The Diamondback DB165AL101 DBX 5.7x28mm rifle represents a modern approach to compact, suppressor-ready platform design built for shooters who prioritize modularity and ergonomic control. This 8-inch barreled rifle delivers the ballistic efficiency of the 5.7x28mm cartridge—a round developed for specialized applications requiring reduced recoil, hearing-safe subsonic performance, and minimal collateral risk. The Sports South exclusive configuration combines law enforcement and tactical user feedback into a purpose-built firearm suitable for home defense, specialized training, or experimental duty applications where conventional calibers present over-penetration concerns.
The DB165AL101 features a threaded 8-inch barrel finished in black nitride—a surface treatment that improves corrosion resistance, reduces glare, and extends barrel life in demanding conditions. The OD green aluminum Picatinny rail receiver pairs with a dedicated M-LOK handguard, allowing tactical accessory mounting while maintaining a compact overall length of 32 inches. A Magpul K grip provides enhanced ergonomics during precision shooting or close-quarters handling, while the 20+1 capacity accommodates standard 5.7x28mm magazines for mission flexibility. The combination of nitride finish and aluminum construction keeps the rifle at a practical 4.6 lbs, enabling sustained carry and rapid target transitions without fatigue.
This rifle benefits shooters evaluating specialized cartridges for precision or low-recoil applications, including competition shooters, designated marksmen requiring suppressed fire, and security professionals operating in noise-restricted environments. The threaded barrel accepts standard 5.7x28mm suppressors, delivering near-hearing-safe operation when paired with subsonic ammunition. The M-LOK rail system integrates seamlessly with modern tactical optics, lights, and vertical grips, while the modular design allows for future evolution as your mission requirements change. Ammunition compatibility is essential—operators should verify 5.7x28mm availability within their supply chain before deployment, as this cartridge requires dedicated sourcing distinct from mainstream rifle calibers.
