Up for auction is a factory-original, OEM Mossberg 930 12-Gauge semi-automatic shotgun barrel. This is the highly sought-after 18.5-inch home defense and tactical roit/police length barrel featuring a standard brass front bead sight and a fixed cylinder bore. It is the perfect upgrade for anyone looking to convert a long-barrel 930 hunting or sporting shotgun into a compact, highly maneuverable defensive setup, or for anyone simply needing a reliable factory replacement. Because Mossberg has shifted its primary production focus toward the newer 940 platform, standalone factory 930 defensive barrels like this one are increasingly difficult to find in stock at major retail distributors, making this a great opportunity to pick up an authentic factory part.
This OEM barrel is explicitly designed for the 12-gauge Mossberg 930 series and features a 3-inch chamber, allowing it to safely handle and cycle both 2.75-inch and 3-inch shells. The fixed cylinder bore muzzle is the ideal restriction for home defense applications, performing beautifully with standard buckshot, specialized defensive loads, and rifled slugs. It features a non-reflective, factory matte-blued finish that matches standard tactical and home security receivers perfectly.
In terms of condition, this barrel is in very good, pre-owned shape. The internal bore is bright, smooth, and mirror-clean. The exterior finish looks great but does exhibit normal handling marks and light cosmetic wear from regular use, including typical light thinning around the magazine tube ring and under the forend where the components interface during normal semi-auto cycling. All mounting surfaces, threads, and alignment lugs remain perfectly crisp and structurally sound, ensuring it drops cleanly onto your receiver without issue. Please review the high-resolution photos carefully to see the exact cosmetic condition of the finish.
