Our take on the Cold Harbour Ruggedized Aluminum J-Arm (RAJ)

The Cold Harbour RAJ is a full-aluminum J-arm that mounts a PVS-14 or similar monocular night vision device to a dovetail helmet mount. It is machined from 6061T6 aluminum in Canada and Cerakoted, with arm geometry shaped around Cadex and Wilcox mounts so the device stows close to the helmet. Unlike button-and-hinge articulating arms, it swings on a precision shaft, letting the user move the PVS-14 from one eye to the other or out of view without mechanisms that wear out. It suits night vision users who want a light, simple, rugged mount and prefer a set-and-forget swing tension over push-button articulation.

About the Cold Harbour Ruggedized Aluminum J-Arm (RAJ)

The Cold Harbour Ruggedized Aluminum J-Arm (RAJ) is a full-aluminum dovetail mount for a PVS-14 or other monocular night vision device. It is made in Canada by Volk CNC Machine from 6061T6 aluminum and is Cerakoted.

The arm geometry is built around the Cadex and Wilcox NVG mounts, so the PVS-14 stows close to the helmet. The device can swing out of view, and it can move from one eye to the other without buttons or other mechanisms. The arm turns on a precision-machined shaft. Swing tension is pre-set and can be loosened or tightened. Steel washers on each side of the arm protect the finish and hold the friction setting.

A retention loop at the rear of the dovetail keeps an elastic retention tether from pulling the device out of alignment. It also pulls the device back into the dovetail if the dovetail release button is pressed by accident. The mounting point is doglegged back 0.3" to bring the PVS-14 closer to the face, which gives a wider field of view. Lightening cuts reduce weight, which leaves room on the helmet for other equipment such as thermal clip-on devices or mission recorders.

Questions and answers

Does the RAJ fit a PVS-14?
Yes. It is built for the PVS-14 and similar monocular night vision devices with a dovetail interface.
Which helmet mounts does it work with?
It is designed around Cadex low-profile flip-up mounts and Wilcox NVG mounts. It uses a dovetail shoe, not a bayonet.
Can I adjust how stiff the swing is?
Yes. Swing tension is pre-set but can be loosened or tightened by the user. Steel washers on each side of the arm hold the friction setting and protect the finish.
How is it different from an articulating J-arm?
It has no buttons or hinge mechanisms. The arm swings on a machined shaft, so you can move the PVS-14 out of view or to the other eye by hand.
What is the retention loop for?
It gives an elastic tether a rear attachment point on the dovetail so the tether does not pull the device off alignment.
What is it made of?
6061T6 aluminum with a Cerakote finish, machined in Canada.
