FN 509 Reliability Test
This guide outlines the 'torture test' protocol used by Military Arms Channel to evaluate the FN 509's reliability under extreme conditions. The test involves sequential immersion in water, sand, dirt, and mud, followed by a 'Gauntlet' of repeated adverse exposures. The FN 509 exhibited significant reliability issues, including failures to fire, trigger reset problems, and feeding failures, leading to an 'abysmal' performance rating compared to other tested firearms.
