Battlefield 1, the new entry of the series developed by DICE, is going to be packed with content just like previous Battlefield games, and we still don't know about everything that will be available in the game at launch. Some fans, however, are just not able to wait for more information to come in, and have taken matters in their own hands, revealing some previously unknown details in the process.
Reddit user CodeSanta has recently provided a list of all the weapon attachments, sights and other customization items that will be available in Battlefield 1. As the list has been obtained through data mining, things may change in the final release of the game. Reddit user krzgui cleaned up the list provided by CodeSanta, making it much easier to read.
