The Remington Model 11 is a licensed production of the John Browning-designed Auto-5 shotgun. First produced in 1906, it was the first mechanically reliable and commercially successful semi-automatic shotgun produced. It is available in 12-, 16- and 20-gauge varieties.
Among the most prolific American gun designers, John Browning had attempted to sell his Auto-5 design to the Winchester company. When Winchester rejected the idea, Browning offered the plans to Remington, but negotiations collapsed with the unexpected death of the company president. A Belgian firm produced the gun for several years before Remington was able to secure domestic rights to the weapon. Production was eventually discontinued in 1947 with a total of 850,000 manufactured.
