{"product_id":"mossberg-500b-16ga","title":"Mossberg 500B 16ga","description":"\u003cp\u003eThe Mossberg 500B is a 16-gauge variant of the iconic Mossberg 500 pump-action shotgun series. The standard Mossberg 500 was introduced in 1961 (initially in 12 gauge), with 16-gauge versions added in 1963. The \"B\" designation specifically refers to the 16-gauge model in early production nomenclature.\u003c\/p\u003e\n\u003cp\u003eProduction of the 500B (16 gauge) ran from around 1963 into the late 1960s (some sources cite up to 1969), though it was relatively short-lived and is now considered somewhat rare compared to the more common 12-gauge models. The overall Mossberg 500 line has been in continuous production since 1961, with over 11 million units made across variants, but the dedicated 16-gauge 500B was discontinued early on.\u003c\/p\u003e\n\u003cp\u003eMossberg serial numbers for the 500 series are typically a letter prefix followed by 5-6 digits (e.g., letter + numbers).\u003c\/p\u003e\n\u003cp\u003eThe \"B\" prefix aligns with the model designation (500B for 16 gauge), and this format was used on some early serialized examples.\u003c\/p\u003e\n\u003cp\u003eFederal law (Gun Control Act of 1968) did not require serial numbers on long guns like shotguns until 1968. Many pre-1968 Mossberg 500s (including 500B models) have no serial number at all, or very low\/simple ones if present.\u003c\/p\u003e\n\u003cp\u003eMaking this 500B a 1968-1969 manufactured Mossberg. \u003c\/p\u003e\n\u003cp\u003eShips Free to the FFL of your choice!\u003c\/p\u003e","brand":"Whiskey Rebellion Antiques","offers":[{"title":"Default Title","offer_id":42668148490317,"sku":null,"price":550.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0610\/9229\/8829\/files\/rn-image_picker_lib_temp_e4acd673-2304-4e7a-a029-f64793428a3e.jpg?v=1770836844","url":"https:\/\/whiskeyrebellionantiques.com\/products\/mossberg-500b-16ga","provider":"Whiskey Rebellion Antiques","version":"1.0","type":"link"}
