Ops-Core Parts & Accessories | An Ecosystem Beyond Armor

Modern tactical environments demand more than just passive armor. Ops-Core leads the industry by offering a modular, mission-adaptable ecosystem of helmets, communication headsets, and integrated accessories built for elite forces and tactical professionals.

The Ops-Core Ecosystem | What Sets It Apart

The true value of an Ops-Core helmet lies not just in the shell itself, but in the highly integrated ecosystem built around it. You must be wondering, what’s so different about it? Let’s talk about the Core features that make Ops-Core the industry benchmark for tactical professionals. 

• Mission-Adaptable: Combat environments change fast. Ops-Core uses tool-free modularity so you can instantly attach respirators or mandibles to your rails on the fly. This scales your protection to the immediate threat without needing a second helmet.
• Complete Integration: Mixing tactical gear often causes painful pressure points. Ops-Core components are engineered to fit together. For example, visors and SOTR masks nest perfectly under night vision goggles and mandibles without restricting your movement.
• Industry Expertise: Acquired by Gentex Corporation, Ops-Core relies on over 130 years of life-support and ballistic experience. This backing drives the continuous research needed to pioneer lighter armor and global standards like the ARC rail.
• Easy Maintenance: Tactical use wears down gear. Ops-Core offers a massive catalog of replacement parts to keep your setup running. You can quickly swap out hygiene kits, foam inserts, microphone wind guards, and battery caps instead of replacing entire headsets.

The Core of the Ecosystem | Helmets

The foundational pillar of this collection is the Ops Core Helmet series, defined by the highly recognizable FAST (Future Assault Shell Technology) geometry.

• Ballistic Options: The FAST SF offers an ultra-lightweight hybrid composite shell, while the FAST XP Gen 2 provides high-threat HG2 protection.
• Bump Helmets: For non-ballistic applications, the Ops-Core bump helmet is constructed from injection-molded glass-filled nylon, providing rigid blunt-impact protection and excellent ventilation.

Auditory Dominance | Communication Headsets

Maintain absolute situational awareness with the Ops-Core AMP (also stylized as the Ops-Core amp) communication headset.

The AMP features proprietary 3D Hear-Through Technology to intuitively pinpoint the spatial origin of ambient sounds. For maximum ergonomic benefit, operators mount these headsets directly to the Ops Core Arc Rail. 

Scale Your Loadout | Parts & Hardware

To maintain, repair, or upgrade your tactical setup, explore our extensive inventory of Ops Core replacement parts and specialized Ops Core Bump Helmet parts. Building out your chassis is easy with these Ops Core helmet accessories:

• Weight Management: The Ops Core counterweight kit perfectly balances the heavy forward leverage of night vision goggles using modular lead weights stored in an elastic pouch.
• Signature Reduction: Attach an Ops Core fast helmet cover to break up the geometric silhouette of your helmet, mitigate infrared signatures, and route NVG power cables safely without snag hazards.
• Facial Protection: Modular STEP-IN visors contour perfectly behind NVGs, while both ballistic and non-ballistic mandibles lock directly onto your rails for advanced facial defense.
• Internal Hardware: Upgrade your stability with replacement LockDown Liner Systems, moisture-wicking pads, and Occ-Dial fit bands.

Headsets & Comms

• AMP Communication Headsets: Available in standard and Near Field Magnetic Induction (NFMI) configurations to block acoustic trauma while providing 3D Hear-Through technology.
• AMP Camo Skin Sets: Adhesive skins available in multiple MultiCam patterns for operational signature management.
• SOTR Microphone: A noise-canceling dynamic microphone that plugs into the SOTR mask, enabling clear radio transmissions without breaking the respiratory seal.

Visors, Mandibles & Respirators

• STEP-IN Visors: NVG-compatible visors that mount directly to the ARC rails via bungees to eliminate ear pressure points.
• Multi-Hit Ballistic Face Shields: Heavy-duty shields that lock into the ARC interface to absorb impacts from 9mm and .44 caliber handguns.
• FAST Ballistic & Force-on-Force Mandibles: Modular lower-jaw protection, including flexible ballistic armor for a natural cheek-weld on a rifle stock, and breathable soft armor for Simunition training.
• SOTR & SOTR Lite Respirators (and Filters): Low-profile masks providing 99.97% particulate filtration efficiency, alongside replacement SOTR filters.

Helmet Hardware & Load Management

• Ops-Core Counterweight Kits: A rear-mounted elastic pouch containing up to 350 grams of adjustable lead weights to perfectly counterbalance the forward leverage of night vision goggles.
• FAST SF Helmet Covers: Mesh and Cordura/Tweave covers that protect the helmet shell, reduce infrared signatures, and use integrated para-cord loops to route NVG power cables.
• Advanced Mounting Hardware: Unity Tactical MARK (Modular Attach Rail Kit) systems and Team Wendy AMP Adapters for specialized headset rail mounting.

Ops-Core | Recommended Tactical Setups

To maximize the effectiveness of your gear, we recommend structuring your loadout based on your specific mission profile. Below is a breakdown of optimized setups built using Ops-Core parts and accessories available through the Atomic Defense catalog.

(Note: While advanced ballistic components are strictly regulated under ITAR and EAR, civilian acquisition is legally permitted within the United States for personal defense and emergency preparedness.)

FAQs | Ops-Core Parts & Accessories

What is the difference between an Ops-Core ballistic and bump helmet? 

A ballistic helmet is designed to catch fragmentation and stop specific firearm projectiles. An Ops-Core bump helmet lacks ballistic composites and is made of nylon to protect against blunt-impact trauma during activities such as fast-roping or search-and-rescue.

Where do I mount an Ops Core counterweight?

 The counterweight kit mounts securely to the extreme rear of the helmet shell. It offsets the heavy forward leverage of night vision devices, reducing neck fatigue.

What accessories do I need for my Ops-Core AMP headset?

To maintain your comms, operators frequently require replacement earseal hygiene kits, foam inserts, microphone wind guards, and battery caps.

How do I adjust the fit of my helmet?

The interior fit is managed using the OCC-Dial, a rotary adjustment band across the circumference of the head.
