Borderlands 4 Frangible Legendary SMG Guide: How to Get It and Best Rolls

The Frangible Legendary SMG in Borderlands 4 is one of the strangest weapons you’ll come across. Unlike most legendary guns, it displays no visible damage numbers, perks, or manufacturer parts on its stat sheet. The only way to figure out its traits is by actually using it in combat.

In my case, the weapon rolled with Torgue’s Sticky Magazine and Tediore-style accessory parts — though it can vary for each drop. While its hidden stats make it look like a potential powerhouse, the truth is a bit different.

How to Get the Frangible Legendary SMG in Borderlands 4

Acquiring the Frangible in Borderlands 4 is entirely RNG-based. As of now, it doesn’t belong to any fixed boss loot pool or dedicated activity.

·         I personally got mine while farming the Vault of Radix,

·         A friend of mine pulled one from a golden chest,

·         Other players report random drops from boss caches.

Since there’s no guaranteed farm, the best approach is to:

·         Play on Ultimate Vault Hunter Mode to improve legendary drop chances.

·         Farm easy bosses repeatedly, since their caches may drop the Frangible SMG.

Is the Frangible Worth Using?

Calling the Frangible “broken” can be misleading. Yes, it deals damage even though its stats are invisible — but compared to other legendary SMGs in Borderlands 4, it simply doesn’t hold up.

When I tested it against Radix, the gun failed to break half the boss’s shield, even with Vex’s vampire build and the correct elemental matchup. This makes it more of a collector’s item or meme gun than a serious endgame weapon.

Most players will likely stash it in the bank rather than use it in their main build.

Best Frangible Legendary SMG Roll in Borderlands 4

Since most of its stats are hidden, there’s no clear way to determine a god roll Frangible. The one element you can look out for is the elemental burn effect, which influences its damage type.

So far, drops have included:

·         Shock (e.g., mine had an 8% chance to deal zero Shock DPS)

·         Incendiary

·         Presumably Cryo and other elements

While the elemental type makes a difference in combat, the gun’s overall DPS remains underwhelming compared to other top-tier SMGs.

The Borderlands 4 Frangible Legendary SMG is one of the game’s strangest weapons — with hidden stats, inconsistent performance, and RNG-based acquisition. While it’s a fun novelty and worth keeping for collection purposes, don’t expect it to outperform the game’s stronger legendary SMGs.

If you do get your hands on one, look for the elemental burn variant that best fits your build. Otherwise, consider it more of a quirky loot piece than a must-have weapon.
