Apex Attachments are earned by levelling one weapon all the way to maximum. They are equipped separately from standard attachments and do not consume an attachment slot, but they do block certain standard slots on that weapon, which is listed in the last column.
What they are for
Activision describes Apex Attachments as changing how a weapon performs rather than nudging its numbers: some turn a familiar platform into a different combat role, others add alternate fire modes or integrated equipment that standard Gunsmith customization cannot reach. Because a weapon needs a set number of levels to earn its Apex, the fastest Apex to reach is on the weapon with the fewest levels.
