SIG Sauer M400 5.56 16" 10-Round Stainless Rifle

The SIG Sauer M400 5.56 16" 10-Round Stainless Rifle represents a purpose-built platform for shooters and operators who demand reliability in a modern tactical rifle. Chambered in 5.56 NATO, this semi-automatic rifle delivers the precision and durability that law enforcement, military personnel, and civilian marksmen have come to expect from SIG Sauer's engineering. The 16-inch barrel provides an optimal balance between velocity, maneuverability, and sight radius—a configuration proven effective in professional and recreational shooting applications for decades.

Built on a direct-impingement system with a stainless steel barrel, the SIG Sauer M400 delivers consistent accuracy and enhanced corrosion resistance in demanding environments. The 10-round magazine configuration reflects California compliance standards while maintaining the rifle's tactical profile and ease of handling. The stainless construction reduces maintenance intervals and extends service life in wet or salt-air conditions—critical for field operators and hunters in challenging terrain. Modular design allows for future accessory integration, enabling users to customize optic mounts, handguards, and furniture to suit specific mission requirements.

This rifle is ideally suited for law enforcement patrol rifles, precision hunters, and sport shooters seeking a proven platform with minimal learning curve. The compact 16-inch barrel makes it suitable for vehicle-based operations, building clearance, and quick-response scenarios where a full-length rifle would prove unwieldy. Whether used for training, duty, or recreational marksmanship, the SIG Sauer M400 5.56 provides a reliable foundation that performs consistently across temperature extremes and extended firing sessions. Compatibility with standard AR-platform accessories ensures users can source replacement parts and upgrades through established supply chains.
