MOSCOW

THE automatic Kalashnikov, the world’s most abundant firearm and a martial symbol with a multiplicity of meanings, turns 60 this year. In some places this is cause to shudder. In Russia it is treated as a milestone to celebrate, and a chance to cry foul.

Once strictly Communist products, the AK-47 and its offspring are killing tools so durable and easy to use that they were heralded as achievements of state socialism and industrial might. Uncoupled from the laws of supply and demand by their origins in planned economies, they flowed from arms plants in the tens of millions, becoming national defense and foreign policy instruments for the Soviet Union and allied states.

But the 60th birthday party has displayed the rifle’s evolving place in both the market and the Kremlin’s mind. These days the Kalashnikov is seen through capitalist lenses, and argued about in ways that could not possibly have been envisioned by its Communist creators.

In cash-hungry Russia, Kalashnikov is now an informal brand. And as purchases of Kalashnikov rifles and their derivatives continue on foreign markets, Russian arms manufacturers and exporters worry not about ideology and world dominance, but over sales opportunities lost.
