Most LMGs are supposed to post up, mount cover, and ambush.
You're not supposed to sprint in and engage in CQB with shotguns and SMGs unless you're using the M123.
If you kit the M123k out with a 200 round belt and a bunch of hip fire shit it rips HARD in CQB though.
It can hit 90 hip fire and still get the 200 round belt.
