M1903 Springfield?
Japanese Type 89 might count. Howa was originally a manufacturer for AR18s (and a damn fine one accord to all I've read) so they had the full technical package and tooling for them. When Japan was looking for new rifle they (seem to) have basically shrugged, acknowledged they have no gun designers in the country, didn't want to pull a Britain, and accepted an AR18 with a few changes (biggest being that it takes STANAG mags). Of course by this time the patents had expired so if it even counts as a bootleg is questionable.

I know Type 56s differ simply because they're AKs, but even the ARs?

"Unlicensed" has a lot of implications when nearly every gun is based on some now-expired JMB or Armalite patents if it wasn't dervied from some Soviet shit. That's not even counting stuff like the 1911/M1 Garand/M1 Carbine/AR where you can get the specs from the US government over the original makers.
