unlocked the TracShot Directive Carbine, and hate it. the underbarrel should be interchangeable. and with the slower movement speed(-50%), id rather just stick with the Jaguar (-25%)
TRAC-Shot is an amazing carbine. It's a straight upgrade from TRAC 5, which already is very strong. It's one of the best directive weapons in the game. You're just spoiled by the Jaguar, which is also nearly overpowered.
changing out the under barrel to smoke or a grenade would be fun. especially when the description says "multiple attachments" and there isnt any other than a shotgun
