I don't think it's in use by the US military.
I've seen them for the past year or so among magazines directed at the Civilian NFA community. This leads me to speculate that they are ment for either Per '86 registered FN MAGs or Post '86 LEO M240 machineguns.
I'm guessing LEO as they would be in the market for such a modification.
I used to question why LEO would need a machinegun( case in Point the El Paso TX PD owns at least 1 M249). Then I looked in on what they are faceing in some parts of the country.
