Description
This SIG Sauer MCX in 5.56 NATO is a highly configurable, battle-proven platform, optimized for tactical performance and modular upgrades. This setup features a Geissele Automatics SSA trigger already installed—known for its crisp break and reliable reset—making it an excellent choice for precision-driven shooters.
Also included are two handguards: the installed Midwest Industries M-LOK rail system and an additional OEM-style MCX handguard with integrated rail section. The rifle features SIG’s lightweight folding stock for compact transport and storage, and a durable polymer magazine is already included.
Ideal for serious shooters seeking a versatile rifle for training, range days, or defensive preparedness, this MCX offers premium performance out of the box with enhancements that typically require aftermarket upgrades.
