Ah yes, the original Burst Assault Rifles from the very early days of Fortnite.
Before they got swapped with an updated model of FAMAS and AUG in Chapter 2, and before they eventually all became FAMAS, with AUG being its own weapon now in Chapter 3.

Yeah, it has been years ever since then and we're in Chapter 3 already, and yet we've finally got these ported over to SFM now, man.

These 2 weapons were ported by my friend Joseph inkling-15 himself, I just helped uploading them.
