The "Royal Small Arms Factory" was a British government-owned rifle factory that was in operation between the 19th and 20th centuries. Over the years, it was known by a number of different names, including the Enfield Lock Armory, Enfield Arsenal, and simply the Royal Arms Factory. Despite the numerous name changes, the factory was well-known for producing high-quality weapons, particularly during World War II. Its iconic Lee-Enfield rifles were used by British forces throughout the war, making it a crucial part of the country's military history. Today, the factory is no longer in operation, but its legacy lives on in the many firearms it produced.
