An LMG and a FA battle rifle are not the same thing, nor are they used for the same purposes. We had 3 rnd burst, which I found just as useless as a FA battle rifle in the hands of the general infantryman. LMG are heavy and need lots of ammo weight to be used much. Without lots of good training and practice FA fire from either platform is quite inaccurate compared to semi auto. Before the “tactical trainers” pile on me, I lived this as an infantry Marine. There is a place for FA personal weapons among highly trained orgs with a large training budget, but actual “door kickers” are a very small fraction of any organization. FA for a fun, absolutely, like a 200mph car. Go as fast as you can afford.
