The MSR 15 Valkyrie gets maximum performance from the 224 Valkyrie cartridge, which was developed to deliver supersonic velocities past 1,300 yards, extremely flat trajectories and match accuracy. The competition-ready MSR 15 Valkyrie gets the most from the cartridge’s unprecedented capabilities with an upgraded 18-inch barrel with 5R rifling and a crisp two-stage trigger. Its Elite Series FDE Cerakote finish forms a tough, protective layer on the upper and lower, and its adjustable mid-length gas system can be customized to specific ammunition for the most reliable cycling.
