Wise Arms WA-15B Features The Wise Arms WA-15B is built on a billet aluminum receiver set giving the rifle a precisely machined foundation that holds tight tolerances between the upper and lower. Chambered in .300 AAC Blackout the platform takes advantage of this cartridge s flexibility cycling reliably with both subsonic loads favored for suppressed use and full power supersonic ammunition for longer range work. A 16 inch barrel with a 1 in 8 twist rate stabilizes the range of bullet weights commonly loaded in .300 BLK from light fast projectiles to heavy subsonic rounds. The threaded 5/8x24 muzzle accepts suppressors and muzzle devices directly making this rifle a natural fit for shooters who want to run the cartridge suppressed. A 6 position collapsible A2 stock lets the shooter adjust overall length from 32 to 35 inches dialing in the right length of pull for different body types or armor and clothing setups. The rifle s semi-auto action feeds from a 30 round magazine giving a substantial on-board capacity for range sessions or defensive use. A 2 position thumb safety offers straightforward familiar manual of arms for anyone experienced with AR pattern rifles. Finished in a distinctive Sniper Grey Cerakote applied finish and shipped in a canvas carry bag the Wise Arms WA-15B at 6.45 pounds combines a practical .300 Blackout platform with a finish that sets it apart from standard black rifles.
