I posted this in the NSR thread, but thought it should have its own thread. These are the VLTOR VIS-KM (Key Mod) polylithic rails using the same technology and specs given (for the Key Mod) to Noveske to use on the NSR Key Mod rail.
These hopefully will be available mid Sept at the earliest. These are something I have dreamt of for a long time and am very excited about their availability!
They look OUTSTANDING:D
12"
12, 10, 9 & 7"
They do look outstanding!
Weights of each length please 
Also, prices if available. Ballpark or comparison prices to standard VIS would be nice if hard numbers aren’t available.
Thanks!
Looks nice. M4F, are these real pics or conceptual? Thanks.
Looks great. Vltor makes really good stuff. Does the 12:00 position have keyholes? If it does, is there room under the heat shield for screws or would that have to be removed?
sigh
I will pay to have…
My money is going to be safe until deep into '13, though, at the rate this project is going.
Looks good. Any idea on weights and dimensions?
These are “machined production pieces” and VLTOR is tooling up for these now.
When I know more I will share;)
Wow those look nice. Is the weight expected to compare to the NSR?
We should have an Assault Weapons Ban…on companies coming out with new products. 
:suicide: I just finish a new build a few weeks ago (with primarily Vltor parts) and now I see this.
Looks great though.

the above pictures are renderings, not of actual machined parts. since they’re now in the public eye, Vltor gave me the go-ahead to officially introduce the KM system to the public. i’ve started a new thread here:
