Introduced in 2005, the Sako Quad uses a set of four barrels and two magazines to rapidly interchange between 22 Long Rifle, 22 Winchester Magnum, .17 HMR and .17 Mach 2 with minimal tools. Manufactured without sights, with color coded rings and dots on the barrels, stock and magazines for ease of recognition, a set of integral rails on the receiver, and a textured one-piece pistol grip stock with sling studs and a rubber buttplate. With a Sako-branded metal case, allen wrench, sling, cable lock and papers.
