The TNVC TNV/PVS-14-NPBM-D is a lightweight, cost-effective non-powered bridge mount designed to convert dual PVS-14 monoculars into a binocular configuration. Based on the TNV/PVS-14-PB—A, the NPBM-D removes the centralized power supply while retaining the stirrup and fastener system of the PBM-A, ensuring secure alignment and lockup of two PVS-14s for improved depth perception, motion parallax, and situational awareness.
Weighing just 2.93 ounces, the NPBM-D is the lightest dovetail bridge mount for PVS-14s on the market. Constructed from durable Delrin polymer and 6061 T6 anodized aluminum, it is compatible with all MIL-SPEC PVS-14, AN/PVS-14, TNV/PVS-14, and NG/PVS-14 systems, requiring no modifications to the host units. Its BNVS-style dovetail interface is compatible with Wilcox and Norotos mounts, providing a stronger, more secure connection than the standard USGI bayonet/J-Arm interface.
The NPBM-D features independently articulating arms, allowing users to adjust interpupillary distance (IPD) and swivel one or both monoculars out of the way for natural vision or compact stowage. Purpose-built for military, law enforcement, and civilian users with existing PVS-14 units, it provides a practical, affordable solution for binocular night vision without costly conversions, while retaining the flexibility to use each device independently. Manufactured in the U.S., it combines lightweight design, durability, and precision engineering for maximum performance in the field.

Important: You must measure the PVS-14 objective lens infinity lock rings to ensure compatibility with the PBM mounting rings. The PBM rings must slip over the infinity lock rings. The inside diameter (I.D.) of the PBM is 1.465″ / 37.211 mm, so the lock rings must be slightly smaller. Use a digital caliper for accurate measurement.
