Special Weapon Effects

I swear, that has never happened before. – Fires a single powerful projectile. 50% chance to not consume ammo when fired.

Usage & Description\

Due to the relatively low power of sniper rifles in Borderlands 3, this weapon can be a very effective, high-powered alternative, with damage that far out-performs similarly-leveled weapons. It also generally spawns with a 3.5x scope which is typically more useful than the extremely high magnification on most sniper scopes.


  • Although not listed on the item card, this weapon retains the normal Jakobs perk of ricocheting a round at a nearby enemy on critical hits.
