Scope mount for henry big boy steel carbine - Henry Repeating Arms Co Weaver-Style Receiver Scope Mount For Henry Big Boy Rifles Gen2 BB-RSM

The mount fits perfectly to the top receiver of the Henry Big Boy steel carbine, making it very easy to install a red dot sight. The height of the mount, however, partially blocks the view of the barrel-mounted semi-buckhorn rear sight. My aging eyes were the reason to go with an optical sight in the first place, so losing the iron sights as a back-up is not a big loss. If I need a back-up, I'll just carry an extra red dot, pre sighted in.
