Oscar Mossberg developed an early reputation as a designer and inventor for the Iver Johnson, Marlin-Rockwell, Stevens, and Shattuck Arms companies. In 1915, he began producing a 4-shot, .22 LR cal. palm pistol known as the "Novelty," with revolving firing pin. After producing approx. 600 of these pistols, he sold the patent to C.S. Shattuck, which continued to manufacture guns under the name "Unique." The first 600 had no markings except serial numbers, and were destined for export to South America. Very few of these original "Novelty" pistols survived in this country, and they are extremely rare specimens.
Mossberg acquired Advanced Ordnance Corp. during 1996, a high quality manufacturer utilizing state-of-the-art CNC machinery.
Current manufacturer of rifles, shotguns, pistols, and AR-15 style firearms, located in North Haven, CT, 1962-present and New Haven, CT, 1919-1962.
