To optimize accuracy and to keep the beauty of their receivers intact, Henry Cantilever Scope Mounts are mounted to the barrel. Golden Boys and Big Boys now come pre-drilled and tapped. You simply tap out the rear sight and it will reveal two holes that are drilled and tapped for easy screw in scope mount installation. The Henry Cantilever Scope Mounts accepts Weaver type detachable 1″ top mount rings (Not Included).

Note to Big Boy Owners (H006/H012 Series)

Previous production from pre-2011 (or 1st Generation) Brass Big Boy rifles were drilled and tapped on the barrel under the rear sight, they were NOT drilled/tapped on the receiver. You will need to use this (BB-CSM) for 1st Generation H006 Brass Big Boy series.
