Our Assessment: From SKB’s 1981 catalog: “Built to take the punishment of repeated, heavy shooting. A new, angled wood-to-metal union at the stock soaks up more of the true recoil without extra strain on the stock. Other features include automatic selective ejectors, New, enlarged locking lug on the barrel holds barrel and frame tightly together even after years of heavy shooting. Mechanical trigger means the second shot is quickly there if you need it. Other eye-catching features are semi-beavertail forend, accented by hand-checered, non-slip design. Wide raised ribs: 16mm wide rib on trap model.” This shotgun has clearly not seen much shooting, much less years of heavy shooting. It is a gorgeous shotgun and with the legendary SKB name, it probably shoots as well as it looks. It is an easy gun to shoulder and comes right up with your head down on the stock. From the engraving to the beautiful stock to the very solid lockup, everything about this shotgun screams quality. Whether you’re rounding out an SKB collection or if you just want to have the prettiest gun on the range, this is a fantastic shotgun to bid on. Please see our photos and good luck!
