Wise Arms WA-15B | .300 AAC Blackout | 7.5″ SBA3

The Wise Arms WA-15B is a compact AR-style semi-automatic configured for .300 AAC Blackout with a short 7.5-inch barrel and an SBA3 pistol brace. It pairs a billet aluminum receiver with a white Cerakote finish for a distinctive look while maintaining corrosion resistance. For a practical optic choice under $1,000 that complements the platform, consider a Trijicon MRO or a Holosun HS503CU red-dot for quick target acquisition and robust performance.

Typical applications include close-range target shooting and suppressed small-game or varmint outings where the .300 AAC Blackout cartridge and threaded barrel are advantageous. The pistol-length profile supports maneuverability in tight spaces and quick handling on short courses.
