The Meridian Municipal Supply AG-7 is an agricultural cattle prod, manufactured for livestock management in the urban farming cooperatives and vertical ranching operations that supply GLMZ's food chain. It is a 90-centimeter fiberglass-and-ABS rod with a two-prong stainless steel contact at the tip, designed to deliver a sharp, brief shock to the flank of a large animal — sufficient to redirect behavior without causing lasting harm to the animal or its market value. It runs on two standard D-cell battery equivalents, has no charging port, no digital components, and no safety mechanism beyond a simple sliding power switch. It costs Φ15 at any agricultural supply outlet and is available without any documentation whatsoever.

The AG-7 was never designed as a weapon. It was designed to move cattle through chutes. That it has become one of the most common improvised defensive and offensive tools in Tier 1 and lower Tier 2 is a testament to the gap between what people can afford and what the formal weapons market provides. The shock output is lower than dedicated security batons — approximately 30,000 volts at very low amperage — and the contact range is shorter, but it is immediate, it is reliable, and it leaves no purchase record that flags a personal protection permit database.

Meridian Municipal Supply has periodically faced pressure from municipal security contractors to add purchase restrictions or tracking to AG-7 units, given their prevalence at crime scenes. The company has consistently and successfully argued that the AG-7 is a farm tool and that restricting it would harm legitimate agricultural operations in the city's food-production districts. This argument is legally sound and practically convenient for everyone involved.
