The RAI 300 (Research Armament Model 300) rifle was a bolt-action rifle designed by a team of weapons designers lead by J. Haskins between 1981 and 1982 as a sniper rifle for the U.S. Military. Unlike most military sniper rifles, the Model 300 was purpose-built for the military, not reworked from an existing civilian rifle - another such sniper rifle was the Soviet SVD. Though not adopted in large numbers by the U.S., the weapon served as a testbed for new sniper ammunition. The cartridge originally used, the 8.58 x 71 mm, was eventually developed by the Lapua-Nammo Oy company in Finland into the .338 Lapua Magnum.
The Model 300 was a bolt-action, magazine-fed weapon, featuring a steel receiver with a rotating bolt. The bolt had 3 long lugs which locked into the receiver walls. The weapon could use one of two cartridges: the 7.62 x 51 mm NATO and the 8.58 x 71 mm. Switching between calibers was relatively simple, requiring that only the barrel and bolt head be replaced. The Model 300 featured a detachable scope mount, heavy precision barrel, a folding bipod, a fully adjustable trigger and could be disassembled for ease of carry and storage.
