When Beyond Light was released, a huge portion of the game was sealed away. A big part of the raids, quests, and activities was removed. However, there is a new vendor that allows you to get all of the lost weapons in for some materials. Farming them of course takes time and many times requires completing Raids and Nightfall strikes. If you missed those legacy weapons from the back when they were available, order our Destiny 2 Legacy Weapons Boost services and we will get them for you in no time!
