Mausers are widely considered the finest bolt-action military rifles ever made. The first Mauser went into service in 1871. The last production Mauser, the 8 mm Yugoslavian M48, was produced in large numbers from 1948 until the late 1950s. By then, semi-automatic rifles rendered bolt-action designs obsolete. Thousands of factory-fresh M48s were coated with heavy preservative grease and placed in storage for 50 years. The fall of the Iron Curtain released this stockpile of mint condition "Yugo Mausers" onto the retail market. The M48 front sight is a standard male post friction-fitted into a female dovetail and sheltered by a round hood. The front sight performs all M48 windage adjustments. The rear sight makes ladder-style elevation adjustments with a sliding tangent. The adjustment scale is inscribed with range increments from 100 meters to 2,000 meters.
