The 4-AC is among the best assault rifles in Ghost Recon Breakpoint thanks to its high accuracy, relatively low recoil, and extreme rate of fire. Unlike many other weapons, this carbine's blueprints can only be obtained from Maria's shop in Erehwon (or any Bivouac if you're playing Operation Motherland) for 45000 Skell Credits. It's a pretty hefty price, but it's well worth it if you want a weapon that's more than capable of dealing with every situation Ghost Recon Breakpointthrows at you.
