Wise Arms WA-15B | .300 AAC Blackout | 10.5in | SBA3

The Wise Arms WA-15B is a compact AR-style semi-automatic pistol chambered in .300 AAC Blackout with a 10.5-inch threaded barrel and an SBA3 pistol brace. It pairs a short, maneuverable profile with a billet aluminum receiver and a 7″ M-LOK handguard for accessory mounting. This configuration is well-suited to range training and short-range hunting or varmint work where a compact .300 BLK platform is desirable. For a reliable optic under $1,000, consider a Holosun HS510C red-dot for fast target acquisition on this platform.
