Mk v stun guns

I'm finding the mk10 taggeco's a lot worse at the moment. Not many characters need them, but when you're stuck on that one last slot it's a major bottleneck. Just like guns they are only available in Guild Event, Shard, and Shipments (for crystals). Unlike guns they are not farmable via a light or dark node. So I basically just wait for them to pop up in those stores, or drop in tank or sith (a longshot it seems). Shipments keeps teasing a full one for 1250cr on a daily basis, though I only need 7.
For gear like guns and mk10 taggecos, it's good to have a constant, small buffer of tokens in shard and guild event, and prioritize those for purchase over more accessible gear like carbs in those stores.
