I think the BAR is overrated. The Bren gun was a superior light machine gun.
and the Zb26 was superior to the Bren, BAR, etc.
I take it that you haven’t fired the BAR..
It is steady, controllable, and very effective. I was able to see the strikes of my hits through the peep sight when firing in the prone and on the bipod. Had no trouble putting round after round through a bunker’s embrasure (about 6 inches) at 150 meters.
A whole lot lighter than a Bren too.
