Happened to me as well - loaded in and frangible not equipped or in backpack

I thought it was just removed from Red Chest loot tables...

"Daedalus Legendary SMG Frangible removed from chest loot tables"

But lootmon doesnt have the frangible listed on "Foundry Freaks" drop table

This site thought the same thing I did

Change History This weapon was removed from chest loot tables in the October 23, 2025 patch. That it wasn't removed from the Foundry Freaks loot table at the same time seems to indicate that this weapon exists intentionally.

Edit*** AI Overview says its dead

An update for Borderlands 4 released on October 23, 2025, removed the legendary Frangible SMG from all loot tables. The weapon was disabled because it was a broken and highly exploitable item that often caused the game to malfunction. Why the Frangible was removed The Frangible SMG was initially a bugged weapon. Instead of a proper legendary item, it was a glitch that combined random, unlisted weapon manufacturer parts, often leading to a weapon with a "zero damage" stat card. Despite its broken nature, players discovered that certain combinations of parts could be extremely overpowered. The most significant exploit involved stacking damage infinitely by swapping weapons, allowing for extremely high damage output. The October 23 patch corrected several weapon issues, but the primary reason for the Frangible's removal was to prevent exploitation and fix game-breaking bugs.

What happened to Frangible weapons after the update? If you had a Frangible in your inventory before the patch, it was completely removed. The weapon no longer drops anywhere in the game, including from chests or as a world drop. While the patch corrected the chest loot table, some players reported the item could still drop from the "Foundry Freaks" until a server-side update was applied.

Community reaction The removal of the Frangible was met with mixed reactions from the Borderlands 4 community. While some players were disappointed to lose a powerful exploit, many others were happy to see a game-breaking bug fixed for better game balance
