The Mk-18 SA-ASR was initially designed in 2010 using SWORD’s proprietary short-stroke gas piston system, modern advances in metallurgy, and an unbelievably precise barrel manufacturing process. Long before the market demand emerged, SWORD’s veteran research and development cell determined that a requirement would exist for a versatile semi-automatic platform that performed beyond typical medium calibers, while still delivering performance metrics closer to those in the heavy category. Eventually, even USSOCOM came to the same conclusion with their pursuit of systems chambered in these calibers. The SA-ASR delivers a powerful, reliable, and mobile platform that provides the end-user with the ability to reliably engage targets at or beyond a statute mile (1.609 km) depending on ammunition selection.

 SWORD Defense Systems offers this platform in .300 Norma Magnum, .338 Norma Magnum, and .338 Lapua Magnum.
