Cheaper for a Reason: AGM NVG-40 Night Vision Goggles

Published on March 8, 2022
Duration: 6:14

The AGM NVG-40 is an affordable binocular night vision option but comes with significant drawbacks. It is heavier than comparable models and suffers from optical issues like excessive focus throw and notable lens flare ('hooping'). While it uses surplus Omni IV tubes, the non-milspec glass and smaller eyepieces compromise the field of view and user experience, making it difficult to recommend over a PVS-14 monocular for most users.

Quick Summary

The AGM NVG-40 is heavier (23 oz) and has significant optical drawbacks, including 'hooping' lens flare and smaller eyepieces, compared to competitors. While affordable, its performance issues make it less practical than a PVS-14 monocular for most users.

Frequently Asked Questions

What are the main drawbacks of the AGM NVG-40 night vision goggles?

The AGM NVG-40 is heavier than comparable models like the DTNVG or RNVG. It also suffers from optical issues such as excessive focus throw, smaller eyepieces requiring closer mounting, and significant 'hooping' lens flare from its non-milspec lenses.

How does the AGM NVG-40 compare in weight to other binocular NVGs?

The AGM NVG-40 weighs approximately 23 ounces, making it the heaviest among its direct competitors. For comparison, the DTNVG weighs around 18 oz, while the RNVG and BNVD are both about 20 oz.

What type of intensifier tubes does the AGM NVG-40 typically use?

AGM often uses 'mystery meat' tubes with limited specifications. The reviewed NVG-40 unit contained surplus Omni IV intensifier tubes, which perform adequately for their age but exhibit artifacts like haloing and autogating lines.

Is the AGM NVG-40 recommended over a PVS-14 monocular?

Despite its affordability, the NVG-40's weight and poor optical quality make it difficult to recommend over a high-quality PVS-14 monocular. The PVS-14 is generally considered more practical and offers better performance for most users.
