Chuck is a Tediore-manufactured legendary assault rifle in Borderlands 4 whose gimmick flips the trigger into a throw: attempting to fire lobs the gun like a fastball that erupts into a cluster of explosives on impact. If you want one, there’s a short, repeatable route tied to a specific Drill Sight and a nearby reset station that makes farming straightforward.

Borderlands 4 is available now on PlayStation 5, Xbox Series X|S, and PC via Steam and the Epic Games Store; if you need a direct store listing for PC, use the Steam page at store.steampowered.com/app/1285190/Borderlands_4.

Chuck legendary assault rifle (weapon overview)

Property Details
Rarity Legendary
Manufacturer Tediore
Type Assault rifle
Element Kinetic
Unique effect “Pitcher” — pulling the trigger throws the weapon; on impact with the ground or an enemy, four grenades spawn and explode.
Handling note Mind your spacing; throwing at your feet can down you.

Chuck farm location (The Pitted Stain Drill Sight)

The cleanest path to a Chuck drop is tied to a specific side activity and miniboss trio:

Step What to do
Reach the area Advance the story until you can access the region southwest of The Fadefields.
Find the marker Look for a Drill Sight icon positioned to the bottom-left of the map, just outside Fortress Indomita.
Start the activity Activate the Drill Sight named “The Pitted Stain.”
Boss checkpoint Clear the encounter; the capstone is a fight against three minibosses.

Complete this sequence once to unlock the encounter loop in the same location for farming.

Fast repeat method (Encore Machine reset)

After defeating the three minibosses inside The Pitted Stain, use the nearby Encore Machine to immediately reset the encounter. Re-enter, defeat the trio again, and repeat the reset. Continue this loop until Chuck drops.

Because this route begins at a fixed Drill Sight with a reset station steps away, it minimizes travel time and reloads, letting you focus on kill times and drop rolls rather than long runs between attempts.

Practical use: making the “Pitcher” effect work

  • Engagement distance: Treat Chuck like a midrange explosive. Aim to stick enemies or the ground in their path; the grenade cluster spawns on impact, not midair.
  • Crowd control: The four explosions can stagger packs and control choke points, especially in tight corridors.
  • Self-safety: Backpedal or side-step before throwing at close range to avoid the blast radius.
  • Element coverage: Chuck rolls Kinetic, so plan complementary elemental coverage on your other weapons for armor/shielded targets.

Availability and platforms (install the game)

Borderlands 4 is currently available on PS5, Xbox Series X|S, and PC. For PC players who need a direct purchase and install path, use the official Steam listing once at store.steampowered.com/app/1285190/Borderlands_4. Console versions are available through each platform’s store.

If you’re just starting out, you’ll pick from four Vault Hunters — Vex (Siren), Rafa (Exo-Soldier), Amon (Forgeknight), and Harlowe (Gravitar) — each with distinct action skills. Chuck’s throw-first behavior sits comfortably alongside gun-focused or ability-forward builds; it’s a reliable Kinetic option once you learn its spacing and reset cadence at The Pitted Stain.
