Detachable Magazine (30-round capacity) — 'thirty-round clip' (Lincoln Memorial scene, "Five Votes Down")

A slim, rectangular metal detachable magazine sized to hold thirty cartridges; described only in dialogue and never handled on-screen. Characters evoke its thirty-round capacity as the defining physical trait—stout, utilitarian, and engineered for sustained semi-automatic fire. The mention snaps through the Lincoln Memorial confrontation: Richardson invokes the 'thirty-round clip' as a concrete example of the weapons the proposed bill leaves accessible, using its capacity as a moral fulcrum rather than a manufactured detail. No markings, finish, or wear are specified; its presence registers entirely through speech and the emotional reactions it provokes.
