The latest innovation to emerge from the guncad community is a stackable tin-can adapter that threads directly onto PG-7 warhead bodies, turning ordinary soup cans into modular bomblets for FPV drones. By marrying the inertial and electrical EDP-R fuzing already proven on RPG-7 munitions, the design lets builders daisy-chain multiple improvised payloads without custom machining, dramatically lowering the barrier to entry for small, precision-guided munitions. What looks like a simple 3-D-printed collar is actually a force-multiplier: it converts the everyday logistics of grocery-store metal into a scalable, air-delivered effect previously reserved for state arsenals.
For the 2A community, this is more than a clever hack; it’s a proof-of-concept that distributed, citizen-accessible manufacturing can replicate capabilities once monopolized by defense contractors. Where legacy militaries rely on tightly controlled supply chains and export-restricted components, open-source adapters like this demonstrate that motivated individuals can iterate faster and cheaper than procurement bureaucracies. The same tooling that lets hobbyists chamber oddball calibers or print replacement parts now extends to the payload domain, underscoring why magazine bans and “ghost gun” restrictions miss the larger point: once the underlying digital recipes exist, physical controls become theater.
Critics will decry the proliferation risk, yet the deeper implication is a leveling of the battlefield between centralized power and decentralized resistance. If a college student can turn a soda can into a drone-delivered submunition, then the asymmetry that once protected governments from popular uprisings shrinks by the day. The 2A was written for exactly this moment—when the tools of resistance migrate from armories to garages, and the right to keep and bear arms expands to include the right to keep and bear code.
