About the Remington

The company was founded in 1816 when Eliphalet Remington II handcrafted his first rifle in his father’s forge and with the help of a local gunsmith managed to turn it into a simple flintlock rifle for his personal use. Taking second place in a shooting contest, Remington's rifle attracted a great amount of attention and shortly after, first orders started to come in.

The production line was moved to the Erie Canal which is nowadays known as the present location of the Remington factory in Ilion, New York. Early on, the company manufactured around 5000 pieces of M1841 Mississippi rifles to be used in the U.S. army additionally receiving a large government order of 1000 Jenks loading carbines. A few years after establishing its first armoury in 1848, three of the founder's sons joined the company and renamed it, E. Remington & Sons. The following years brought the outbreak of the Civil War in 1861 and at that point the company was supplying the Federal Army and Navy with arms such as pistols, carbines, rifles, and muskets, increasing their production rate significantly. Eliphalet Remington passed away in the same year, leaving the business up to his three sons. The army-oriented production shifted in direction again at the end of the War in 1865 when the company started to fabricate different firearms for civilian hunting and shooting sports. In 1871, the company established its ammunition production under the name Remington Ammunition Works. They were producing centrefire ammunition for pistols, shotguns, and rifles. Two years later, after gaining the trust of inventors Christopher Sholes and Carlos Glidden, the company even managed to produce its first fully functional typewriter in Ilion, New York.

In the following years, the company presented some of its early weapon models such as the first American autoloader (later known as M11), Model 8, and Model 10. At the beginning of World War I, Remington enlarged their facilities, expanding out to four locations, increasing arms and ammunition production rate once again. Signal guns, autoloading pistols such as Model 51, rifles and machine guns were swiftly being produced in great numbers. In addition, they entered a cutlery business during the war period, producing roughly 2.500.000 knives annually by the year 1926. Remington was revolutionizing its products every step of the way. Being the first to introduce the concept of game load ammunition, they took over the shotshell industry by storm. Ammunition production increased again in World War II when the company expanded its production to 7 more locations. Some of the most recognizable weapon models were presented during this period such as Model 03A4 or M1903A3 Springfield which was a renewed and simplified version of 1903 Springfield.

In the years after the war, they released the Model 870 'Wingmaster’ shotgun which became the world’s bestseller at that point, Nylon 66 autoloading .22 rifle, Model 700 bolt-action rifle, Model 1100 and an M24 sniper rifle that was regularly used as a standardized US army sniper rifle until 2010. Meanwhile, they also managed to stay operative in the knife making business. Ten years after building a new ammunition plant in Lonoke, Ark., DuPont purchased the remaining Remington shares and became the majority owner of the company, however, they later sold the assets to RACI Acquisitions in New York. In 2011 they re-focused on the production of handguns, launching the R1 1911 semi-automatic pistol. Another renowned weapon, namely the Model 783 bolt-action rifle was released two years later, in 2013.

Today, Remington is known as the oldest gun manufacturer in America, celebrating a more than 200-year-old history of diligence and quality.

Remington 521 Rifle Review

Remington 521, otherwise known as Junior Special is a bolt-action repeating rifle manufactured from 1947 until 1968 that is based on the design of Remington 513 but is resized for younger audiences. It features a six-round capacity detachable box magazine, a heavy steel receiver that houses dual locking lugs, and an encased bolt head which allows for extra safety and accuracy. The rifle does not come with pre-drilled holes on the receiver; hence they must be manually drilled by a gunsmith.

The trigger is pre-set at the factory and a streamlined self-cocking bolt with a low upturn of the bolt handle is case hardened for extra strength. There is a lever thumb safety placed on the side of the receiver that blocks the trigger and engages automatically whenever the rifle is cocked. A red dot firing pin indicator showing when the weapon is cocked is placed behind the safety lever. In addition, Remington 521 comes with a match target stock, a semi-floating barrel and included target sights.

Possible barrel length for Remington is 635 mm (25-light) and 686 mm (27-inch).
