The FMA GSGM (Ground Spec Goggle Mount) accommodates the L-3 GPNVG-18, L-3 FGS-PI, and ITT AN/PVS-23 (F5050).
Dummy AN/AVS10 NVG compatible.
This mount interfaces with a helmet as a single assembly and is not meant to be quickly taken apart in the field.
Vertical adjustment is achieved via throw-lever and provides significant travel.
The goggle attaches to the mount via its ball-detent ANVIS-style interface and stowage is allowed by activating the side button.
The GSGM features a permanently attached LEMO Cable Adapter that connects with the remote battery pack that comes with the goggle.
A Master Power Selector Switch is located on the right side of the mount, giving users the ability to toggle between remote or internal battery at the flick of a switch.
This switch is protected by a sliding lock to minimize the chance of accidental activation.
Takes x1 CR123A Battery.
Black in colour.
This kit includes three types of mounting adapters:
TB1301-A FMA GSGM Mount Interface Plate For 3 Hole Mount: This adapter allows the GSGM mount to be installed on commonly used ACH specification night vision goggle bases, or to mount ANVS interface night vision goggles onto BNVS specification mounts in a different form.
TB1301-B FMA GSGM Mount Interface Plate For 4 Hole Helmet: This adapter allows the GSGM mount to be installed on four-hole helmets, which is the most commonly used method by special ground units like CAG. It has the same specifications as the AVS-9 night vision goggle mount, so it can be directly replaced.
TB1301-C FMA GSGM Mount Interface Plate For 56P Helmet: This mount allows the GSGM to be installed on commonly used 56P helmets. The curvature of the backplate is designed to fit the 56P helmet.
