The TNAS-1 Puppeteer represents Tessera's most aggressive integration of neural technology with small arms. The weapon cannot be fired by trigger pull — it has no trigger. The Puppeteer fires exclusively through BCI neural command, with the operator's intent translated into firing decisions by an onboard neural interpretation engine. Think 'fire' and it fires. Think 'burst' and it fires three rounds. Think 'suppress' and it dumps a magazine at the designated area.

The rifle chambers 5.8mm caseless and features a free-floating barrel in a fully sealed receiver that eliminates environmental ingress. Without a trigger mechanism, trigger guard, or manual safety, the weapon's exterior is a smooth polymer shell with no external controls beyond a physical power switch. The BCI link handles everything — fire mode selection, round counting, malfunction diagnostics, and even thermal management alerts.

The Puppeteer is the most controversial weapon in production. Advocates praise its response time — neural firing commands bypass the mechanical delay of trigger pull, reducing time-to-fire by approximately 80 milliseconds. Critics argue that a weapon fired by thought is a weapon that can be fired by intrusive thoughts, hacked neural commands, or BCI malfunction. Tessera's liability waivers for the TNAS-1 are longer than the user manual.
