The Reprringer is a 3D printed pepperbox firearm, [1] [2] [3] [4] made public around September 2013. [2] It is a 5-shot, single-action, manually-indexed .22 CB Cap revolver. [2] [3]
Unlike the many early 3D-printed firearm designs, which are usually massively overbuilt in order to withstand the pressures and strain on the material from modern gunpowder cartridges, the Reprringer is small and only slightly larger than a gun made from steel. [2] It is chambered for .22 CB Cap which is considered the least powerful commercially produced cartridge on the market. [2] The barrels are not rifled, the lack of theoretical accuracy is considered a non-issue in a small gun with no sights. [2]
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries.
A revolver is a repeating handgun with at least one barrel and a revolving cylinder containing multiple chambers for firing. Because most revolver models hold up to six cartridges, before needing to be reloaded, revolvers are commonly called six shooters or sixguns. Due to their rotating cylinder mechanism, they may also be called wheel guns.
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile, a propellant substance and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile.
In firearms terminology and at law, the firearm frame or receiver is the part of a firearm which integrates other components by providing housing for internal action components such as the hammer, bolt or breechblock, firing pin and extractor, and has threaded interfaces for externally attaching ("receiving") components such as the barrel, stock, trigger mechanism and iron/optical sights. Some firearm designs, such as the AR-15 platform, feature receivers that have 2 separate sub-assemblies called the upper receiver which houses the barrel/trunnion, bolt components etc and the lower receiver that holds the fire control group, pistol grip, selector, stock etc.
The pepper-box revolver or simply pepperbox is a multiple-barrel firearm, mostly in the form of a handgun, that has three or more gun barrels in a revolving mechanism. Each barrel holds a single shot, and the shooter can manually rotate the whole barrel assembly to sequentially index each barrel into alignment with the lock or hammer, similar to rotation of a revolver's cylinder.
A rim-fire is a type of metallic cartridge used in firearms where the primer is located within a hollow circumferential rim protruding from the base of its casing. When fired, the gun's firing pin will strike and crush the rim against the edge of the barrel breech, sparking the primer compound within the rim, and in turn ignite the propellant within the case. Invented in 1845 by Louis-Nicolas Flobert, the first rimfire metallic cartridge was the .22 BB Cap cartridge, which consisted of a percussion cap with a bullet attached to the top. While many other different cartridge priming methods have been tried since the early 19th century, such as teat-fire and pinfire, only small caliber rimfire cartridges have survived to the present day with regular use. The .22 Long Rifle rimfire cartridge, introduced in 1887, is by far the most common ammunition found in the world today in terms of units manufactured and sold.
A breechloader is a firearm in which the user loads the ammunition from the breech end of the barrel, as opposed to a muzzleloader, in which the user loads the ammunition from the (muzzle) end of the barrel.
The .22 long rifle, also known as the .22 LR or 5.7×15mmR, is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of firearms including rifles, pistols, revolvers, and submachine guns.
Ethan Allen was a major American arms maker from Massachusetts. He is unrelated to the revolutionary Ethan Allen. His first firearm, the "Pocket rifle" was developed in 1836, and his first patent was granted in 1837.
The .22 CB Cap, also known as the 6mm Flobert, is a more powerful version of the .22 BB Cap rimfire metallic cartridge, which was invented by Louis-Nicolas Flobert in 1845. The .22 BB Cap and .22 CB Cap are interchangeable and are relatively quiet, low velocity cartridges, designed for indoor target shooting.
A pistol sword is a sword with a pistol or revolver attached, usually alongside the blade. It differs from a rifle with a bayonet attached, in that the weapon is designed primarily for use as a sword, and the firearm component is typically considered a secondary weapon designed to be an addition to the blade, rather than the sword being a secondary addition to the pistol. In addition, the two components of these weapons typically cannot be separated, unlike most bayonets mounted on rifles.
Improvised firearms are firearms manufactured by an entity other than a registered firearms manufacturer or a gunsmith. Improvised firearms are typically constructed by adapting existing materials to the purpose. They range in quality, from crude weapons that are as much a danger to the user as the target, to high-quality arms produced by cottage industries using salvaged and repurposed materials.
An antique firearm is a term used to describe a firearm that was designed and manufactured prior to the beginning of the 20th century. Although the exact definition of what constitutes an "antique firearm" varies between countries, the advent of smokeless powder or the start of the Boer War are often used as cut-off dates. Antique firearms are usually collected because of their historical interest and/or their monetary value.
A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long barreled gun which typically is intended to be held by both hands and braced against the shoulder. Handguns have shorter effective ranges compared to long guns, and are much harder to shoot accurately. While most early handguns are single-shot pistols, the two most common types of handguns used in modern times are revolvers and semi-automatic pistols.
A multiple-barrel firearm is any type of firearm with more than one gun barrel, usually to increase the rate of fire or hit probability and to reduce barrel erosion or overheating.
A gallery gun, Flobert gun, parlor gun or saloon gun is a type of firearm designed for recreational indoor target shooting. These guns were developed in 1845, when French inventor Louis-Nicolas Flobert created the first rimfire metallic cartridge by modifying a percussion cap to hold a small lead bullet. In the 19th century, gallery guns were typically pump-action rifles chambered in .22 Short. Gallery guns are still manufactured, although by the late 20th century, they have been eclipsed by airguns for the purpose of indoor shooting.
The Liberator is a 3D-printable single-shot handgun, the first such printable firearm design made widely available online. The open source firm Defense Distributed designed the gun and released the plans on the Internet on May 6, 2013. The plans were downloaded over 100,000 times in the two days before the United States Department of State demanded that Defense Distributed retract the plans.
The Zig Zag revolver is a 3D-printed .38-caliber pepperbox type revolver made public in May 2014. It was created using a $500 plastic 3D-printer, however the name of the printer was not revealed by the creator.
Louis-Nicolas Flobert (1819–1894) was a French inventor. He invented the first metallic rimfire cartridge in 1845. It was a major innovation in firearms ammunition technology, as it was previously delivered as separate bullets and gunpowder, pertaining to muzzle-loading firearms. The rimfire cartridge combined both elements in a single metallic cartridge containing a percussion cap, gunpowder, and a bullet, into a single weatherproofed package or container. Before that, a "cartridge" was simply a pre-measured quantity of gunpowder together with a ball (bullet), in a small cloth bag, which also acted as wadding for the powder charge and ball.
