PSR features a custom firearm build: a Nexus Evo Gen One CZ Scorpion with a bearing delay and a discontinued CZ Bullpup conversion kit. This configuration results in an extremely compact, suppressed submachine gun praised for its unique, "cyberpunk" aesthetic.

He strongly advises that the reinforced aluminum Nexus Evo receiver is necessary for safety. Using the original plastic Scorpion with this bullpup kit is dangerous, as the action sits right next to the shooter's face, risking catastrophic injury from an "out-of-battery" malfunction.

While the new configuration is highly concealable, the shooting experience is rated as suboptimal. This is mainly due to a poor, mushy trigger caused by the extra linkage, and significant gas blowback directed at the shooter’s face. In the end, he concludes that the conversion is high on visual appeal but sacrifices practical shooting effectiveness.
