The AGM Dovetail Helmet Mount (Part #6103HS51C) attaches night vision goggles to helmets equipped with a shroud, using a universal dovetail interface that works across shroud types without requiring a proprietary adapter. Machined from aerospace aluminium and weighing just 120 g (4.2 oz), the mount delivers 130° flip-up travel, 1.5 in (39 mm) of eye relief adjustment, 0–21° goggles tilt, and 1.2 in (30 mm) of vertical position adjustment — all operable one-handed. The dovetail interface requires a compatible adapter shoe; confirm your NVG's interface type before ordering.

Who this is for

• NVG operators running shroud-compatible helmets: the universal shroud attachment eliminates the need for platform-specific hardware across ACH, FAST, and MICH-style cuts
• Users who need precise NVG positioning: independent adjustment of eye relief, tilt, and vertical height lets each shooter dial in optic placement without compromising head balance
• Anyone prioritizing low-profile carry: the all-metal bracket sits close to the helmet shell in the flipped-up position, reducing snag points during movement

Compatibility with parent armor

The AGM Dovetail Helmet Mount attaches to any helmet fitted with a standard NVG shroud. Because the dovetail interface is not shroud-specific, it functions across a broad range of platforms without modification. The mount also supports the Flip-Up Shut-Off System when paired with specific interface shoes — confirm shoe compatibility with your NVG unit before installation. The dovetail adapter is not included; purchase the correct adapter for your night vision device separately.

Function

Once seated, the mount locks firmly into both the operational (down) and stowed (flipped-up) positions, preventing unintended movement during activity. The safe-disconnect feature lets the user configure the mount either for a secure lock to the shroud or for a controlled break-away under stress, reducing injury risk if the assembly catches on an obstacle. One-handed mechanical operation covers all adjustments: flip-up, eye relief, tilt, and vertical height. The automatic switch-on/off system activates or deactivates the attached NVG as the mount flips down or up.

Specifications

Frequently asked questions

What helmets does this mount work with?

It works with any helmet that has a standard NVG shroud. The dovetail interface is not shroud-specific, so it fits ACH, FAST, MICH, and other shroud-equipped platforms without modification. The helmet itself must have a shroud already installed — this mount does not attach to bare rails or unmodified shells.

Does this mount work with any NVG?

It depends on the NVG's interface type. The mount uses a dovetail interface, so the attached night vision device must have — or be fitted with — a compatible dovetail adapter shoe. AGM's own NVG-40 and NVG-50 series are confirmed optional pairings. Confirm your NVG's interface before purchasing, and order the appropriate adapter separately.

Is the adapter shoe included?

No. The dovetail adapter is sold separately. When ordering, ensure your NVG is compatible with the dovetail interface or that a suitable adapter is available for your specific device.

What does the safe-disconnect feature do?

The safe-disconnect feature gives two operating modes: a secure-lock mode that holds the mount firmly to the shroud under normal use, and a break-away mode that allows the mount to release under stress — for example, if the assembly snags during movement — to prevent neck or head injury. The user selects the mode during setup.

Does the automatic switch-on/off system work with all NVGs?

It depends on the interface shoe. The automatic power switching function — which turns the NVG on when flipped down and off when flipped up — is compatible with specific interface shoes only. Verify shoe compatibility with your NVG model before relying on this feature.
