SKU: SO1-ECOTI-MNT-1531

Unfortunately, no detailed photo of the 1531 Bracket and exact measurements of the diameter in mm are listed, how it mounts and where exactly?


Does anyone have the current ECOTI Mount Bracket from TNVC for the L3 1531, can you please post some photos of the bracket, how it looks mounted and if and are you satisfied with it?

Can you measure the Bracket, how many mm is it? Is the Bracket diameter 148mm to fit the 1531?


Where exactly does the Mount Bracket fit to the 1531?

1. Is it on the raised lip portion?

2. Or behind it, where the housing is lower and has some raised slots? Does the Mount Bracket have slots/grooves to connect into this area of the housing?

3. Or both areas (raised lip and behind it) so it locks in?

Is the mount longer horizontally to pass over the hump of the lip, so it reaches the front of the 1531 lens to project the image?


How secure is the Bracket Ring to BNVD, are the undersides of Bracket ring clamp coated with rubber, etc., what features does it have to prevent slippage, shifting, vibrations and movement during use and if the thermal gets bumped?

What fail safes are built in the Mount Bracket to prevent marring and wearing the finish, damaging and cracking the 1531, since the housing is resin plastic, and the Mount Bracket is metal? Overtightening screw could crack housing and tube, without knowing torq size and lbs setting, tools needed, etc.


It's now December 2022 so I hope that Bracket is better than what's pictured the others were using in the old SN thread linked below. MODS if I can't link this website, please remove my post, I'll repost without link to photos, etc.

I don't want to mount the Bracket to the focus ring of the 1531, so I hope the current design has improved. I'm also looking for some detailed feedback from users who actually have one on their 1531 and if it is GTG 100%?

Will has a good video linked below, but doesn't show the current Bracket sold at TNVC

Thank you

Optics1 made a bracket specifically for the BNVD-1531 after that video was made of course (thanks for watching )

The bracket mounts to the body (the big raised portion behind the objective lens). I don't have one to measure but no need because it is designed exactly for it. See below.

And to answer this question:

What fail safes are built in the Mount Bracket to prevent marring and wearing the finish, damaging and cracking the 1531, since the housing is resin plastic, and the Mount Bracket is metal?

The bracket cannot be made so tight that it would damage the housing.

Sorry to bother you, the reason I asked for the specific diameter of the ring in mm , was to see if we can also use it for other devices as well, as a poor mans multipurpose mount, if it's not specifically molded to lock into the 1531 lip

If it's just a bigger 31 mount ring, then we'll understand

Thank you Sir Will for your time and the information!

@ar15city
ETA: The OD of the 1531 body where it mounts to will be the ID of the ring. The clasp allows you to tighten it as needed for a secure attachment. Loosening the clasp it will allow it to possibly fit onto a slightly larger OD but tightening it won’t allow for a smaller OD.


Of Course!

The BNVD1531 ring is a lot bigger than all of the other mounts so that’s all it’s going to fit onto.

You’ll need to get the specific mount for the device you intend to use it on if it exists. Besides the ring size there can also be differences in the plate that the ECOTI locks into.

Trust me, if they could use the same mount across multiple systems then they’d do it. The caveat of course is that the -14 bracket works with almost all devices using pvs-14 lenses (except the 1531 of course lol) such as RNVG, DTNVS, Artemis, etc.

If that PhD Augee is the designer, I thought it would be sophisticated, given the price!

So in lay man's language, it's the same simple clasp of the 31a and under my kitchen sink on the hoses :)  that will scratch up my armchair commando housings, to create more "operator wear" to increase my BNVDs value during resale and be able to upgrade to SG's from TNVC.

For the 1531, to be more secure, precise and better hold bore sighting, I thought and hoped, the 1st clasp would have been molded to lock into the raised lip, and with a 2nd additional clasp, molded to lock into behind the lip, where the housing is lower with those raised horizontal grooves.

So it would be idiot proof and mount only one way- the same way, every time. With no fear that a single unmolded smooth bottomed clasp, is accidently a bit forward or back from the edges of the raised lips, during repeated installations and removals.

If it's molded to fit the lips, etc., as I would have liked, downside, then it wouldn't be a smooth bottomed clasp, so I couldn't fool around with it, and try to install on other devices, cameras, etc. just for fun., I could live with that for better fit.

I've been wondering how susceptible it is to being knocked off the BNVDs, if it takes a bump hitting my rifle rails or its mounted optics T2 etc.

Thanks again!

I wouldn't worry about it damaging/scuffing the 1531 but if you're concerned then use some thin tape or better yet stick a Nocorium wrap on the 1531

Most users just leave the mount on the device and remove the ECOTI when not in use. The ECOTI easily pops on/off.

If you're shooting passively or using a thermal scope then it's best to put it on your non-dominant eye and to the side 3 o'clock / 9 o'clock greatly lowers your odds of smacking it (or spitting dip on it).
