Night Vision Mount Guide (G11,G24,Rhino and Dovetail vs Bayonet)

Published on July 5, 2022
Duration: 13:00

This guide details the complexities of night vision mounting systems, focusing on the interfaces between the NVG device, J-arm, mount, and helmet shroud. It contrasts bayonet and dovetail mounting systems, highlighting the pros and cons of popular mounts like the G11, G24, and Rhino, and discusses the importance of choosing the right J-arm for single-tube devices like the PVS-14.

Quick Summary

Night vision mounting systems consist of the NVG device, an arm (J-arm), a mount, and a helmet shroud. Most helmets use Wilcox shrouds. Bayonet interfaces are cheaper but less stable than robust dovetail interfaces, common on dual-tube systems. Popular mounts include the Rhino, G11, and G24, each with different features and price points.

Frequently Asked Questions

What are the main components of a night vision mounting system?

A typical night vision mounting system involves the night vision device itself, which attaches to an arm (like a J-arm), this arm then connects to a mount, and finally, the mount secures to a shroud integrated into a helmet.

What is the difference between bayonet and dovetail NVG mounting interfaces?

Bayonet interfaces use a plug-in system, often found on cheaper J-arms, which can be less stable. Dovetail interfaces offer a more secure and robust connection, commonly integrated into dual-tube systems and premium mounts like the G24.

Which night vision mounts are most common and what are their pros and cons?

Popular mounts include the Rhino (older, cheaper, can position NVG lower but wears out), G11 (successor to Rhino, more durable, better adjustment), and G24 (premium, push-button, breakaway feature, most expensive). Most helmets use Wilcox shrouds.

Should I tape over the metal contacts on a PVS-14?

Yes, it's often recommended to tape over the metal contacts on a PVS-14. These are designed to shut off the unit when stowed, but they can be inconsistent and randomly engage, potentially damaging the device. Manual shut-off is more reliable.
