The Bor, formerly known by the codename of Alex during development, is a Polish sniper rifle.
After Poland joined NATO in 1999, it became clear that Poland needed a new weapon that would meet NATO standards, so starting in 2000, a new sniper rifle was developed at Ośrodek Badawczo Rozwojowy Sprzętu Mechanicznego by Aleksander Leżucha. With the financial backing of the Polish Science Research and Information Technology Ministry, Leżucha put together his new rifle to be manufactured by ZM Tarnów.
The first prototypes were ready by summer 2005 and showed off at the 12th International Defense Industry Exhibition MSPO in September the same year, under the name of Alex. The rifle began production the next year. By 2007, the Alex had passed all tests to be accepted into Polish service, and was designated the Bor, with 36 rifles to be acquired by the military that year. In 2008, 81 rifles were ordered chambered for 7.62×51mm NATO that were to be delivered by 2010; another 55 more done to 7.62mm NATO specifications were ordered in 2011 and were to be delivered in 2013.
The Bor is a bullpup bolt-action sniper rifle fed from 10-round detachable box magazines. The weapon has a front-mounted bipod and an adjustable monopod at the rear. A Picatinny rail is located on the top, which is able to fit a telescopic sight, though no backup iron sights are provided. Due to its bullpup configuration, the weapon is significantly shorter than similar weapons, but retains its full barrel length, which helps to reduce weight; a free-floating fluted barrel helps to reduce weight even further. The Bor has a dual-baffle muzzle brake that claims to reduce up to 30% of felt recoil. A Leupold 4.5-14×50 telescopic sight is fitted as standard.
