The Henry Gen 2 Big Boy Weaver-Style Receiver Scope Mount (brand part number BBRSM) is a black gloss aluminum alloy base built by Henry Repeating Arms for second-generation Big Boy lever rifles. Henry designs this one-piece base for easy installation, drilling and tapping it directly to the receiver and including instructions in the box so the process is straightforward even for a first-time install. It accepts Weaver-style detachable 1-inch top mount rings, which are not included, giving owners the flexibility to choose their own ring height and finish. Like Henry’s Picatinny-style Big Boy mount, it will not fit Big Boy models chambered in .45-70 or .30-30, but it’s correct for .44 Magnum, .45 Colt, .357 Magnum, .41 Magnum, and .327 Federal Magnum second-generation Big Boys.
