.

Patrol officers, tactical team members, and search and rescue volunteers all get the same benefit: both hands stay free. The ADPT-HL1-OC is a durable, battle-proven rotating mount that keeps a proven SureFire light exactly where it belongs.

Key Features

• Purpose-Built Interface: Designed specifically for Ops-Core helmets and helmets using the Ops-Core ARC rail system.
• 180 Degree Rotation: Adjusts the HL1 HelmetLight beam angle to personal preference without dismounting the light.
• Quick Removal: Allows easy removal of the HL1 for servicing, or for transfer to another helmet or a service vest (Z71 mount required, sold separately).
• Positive Locking Lever: A ribbed thumb lever secures the light body and releases it without tools.
• Rugged Construction: Molded polymer body with a steel pivot fastener at the rotation point.
• Tan Finish: Coyote-style tan color that blends with common tan and multicam helmet shells.
• Battle-Proven Design: A durable rotating mount from a brand trusted by military and law enforcement users.
• Guarantee: SureFire backs its products with a 30-day money-back satisfaction guarantee.

Specifications

Compatibility

The ADPT-HL1-OC is made for Ops-Core helmets and for any helmet shell fitted with the Ops-Core ARC rail system. It mounts to the side rail and requires no drilling or shell modification.

This adapter pairs with the SureFire HL1 HelmetLight. It is not a universal mount and is not intended for other flashlight bodies or other rail standards.

Limitations to know before you buy:

• The HL1 HelmetLight is not included.
• Helmets without ARC rails, including many standard PASGT and ACH shells with no rail kit installed, are not compatible.
• Moving the HL1 to a vest or plate carrier requires the separate Z71 mount, which is not part of this package.

Intended Users

Law enforcement patrol and tactical officers use this adapter to run a helmet light during warrant service, building searches, and night callouts where both hands stay on a weapon or a door.

Military personnel and reservists mount it on issued Ops-Core rail helmets so an HL1 can be repositioned between navigation, weapons handling, and close work.

Search and rescue teams, firefighters running rail-equipped helmets, and preppers who train seriously with helmet-mounted lighting also rely on it for steady, hands-free illumination in the dark.

What's Included

• SureFire HL1 HelmetLight (the light this adapter is designed to carry)
• An Ops-Core helmet or a helmet with an installed Ops-Core ARC rail system
• SureFire Z71 mount, if you plan to transfer the HL1 to a service vest
