Ranger Point Henry Big Boy RHINO 1913 Scope Mount

Ranger Point Precision's RHINO rail is the scope-mounting answer for the pistol-caliber Henry Big Boy, and its defining trait is how low it sits. At 0.28 inches of rail height over a 5.5-inch receiver-flush length, it keeps a red dot or scout scope close to the bore so your cheek weld stays natural and the optic clears the factory irons on most setups.

It is a precision-machined steel 1913 mil-spec rail, so it indexes correctly with any standard Picatinny ring and holds zero under magnum recoil. The kit includes three 8-40 screws, the heavier fastener size that belongs on a hard-recoiling lever gun rather than the 6-48 screws found on lighter mounts.

Fitment is specific: this rail is cut for Henry Big Boy steel receivers in .357, .41, .44 magnum, and .45 Colt. It does not fit brass receivers, the Costa rail system, or the large-frame .45-70, .30-30, .38-55, and .410 receivers, and it requires Picatinny rings rather than Weaver-spec.
