Sig Sauer MCX Rattler redefines compact firepower with its groundbreaking design, born from a US Special Operations Command PDW request. This ultra-lightweight, short-barrel pistol delivers unmatched versatility in a package smaller than any AR-style rifle.
Built on Sig's revolutionary MCX platform, the Rattler eliminates the buffer tube for maximum compactness. The 5.5" hammer-forged barrel is optimized for .300 BLK performance, while the aluminum M-LOK handguard provides modular attachment options.
