The Henry Gen 2 Big Boy Picatinny Receiver Scope Mount (brand part number BBRSMP) is a black matte aluminum base built by Henry Repeating Arms specifically for second-generation Big Boy lever rifles. Henry cuts this base to the Picatinny rail standard and drills and taps it directly to the receiver, giving second-generation Big Boy owners a factory-matched way to add a modern optic. It’s built for the H006, H006M, and H006C models starting at their second-generation serial number ranges, and it will not fit Big Boy models chambered in .45-70 or .30-30. For owners running .44 Magnum, .45 Colt, .357 Magnum, .41 Magnum, or .327 Federal Magnum Big Boys, it’s the correct factory-style optics platform.
