O'Five is an Iconic variant of the Techtronika SPT32 Grad in Cyberpunk 2077.


The O'Five is the signature weapon of Buck Arnold. He brags about the weapon to his friends, and that it served him well during his deployments. The weapon is classified as a "very heavy weapon", reducing movement speed and jump height by 15% and disabling the ability to sprint, dodge and dash.

O'Five has an iconic modifier that grants 16.6% Crit Chance and 10% reload speed for 5 seconds for each enemy affected by Burning. This effect stacks up to 3 times.

The O'Five has 50% increased Crit Damage and 30% additional Burn chance (40% total).

Because the weapon fires heavy explosive rounds, headshots and weakspots do not deal extra damage and force the user out crouching positions.


  • Beat on the Brat: Arroyo - With a sufficiently high Body attribute, you can goad Buck Arnold into betting the weapon, increasing the fight's buy-in to €$18,000. Upon winning the fight, Buck Arnold and his compatriots will attack. Upon eliminating Buck Arnold and the gangsters, you can retrieve your prize money from Buck's corpse and loot the weapon.
  • Alternatively, you can win the fight normally, and verbally taunt Buck into attacking you. Upon eliminating him and the gangers, you can retrieve your prize money and loot the weapon as if it had been bet.
