I purchased the Amalgam, Trencher bundle. When I go to the gunsmith it isn't visible. The armory has the weapon and I can use it just can't change attachments. Maybe need higher weapon level. Ran up to level 10 still no gunsmith. On the select weapon screen it has to unlock I need 3 kills near smoke with LMG 15 different matches. I bought the weapon shouldn't have to fight for it again. New guy here, Help?
