From The Manufacturer/Wikipedia/People Smarter Than Us:
The SSG 69 line of rifles, including the STEYR SSG 69 PI and the STEYR SSG 69 PII, mirrors many years of STEYR MANNLICHER’s firearms manufacturing experience.
Their precision and robustness set a trend internationally, for a new generation of modern precision rifles. Despite the fact that their development originated some time ago, the SSG 69 series of precision rifles remain internationally high in demand.
