To optimize accuracy, Henry Scope Mounts are available for all Henry Big Boy models.

Each of these rifles now come drilled and tapped for easy scope mount installation. Henry H001 series lever action rifles do not require use of these mounts as the receivers have a 3/8th inch groove to accommodate scope rings.

The Golden Boy and 1st generation Big Boy rifles are drilled and tapped under the rear sight. Current production (2nd generation) Big Boys are drilled and tapped on the top of the receiver. To determine which generation of Big Boy you have refer to the serial number. Instructions on installation of the scope mounts is provided in the packaging.

All Henry Scope Mounts accept Weaver style detachable 1" top mount rings (rings not included). 

These bases will not fit Henry .30/30 or Henry .45-70 rifles as they are not Big Boy Series (pistol caliber: .44mag,.45Colt,.357mag,.41mag,.327Fed Mag) guns. 

Note to Big Boy owners
In September 2011 Henry began shipping the 2nd generation Big Boy rifles which feature receivers that are drilled and tapped for the scope mount. In previous production 1st generation the barrels were drilled and tapped if rollmarked Bayonne NJ. First generation Big Boys use the BB-CSM Cantilever Scope Mount. 2nd generation current production use the new style BB-RSM Receiver Scope Mount.
