The Magpul Illumination Kit came with a short 3-slot section of rail.
I got curious about what use I could put it to and decided to see if mounting a GG&G Sling Thing there would be comfortable.
The sling location is similar to where I had a QD socket on the LaRue 4-rail.
Links to Midway USA because they're in the NYFS boycott.
Nope, don't like it. I keep using the sling mount as a thumb rest and that puts my hand no place near the controls of the light.
