Although only a few weapons will task you with maxing them to unlock their Aftermarket Part challenge, you will need to max out your desired weapon nonetheless to be able to equip the attachment. You can also get two Optic Aftermarket Parts —the Cronen Intlas MSP-12 and the Intlas Cas-14— as Armory Unlocks.
