The Wilcox L4 G11 Non-Breakaway Mount P/N 28300G11-B, with Horn Interface Shoe allows firm attachment of the AN/PVS-7B/D and AN/PVS-14 J-arm to a variety of combat helmets when attached to a Wilcox One-Hole HMI, Three Hole HMI, or the standard Army Shroud.
The NVG mounting system prevents breakaway of the mount, thereby reducing risk of loss of the NVG.
