SIG Sauer M400 Pro 16" Folding Stock Carbine

The SIG Sauer M400 Pro 16" Folding Stock Carbine is a purpose-built modern sporting rifle engineered for operators who demand reliability without compromise. This platform serves law enforcement, military personnel, and trained civilian shooters requiring a compact, modular carbine that performs in dynamic tactical environments. The folding stock design enables rapid deployment from confined spaces—vehicles, breaching positions, or storage-limited operations—while maintaining full handling and accuracy when extended. SIG Sauer's reputation for precision and durability backs every rifle that leaves their manufacturing facility.

Built on a proven direct-impingement operating system, the M400 Pro delivers consistent shot-to-shot performance through field-tested engineering. The 16-inch barrel balances velocity and handling, offering superior velocity over shorter profiles while maintaining controlability in close-quarters scenarios. The folding stock mechanism—engineered for positive lock and repeatable fit—reduces overall package dimensions without sacrificing ergonomics or cheek weld consistency when deployed. Modular rail systems and flat-top design support optics, lights, and accessories critical to modern tactical operations. Every component is finished to withstand harsh environments and repeated deployment cycles.

Operators in patrol, tactical response, and duty-rifle roles will find the M400 Pro's compact profile and proven reliability invaluable for vehicle mounting, breaching teams, and situations where space is limited. The rifle's modular architecture allows field customization—rail-mounted accessories, optics, and ammunition storage integrate seamlessly. Shooters accustomed to AR-platform ergonomics will experience zero learning curve; controls and maintenance procedures remain standard across the platform. This carbine pairs effectively with standard 5.56 NATO/.223 Remington ammunition and accepts industry-standard AR magazines, ensuring supply chain compatibility and operational flexibility in the field.
