The Tessera TKS-SL is a semi-automatic shotgun chambered in 12 gauge with BCI smart-link integration, biometric authentication, and Tessera's proprietary variable-choke system that is controlled electronically through the neural interface. The shooter can adjust the choke — and therefore the shot spread — by thought alone, selecting from five preset patterns between shots without touching any physical control.

The Adjudicator's neural choke control is the weapon's defining feature. Where the Arcturus Scatterstorm uses electromagnetic fields to shape its flechette pattern, the TKS-SL uses a conventional barrel with a mechanically actuated choke ring driven by piezoelectric motors. The five presets range from 'cylinder' (maximum spread) to 'extra-full' (tightest pattern), and the shooter selects between them through BCI command. The transition takes approximately 0.3 seconds — fast enough to adjust between shots in a deliberate engagement.

Tessera developed the Adjudicator for their senior tactical teams as a single weapon that could replace multiple shotgun configurations. An operator with a TKS-SL can breach a door with a wide-pattern slug, clear the room beyond with buckshot on cylinder choke, then tighten to extra-full for a precision engagement at hallway distance — all without removing their hand from the grip or their eye from the sight picture.
