Black Hole gear - rifle

Hi,
i'm 90% of time PVPer, so i'm pretty newbie in PVE department. I have saved BH commedations from Correlia dailies, thought to buy a rifle (i'm Operative).
But rifle from BH vendor doesn't require BH commendations but some 'unassembled rifle' or something like that. Where do i get that? I have like 66 comms now, btw.

Thank You

Most of the best gear is going to require the Unassembled Tokens. These drop only from Hard Mode Flashpoints (4 person group) and Operations (8 or 16 person group).

The gear that you can get at end game is tiered - there are 4 tiers currently and each tier has 2 versions, 1 that has a set bonus (a bonus to your existing abilities that unlock automatically once you have 2 or 4 pieces of your set) and 1 that does not.

These are the current tiers, set bonus version listed (non-set bonus in parentheses) and where they are found:

Tionese (Xenotech) - drops from story mode level 50 flashpoints
Columi (Exotech) - drops from the final bosses in hard mode level 50 flashpoints and from story mode operations
Rakata (there is no non-set bonus version of this) - drops from hard mode tier 1 operations and story mode tier 2 operations
Campaign (Black Hole) - drops from hard mode tier 2 operations

Starting at the Columi level, the bosses will drop an Unassembled Token that can be turned in to a vendor on the fleet to get the appropriate piece of gear. The Columi and Rakata tokens are restricted by class also. The Campaign tokens are not restricted by class.

In addition to that, there are certain pieces of gear that cannot be obtained with commendations. These include the main hand and off hand items (except Tionese level) and all of the Rakata gear with the exception of implants and earpieces (and belt/bracers if you have the appropriate crew skill). The only way to obtain these is by completing the relevant flashpoints or operations where the tokens drop, hoping it is one for your class and that you win the roll for it.

Hmm, so only from loot. I guess for now war hero barrel will have to do :-)
thanks for explaining

Btw. these looted tokens are tradeable or not?

They are not tradeable.
