While I would probably take any review from a national defense industry publication with a grain of salt, I just found an older article from Israel Defense that reviewed the new-ish 7.62×51 Negev NG7. Spoiler alert: they liked it a lot.

But, in fairness, the NG7 sounds like a hell of a gun. The NG7 is lighter than an M249 SAW, while packing a significantly bigger punch (7.62×51, instead of 5.56×45) and being far more comfortable to carry and hold.
