Jupp, pretty sure that is what he dropps. And no T2 wep. token.

Are you sure? The only saber I've seen from this boss is "Last bastion" which is a tier 1 saber, and not a columi (T2) token saber... And afaik it's only the last bosses in the Flashpoint HM's that drop T2 tokens, and HK47 is not the last boss... The rest of the bosses drop T1 quality items (Not tokens, but copys of the Tier 1 items, and sometimes the actual T1 item)
