B.A.R replacer for combat rifle?

I like the idea of the combat rifle and all but hate what Bethesda did to its premise making it a fallout 4 gun, so basically just something like what junkmaster did to the vanilla combat rifle and just gave it cooler attachment features to resemble an old B.A.R or colt monitor

I feel like the design would have to be merged with the M1A or maybe a modern rifle (XM8, SCAR) to give the illusion of it being advanced. That's just me tho
