Sig MCX Torture Test!
This Sig MCX torture test subjected the 5.56mm rifle to a rigorous mud and grit challenge. While initially reliable, the rifle experienced significant cycling failures when exposed to mud with the dust cover open, attributed to grit entering the tight dual recoil spring channels. After thorough cleaning and lubrication, the MCX returned to full functionality, proving to be accurate and ergonomic but sensitive to extreme environmental contamination.
