I've seen one KA M4A1 at sub 300$ (280 if my memory's good) just yesterday.
Unfortunately I really don't remember where; one of them retailer having a special I guess.
But all in all we can't give you urls until you verified status kicks in
300$ is still good - but as said earlier, wait a bit and you're more likely to save even more
