What I am going to show, and compare, is two different generations of Wilcox Industries mounting solutions for ANVIS (F4949) or PVS-23 (F5050).
The first generation, shown first, is the 41300G02 which replaces the standard ANVIS ball and spring detent with a dovetail type system allowing you to run the ANVIS on a standard dovetail mount like those used to mount PVS-15s. However, the standard aviation mount also includes a way to power the device via the low profile battery pack so Wilcox has created their battery pack system, using CR123 instead of AAs, that mounts to a ratchet style mount with a dovetail style clip.
In theory mounting the ANVIS on a standard dovetail mount seems like a great idea, however in my experience the reality is not so great. The biggest shortcoming is that when you flip the goggles up they are not nearly as low profile as they were with the standard aviation mount, and in addition to this you need a good, solid mount with little to no wobble.
A possible solution to the profile of the goggles might be the Wilcox L4G21M which is the PVS-21 mount however that is $800 alone.
The Wilcox dovetail mount in the pictures immediately below is the L3G10 which is their mount for single hole “Army style” helmets which has an excessive amount of wobble to it – however like with the aviation mount the use of bungees will help mitigate this.
The other large shortcoming of the mount is the weight and bulk of the system. The system has three parts; the battery pack and power pole/strip, the dovetail mount (L3G10 in this case), and the ANVIS mount itself and for the system to work all of the devices must play nicely with eachother. The fact that there is three parts to the system also makes it much heavier than the standard mount.
It should also be noted that this system is NOT compatible with Crye Airframe helmets – the Wilcox power pole is not long enough to go over the hump in the Airframe. Other helmets like the Ops-Core FAST might have a similar problem as well because they go down farther in the neck than the standard MICH helmet.
This system is available from Own The Night.
The newer system, the L4G01 (or G02 for F5050), is much improved over its predecessor. There are no longer three separate pieces to the system, but instead a one piece system that is self powered requiring no need for an external battery pack.
Compared to the previous Wilcox mount, the L4G01 is more similar to the standard aviation mount. It has a similar profile, and the operation is similar however it has a built in removable power supply (utilizing 1x CR123 battery) which can also be swapped out to use a low profile battery pack with the LEMO connector. There is a knob on the battery connector which controls whether the device is powered or not – basically as you turn the knob it either makes a connection with the battery or not, incredibly simple however there is a slightly rattle because of this when the device is not on.
When the goggles are flipped up they are very low profile, much like the standard aviation mount which is great.
Like the previous Wilcox mounting solution this replaces the standard ball and spring detent, however the replacement is very similar except the ball is no longer a ball – it is now more angled to provide positive locking which did not exist with the standard aviation mount.
With the positive locking the goggles will not fall out of your mount like they can on the standard aviation mount, however the ANVIS goggles are surprisingly fragile so there is still some wobble with the goggles – it should be noted that the wobble is on the goggles and tubes themselves, NOT on the Wilcox mount. The use of two small bungees (as pictured) will help mitigate this tremendously.
The L4G01 uses a standard type mount meaning it will mount to an Ops-Core VAS Shroud, Norotos Universal Shroud, a standard USGI mount, or the new Wilcox single hole mount. The mounting system is identical to that of the L4G24 (Wilcox’s dovetail mount that uses a standard mount) and has a ‘breakaway feature’ however the mount seemed to break away from my VAS Shroud even with the feature turned off.
Given the option between the newer L4G01 or the older system there is no question in my mind – the L4G01 is a much better and more improved system, however that comes at a price of around $1425 from TNVC.
Here is a shot of the three different mounting systems. On the far left we have the new Wilcox L4G01, notice how it is far less rounded than the standard aviation ball and spring (middle). On the far right we have the older Wilcox system with the dovetail mount.
