Argon Scope is a rare rifle mod that increases critical chance while aiming for a brief time upon a headshot.


Rank Critical chance Duration Cost
0 +22.5% 1.5s 2
1 +45% 3s 3
2 +67.5% 4.5s 4
3 +90% 6s 5
4 +112.5% 7.5s 6
5 +135% 9s 7


  • Argon Scope is additive with similar mods. For example, a CorpusSniperRifle Snipetron with a max rank Argon Scope and Mod TT 20pxPoint Strike will have a 30% × (1 + 135% + 150%) = 115.5% critical chance.
  • Argon Scope will trigger upon headshots, i.e. any weapon hit to an enemy's head, whether the target survives or not.
    • Headshots will refresh Argon Scope's timer.
    • The headshot that triggers Argon Scope will not benefit from the buff itself (unless the buff was already active).
  • If activated, Argon Scope will display an icon timer beside the player's health UI, and the Warframe will be briefly surrounded by a flashing energy ribbon.
  • Can be installed alongside Mod TT 20pxPoint Strike and Mod TT 20pxCritical Delay in order to further increase the critical chance.


  • Rank 4 has a few unnecessary decimals.
