Henry Big Boy Silver American Walnut Lever Action Rifle – 45 (Long) Colt – 20in – The Henry Big Boy Silver model is an equally striking throwback to the days of nickel plating on prized guns to protect and enhance their visual appeal. Its frame is constructed of a solid aluminum-bronze alloy that’s actually slightly tougher than the long-running hardened brass alloy in the popular brass-framed. Other features included buckhorn/bead sights, straight stock wrist, carbine-style buttplate, ten-round magazine capacity, tube magazine loading, an transfer bar safety.
