Wise Arms WA-15B Features The Wise Arms WA-15B is chambered in .300 AAC Blackout and built on a billet aluminum receiver for a rigid precisely machined platform. The 10.5 inch barrel carries a 1 in 8 twist rate which stabilizes the heavier bullet weights commonly used in subsonic .300 Blackout loads while still handling lighter supersonic ammunition. A threaded muzzle with a 1/2x28 thread pattern accepts a wide range of aftermarket muzzle devices or suppressors. The overall length adjusts from 26.5 to 30.5 inches giving the shooter a range of brace positions to suit different shooting stances. Finished entirely in Flat Dark Earth Cerakote the WA-15B presents a durable corrosion resistant exterior that also resists fading from sun exposure during field use. The pistol ships with a single 30 round magazine for a 30 plus 1 capacity and a 2 position thumb safety provides straightforward intuitive manual control. At 9.6 pounds unloaded the WA-15B carries the heft of a solidly built AR pistol while remaining maneuverable in tighter spaces than a full length rifle. A canvas carry bag is included for transport and storage giving shooters and .300 Blackout enthusiasts a complete ready to run pistol package.
