Ops-Core AMP Arms | Multi-Helmet Mount to Save Important Rail Space
- The Ops Core AMP Helmet Rail Mount Kit aka Ops-Core AMP Arms let you attach your headset directly to your helmet. This frees up room on your helmet for other important gear like lights and cameras. They work with most major helmet brands, including Ops-Core, Team Wendy, and Hard Head Vets.
- Free Up Your Top Rails: These arms mount to the back of your helmet rails, leaving the top open for you to add lights, cameras, or other gear you need.
- Better Balance, Less Strain: By moving weight to the back, the arms help balance your helmet when you use night vision goggles, making it feel more stable.
- A Perfect 360° Seal: The special mount twists in any direction to fit your head perfectly. This keeps the earcups sealed and comfortable, even when you move.
- Low-Profile When Not in Use: The earcups easily swing to the back or side of your helmet when you're not using them, keeping them safely out of the way.

Ops-Core AMP Arms Review
What are some common accessories to add to the Ops-Core AMP Arms?
Helmet Platform Foundation
-
Ops-Core FAST SF Gen 2: This helmet is the foundation of the integrated system. The AMP Arms are specifically designed to mount to its ARC Rails, creating a secure and stable platform for the entire headborne setup.
Primary Audio Integration
-
Ops-Core AMP Communication Headset: The AMP Arms are purpose-built to attach this headset directly to the FAST SF helmet's rail system. This conversion from a headband to a rail-mounted configuration is the core function of the arms, providing superior stability and a streamlined profile.
Accessory Mounting & Rail Optimization
-
Princeton Tec Switch Railink: By mounting the AMP headset to the rear, the AMP Arms leave the top portion of the helmet rails free. This provides an optimal, unobstructed position for mounting compact illumination tools like the Switch Railink, which is designed to fit all Ops-Core FAST helmets.
Mission-Specific Protection
- Ops-Core SOTR (Special Operations Tactical Respirator): This respirator integrates with the overall helmet system for protection in harsh environments. The AMP Headset features a dedicated accessory port compatible with mask microphones, ensuring clear communication is maintained while wearing respiratory protection.
- Ops-Core Step-In Visor: As a key component of the fully integrated Ops-Core headborne system, this visor provides seamless eye protection that works in concert with the FAST SF helmet and the rail-mounted AMP headset.
Cross-Platform Integration
-
Team Wendy AMP Adapter: This adapter enhances the system's versatility by allowing the Ops-Core AMP Arms to be mounted onto Team Wendy EXFIL® rail systems. This allows operators to integrate the advanced functionality of the Ops-Core AMP headset and arms with Team Wendy helmet platforms.

Ops Core AMP Rail Mount Kit FAQs
Will these arms fit my helmet?
These arms are made to fit the most popular tactical helmets. They work with Ops-Core ARC rails, Team Wendy EXFIL rails, and Hard Head Vets M-LOK rails.
Why should I mount my headset to my helmet?
Mounting your headset with these arms frees up space on your helmet's side rails for other gear, like lights or cameras. It also helps balance your helmet, which makes it more comfortable when you use gear on the front like night vision devices.
How do the earcups stay sealed on my ears?
The arms attach to the earcups with a special joint that allows for a full 360-degree adjustment. This helps the earcup fit perfectly against your head and moves with you to keep the seal tight.
Can I move the earcups out of the way without taking my helmet off?
Yes. The earcups can be rotated to the side or to the back of the helmet when you are not using them. This keeps them tucked away in a low-profile spot.
