FLIR Breach & PVS-14 Q&A

I have gotten a lot of questions about this setup. Here are the ones I get the most and my answers to them. I want to make sure that anybody who is looking at doing this knows what to expect. I especially do not want to give anyone false expectations.

How exactly are you mounting them?

I can only make it work with the KVC, OSS, and K Clips. I get the fusion-like overlay with the Breach on my left eye (weak eye) using the MUM rail with the buttons facing towards the PVS-14, and the K clip that offsets the dovetail to the left of the MUM rail. I’ve tried the other rails with both K clips and the overlay is way off and causes double vision.

Do you get fusion?

Basically, yes! However, sometimes the images overlay perfect and sometimes they do not. It overlays better while stationary. It bounces around when you walk which causes the overlay to shift around but it is more than doable. The main thing is that it’s not 100% consistent which I think it mostly has to do with how fresh or tired my eyes are. When it’s on, it is dead on, and badass. When it’s off, the overlay is slightly off but nowhere near as bad as with the other rails.

Should I get this setup instead of duals?

It depends on what you are doing with it. This setup would work great if you are hunting with a thermal scope. Sitting stationary, the overlay is more reliable, and you have the option to articulate up the NV monocular and scan with thermal only. You will see way more animals scanning with head mounted thermal. IMO, NV duals/binos will be better for running & gunning, dynamic movement, etc.

What works better with it, GP or WP?

Both phosphor colors work very well, however, I find WP is better with outdoor alert mode. The colors go great together, and the NV stands out more which is good for walking/moving.

How do they work in dynamic situations?

Because the overlay is not 100% reliable, I would not count on this set up for serious work like a 2-way range. Also, even with a perfect overlay, it doesn’t work well with quick movements. I find that I need to scan slowly for the overlay to work. Scanning too fast outruns the thermal, meaning you might not get the thermal to “pop” and overlay.

I hope this info helps you out and here's a short video to help show what it looks like. It overlays FAR better than this video. It was difficult to get the videos to overlay as it looks to my eyes. The choppiness is from editing the clips to keep them overlaid as best as possible.
