DIA DB175AK271 5.56 16" Carbine

The Diamondback DB175AK271 5.56 16" carbine is purpose-built for law enforcement, military, and civilian tactical operators who demand a reliable platform in compact form factor. This 5.56 NATO rifle delivers the firepower and ergonomics required for duty, training, and defensive applications where a shorter sight radius and reduced overall length provide tactical advantage in vehicles, buildings, and close-quarters scenarios. At 8.4 lbs unloaded, it balances controllability with mobility—critical for professionals who carry extended shifts or operate in dynamic environments.

The 16-inch barrel chambered in 5.56 NATO provides superior velocity over pistol-caliber alternatives while maintaining a handling length that exceeds AR pistols in accuracy and sight radius. This barrel length is the industry standard for duty carbines—it delivers 2,800+ fps muzzle velocity with standard M193 or M855 ammunition, ensuring consistent terminal performance at duty distances (0–300 yards) and improved shot placement through better ergonomic controls. The Diamondback DB175AK271 features a modern AR-platform design with mil-spec compatible rails, receivers, and charging handle geometry, allowing field-proven accessories and upper/lower interchangeability with standard AR-15 parts ecosystem.

Law enforcement agencies, military personnel, and trained civilians seeking a duty-grade 5.56 carbine will find the DB175AK271 immediately familiar and combat-proven in platform fundamentals. This rifle integrates seamlessly with standard AR-15 optics mounts, rail systems, magazines, and ammunition logistics already established in professional armories. Whether configured for patrol, entry, or defensive response, the Diamondback DB175AK271 provides the reliability, accuracy, and ergonomic foundation that veteran operators demand from a modern rifle.
