INSIGHT MRDS????

[Skyfire1201]

Botach was running a Cyber Monday sale, and I decide to take advantage of it and get a KZ Insight MRDS mount as well. It has a spring loaded knob that tightens a 1" long clamp that grabs onto the rail, the setup looks pretty sturdy. The interior is hollowed out, which makes the mount fairly light. Since the two mounting screws on the MRDS are situated towards one end of the sight, any mount for it is basically can only mount in one direction. The KZ mount is no exception, it mounts with the knob on the left side, which is alright for AR15 type weapons, but not so great on weapons with charging handle on the left side (such as the AUG, FS2000, and FN-SCAR).

On the kitchen scale, the KZ mount by itself weighs 2.47oz. Comparatively, my Insight factory mount + YHM makeshift mount weighs 3.81oz. So the KZ mount is lighter by ~40%, which is expected given its design. I don't have separate weight for the factory mount, but the ADM Insight mount is 2.10oz as claimed on their website. BTW, the MRDS sight itself with the shroud is 1.38oz, so with the KZ mount, the whole package is 3.84oz or 109g. Just for the sake of comparison, the Trijicon Doctor w/o mount is 0.9oz, Trijicon RMR w/o mount is 1.2oz, and Aimpoint H-1 with factory rail grabber mount is 3.70oz (105g).

This mount seem to be just a tad higher than the makeshift mount I put together, and makes for a pretty low 1/3 co-witness mount. It's not a "true co-witness" mount as claimed on the Botach website, it will be if it's 1/8" lower.

Here's some pics with the mount on my SR15. I haven't adjust the sight so the dot is not centered, that's not the mount's fault.

Are you saying that the riser + mount for your previous installation weighs less than the KZ mount alone?

Wanted to double check that because it sounds hard to believe!

And, BTW pics aren't displaying.

No, I mean the old mount I have, which is the factory Insight mount + YHM Eotech mount is about 1.5oz heavier than the KZ, which is expected since the KZ is hollowed out.

I guess the way I phrased it was kind of confusing, it's been fixed. Thanks for pointing it out.

Nice review and nice correction! I would love to have an alternate knob on this thing but really I'm nitpicking at that point. It's a solid mount, provides a nice 1/3 lower co-witness (perhaps a bit lower than that), and is nice and lightweight.

Can't wait for my second MRDS setup to arrive!

bumping the thread, any news from ADM for a co-witness mount ?

I haven't heard anything from ADM and it's been a year of pestering them to release one......

In the meantime, I'm all about the KZ mount at Botach. Frankly, I'm very pleased with the entire setup and now have 3 KZ mounts with MRDS's in aluminum protective shrouds. By far the best lightweight CQB setup I've seen.

I have tried quite a few optics on my Remy 870 and the Insight MRDS in it's standard mount seems to work the best for this application. The weight is almost non-existant, the height is perfect, the protective shroud makes it bomb-proof, & the dot is just the right size. The battery life could be better but you can't have everything.

What sort of battery life are you getting? The MRDS, when put away in the dark or stored with the cover, should give you over a year of continuous run time. Are you not getting that?
