Wise Arms Wa-15b .300 Blackout 10.5" Rifle

The Wise Arms WA-15B 300BLK Gry 10.5" SBA3 is a purpose-built, short-barreled rifle designed for close-quarters operations, home defense, and specialized tactical applications. Built on a billet aluminum receiver and chambered in 300 AAC Blackout, this platform delivers the ballistic performance and modularity professionals demand in an ultra-compact form factor. The 10.5" barrel paired with the SBA3 stabilizing brace creates a highly maneuverable system that maintains effective downrange performance while remaining deployable in confined spaces—a critical advantage in breaching, vehicle operations, and dynamic entry scenarios.

The rifle features a billet aluminum receiver that ensures precision tolerances and durability under sustained use. The sniper grey Cerakote finish protects against corrosion and provides a professional aesthetic while reducing glint in operational environments. Chambered in 300 AAC Blackout, this cartridge delivers superior performance in subsonic ammunition applications—particularly valuable for suppressed operations where energy retention and terminal performance remain consistent. The 10.5" barrel optimizes muzzle velocity for both supersonic and subsonic loads while maintaining the compact profile essential for tactical flexibility. With a 30+1 round capacity using standard AR-platform magazines, the WA-15B provides adequate firepower for dynamic situations without adding excessive weight or length.

This configuration excels for operators, tactical professionals, and serious civilians seeking a suppressor-ready, close-quarters rifle platform. The SBA3 stabilizing brace accommodates various shooting positions while maintaining the compact profile. The 300 Blackout cartridge's inherent subsonic capability makes this rifle ideal for suppressed use without sacrificing terminal ballistics. Users can seamlessly integrate industry-standard AR-15 furniture, optics mounts, and accessories to customize the platform for specific missions. The lightweight design—approximately 5 lbs when equipped as configured—supports extended operations and rapid weapon manipulation in high-stress environments.
