Sorry, but Negev is so 2011. You better focus on MSBS variants, because that's what's going to fill the 5,56 "LMG" bracket.
I'm talking about the LSW variant, the one with 60 round Surefire magazine on picture above.
And UKM-2000P will remain our standard 7,62 LMG, since the army can't stop buying them.
