A new update is on the way for the PC version of PlayerUnknown's Battlegrounds. Unlike the last few patches PUBG Corp. has rolled out for the title, which generally focused on introducing new content like the recently added assault rifle QBU, Update #19 primarily addresses bugs and makes various other quality-of-life improvements to the battle royale game.

In terms of the latter, PUBG Corp. has made some tweaks to inventory management, specifically in regards to weapon attachments. Following the update, removed or replaced attachments will drop onto the floor if a player's inventory is full. Players will also be able to detach all attachments by pressing Alt while right-clicking on a weapon.
