The weapon received the code name Alex during development, after the name of the lead designer Aleksander Leżucha, creator of the 12.7×99mm NATO Wilk anti-materiel rifle.

After 1999, when Poland became a member of the North Atlantic Treaty Organization, there was a need for new firearms for the Polish Armed Forces compatible with NATO standards.

The work on the Alex had financial backing of the Polish Science Research and Information Technology Ministry in a joint venture construction with the manufacturer OBR SM Tarnów.

[citation needed] In 2008 the manufacturer received an order for the delivery of a batch of 81 Bor rifles chambered for the 7.62×51mm NATO cartridge by 2010.

Early in 2008 the Mechanical Equipment Research and Developing Centre in Tarnów completed the design work and in June 2008 the first prototype was assembled.

The eventual introduction of weapons chambered for the specialized .338 Lapua Magnum rimless bottlenecked centerfire cartridge developed for military long-range sniper rifles will be a novelty in the Polish Armed Forces.

As such the Alex Tactical Sport is adapted to the needs of sportsmen and law enforcement and the design has been simplified – reducing the number of rifle components.

The Alex Tactical Sport weighs 5.3 kg, has a 660 mm long barrel and feeds from a double stack 10-round box magazine.
