Ops Core AMP Arms: The Definitive Rail Mount with New Vent Mode for Instant Airflow, Situational Awareness, and Free Top Rails

• The Ops-Core AMP Helmet Rail Mount Kit securely attaches your communication headset to the rear of your helmet's ARC Rails. This Berry Compliant system stabilizes your comms and acts as a counterweight to balance night vision devices on the front shroud. It is the standard issue mounting hardware for modern ballistic helmets, designed to keep top rails free for other mission-critical accessories.
• Mount to Rear Rails to Balance Weight: Attaching the headset to the rear of the helmet leaves the top rails open for lights and cameras. This setup shifts the center of gravity backward, effectively counterbalancing heavy night vision optics to reduce neck strain.
• Dump Heat Instantly with Vent Mode: The hinge mechanism creates a physical gap between the earcups and your ears to release heat during heavy physical activity. This lets you cool down immediately without fully removing your helmet or losing comms.
• Lock into Deployed, Vented, and Stowed Positions: The arms snap securely into three distinct modes. Use Deployed for shooting, Vented for cooling, or Stowed for transport. In Stowed mode, the earcups compress against the helmet shell to lower your profile and prevent snagging.
• Maintain a Perfect Seal with 360° Gimbal Action: The attachment point pivots to match the exact angle of your jaw and head shape. This constant pressure blocks dangerous gunshot noise while keeping electronic hear-through audio clear, even while running or moving.

What are some common accessories to add to the Ops-Core AMP Helmet Rail Mount Kit?

The Required Communication Core 

• Ops Core AMP Headset: This Ops Core rail mount kit is the dedicated mounting interface for this specific headset. The AMP mount arm connects directly to the earcups via the gimbal attachment, allowing the system to maintain the acoustic seal and 3D Hear-Through performance required for situational awareness.

The Host Platform (Helmet Compatibility) 

• Ops Core FAST SF Gen 2 Helmet: The Ops-Core AMP arms are designed to mount onto the rear ARC Rails of this high-cut ballistic helmet. This integration shifts the headset's weight backward to counterbalance night vision devices while keeping the top rails clear for lights and strobes.

Visual Signature Management

•  Ops-Core AMP Camo Skin Set: These adhesive covers apply directly to the AMP Headset and Ops Core AMP arms to break up their outline. Use them to match your communication gear to your helmet's camouflage pattern (e.g., Multicam) for a unified, low-visibility profile.

The Ops-Core AMP Helmet Rail Mount Kit with Vent Mode is the only mounting solution that maintains the AMP Headset's full Noise Reduction Rating (NRR) while offering instant heat dissipation.

Ops-Core AMP Vented Rail Mount Kit FAQs

Why should I buy this Ops Core AMP helmet mount instead of just using the headband? 

The headband can be uncomfortable under a helmet. These AMP arms mount the headset to the outside of your helmet. This frees up space inside for comfort and balances the weight of your night vision goggles.

Can I use these arms with my Peltor or Sordin headsets? 

No, not right out of the box. This Ops-Core AMP helmet rail mount adapter kit is designed specifically for the Ops-Core AMP Communication Headset. They connect directly to the AMP's unique mounting point.

Why do I need the "Vented Mode"?

 Helmets trap heat. Vented mode lets you pop the earcups open slightly to create a gap. This dumps hot air instantly so you can cool down without taking off your helmet or losing your radio connection.

What is NFMI and why does it matter?

 NFMI stands for Near Field Magnetic Induction. It is a wireless technology that lets the AMP headset talk to special earplugs. This gives you "double" hearing protection for very loud environments while still letting you hear clear audio.

Why is the "Better Ear Seal" so important? 

If your headset does not seal tight against your head, dangerous noise can leak in. These Opscore AMP arms have a 360-degree gimbal that moves with your jaw. This keeps the earcups pressed firmly against your skin to block gunshot noise and keep your comms clear.

What helmet rails do these fit? 

These fit the standard Ops-Core ARC Rails found on FAST and Sentry helmets. They mount specifically to the rear section of the rail.

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?
