Borderlands 4 Weapon Parts Guide | Licensed Parts Explained
Borderlands 4 changes how guns work with the new licensed parts system. Instead of each weapon being locked to a single manufacturer’s gimmick, certain parts now carry those traits across brands. This lets you find hybrid weapons and new builds that weren’t possible before.
Licensed Parts System Overview
Every gun is made from parts like barrels, mags, grips, and accessories. In Borderlands 4, one or more of these can be licensed from another manufacturer. That part adds its original trait to the weapon, such as ricochet crits, sticky gyrojets, or elemental swaps.
Atlas, COV, and Hyperion no longer create full weapons, but they appear as licensed parts so their mechanics still show up in the loot pool.
