Takedown is as simple as locking the bolt back and verifying that the rifle is unloaded, pushing a recessed lever, twisting the subassemblies and pulling them apart. Dead blow action features a custom tungsten dead blow weight that shortens bolt travel and reduces felt recoil and muzzle rise. Bolt is machined from heat treated, chrome-moly steel to ensure strength, structural integrity and durability.
