Henry Single Shot Blued/Walnut Single Shot Rifle - 450 Bushmaster - The centerfire single-shot rifle features a matte finish with a steel frame. It also features a round barrel, with adjustable buckhorn and brass bead sights and is drilled/tapped for optional scope use. The stock is constructed of walnut, with a curved pistol grip wrist and solid rubber recoil pad. The action has no external manual safety; it uses a rebounding hammer that can't touch the firing pin unless the trigger's deliberately pulled, and an interlock system that doesn't allow the barrel to open if the hammer's cocked, or the barrel to close if the hammer's cocked while it's open.
