Shark Coast Tactical Viking Features The Shark Coast Tactical Viking runs a 16 inch black nitride treated barrel with a 1:7 twist rate giving it the stability to handle a wide range of 5.56 NATO bullet weights for range use or home defense. The direct impingement operating system delivers reliable cycling shooters expect from a proven AR-15 platform. A 1/2x28 threaded muzzle accepts a suppressor or muzzle device for those looking to manage recoil and sound signature.
