A rifle is a long-barreled firearm designed for accurate shooting and higher stopping power, with a barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles have been used in warfare, law enforcement, hunting and target shooting sports.
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.
A magazine, often simply called a mag, is an ammunition storage and feeding device for a repeating firearm, either integral within the gun or externally attached. The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a "clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine or cylinder.
The ArmaLite AR-15 is a gas-operated assault rifle manufactured in the United States between 1959 and 1964. Designed by American gun manufacturer ArmaLite in 1956, it was based on its AR-10 rifle. The ArmaLite AR-15 was designed to be a lightweight rifle and to fire a new high-velocity, lightweight, small-caliber cartridge to allow infantrymen to carry more ammunition.
The Beta C-Mag is a 100-round capacity drum magazine manufactured by the Beta Company. It was designed by Jim Sullivan and first patented in 1987 and has been adapted for use in numerous firearms firing the 5.56×45mm NATO, 7.62×51mm NATO, and 9×19mm Parabellum cartridges. C-Mag is short for century magazine, referring to its 100-round capacity. It has two drum units, each of which hold half of the cartridges inserted into the magazine. The latest version of the magazine is available with a transparent backing to allow the user to see the number of rounds remaining in the magazine. A C-Mag loaded with 5.56×45mm NATO ammunition typically weighs about 2.1 kg (4.63 lb); a C-Mag loaded with 7.62×51mm NATO ammunition weighs 4.77 kg (10.5 lb).
The two most common assault rifles in the world are the Soviet AK-47 and the American M16. These Cold War-era rifles have been used in conflicts both large and small since the 1960s. They are used by military, police, security forces, revolutionaries, terrorists, criminals, and civilians alike and will most likely continue to be used for decades to come. As a result, they have been the subject of countless comparisons and endless debate.
The 6.5mm Grendel is an intermediate cartridge jointly designed by British-American armorer Bill Alexander, competitive shooter Arne Brennan and Lapua ballistician Janne Pohjoispää, as a low-recoil, high-precision rifle cartridge specifically for the AR-15 platform at medium/long range. It is an improved variation of the 6.5mm PPC.
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.
Stratasys, Ltd. is an American-Israeli manufacturer of 3D printers, software, and materials for polymer additive manufacturing as well as 3D-printed parts on-demand. The company is incorporated in Israel. Engineers use Stratasys systems to model complex geometries in a wide range of polymer materials, including: ABS, polyphenylsulfone (PPSF), polycarbonate (PC) and polyetherimide and Nylon 12.
The .300 AAC Blackout, also known as 7.62×35 mm, is an intermediate cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. The cartridge yields increased performance in shorter barrels and effective subsonic performance for silencer use when compared to 5.56 mm NATO. The .300 AAC Blackout uses standard 5.56 mm NATO magazines and components with the exception of the barrel.
Defense Distributed is an online, open-source hardware and software organization that develops digital schematics of firearms in CAD files, or "wiki weapons", that may be downloaded from the Internet and used in 3D printing or CNC milling applications. Among the organization's goals is to develop and freely publish firearms-related design schematics that can be downloaded and reproduced by anyone with a 3D printer or milling machine, facilitating the popular production of homemade firearms.
Cody Rutledge Wilson is an American gun rights activist and crypto-anarchist. He started Defense Distributed, a non-profit organization which develops and publishes open source gun designs, so-called "wiki weapons" created by 3D printing and digital manufacture. He is the director of Defense Distributed; it gained international notoriety in 2013 when it published plans online for the Liberator, the first widely available functioning 3D-printed pistol.
A 3D-printed firearm is a firearm that is partially or primarily produced with a 3D printer. While plastic printed firearms are associated with improvised firearms, or the politics of gun control, digitally-produced metal firearms are more associated with commercial manufacturing or experiments in traditional firearms design.
The G22 Grizzly is a series of 3D-printed, single-shot, break-action rifles that fire .22LR cartridges. Initially developed in 2013 by a Canadian designer known by the pseudonym "Matthew", the G22 Grizzly has evolved through multiple iterations, with each version improving design, functionality, and printability. It is known for its high level of 3D-printability, requiring minimal non-printable metal parts. The latest version, G22v4, was released in September 2023.
The Feinstein AK Mag is a 3D printed magazine for the AK-47 rifle. It was created by Defense Distributed and made public in March 2013. The magazine was created using a Stratasys Dimension SST 3-D printer via the fused deposition modeling (FDM) method.
The AR Lower V5 is a 3D printed lower receiver for the AR-15 rifle. It was created in March 2013 Defense Distributed printed using the Stratasys Dimension SST 3-D printer using the fused deposition modeling (FDM) method.
The 3DX, also known as the Auxetik, was the first 3D printed metal muzzle brake and the first 3D printed metallic component for a firearm. It is meant for the highly customisable AR-15 rifle. The design was made public around July 2013. The printer used to print it is unknown but the brake was created using the Direct metal laser sintering (DMLS) method by Sintercore. It is designed to tame the recoil and muzzle rise of AR-15 pistols chambered for .223 caliber (5.56×45mm) NATO rounds. The Auxetik was renamed to 3DX by Sintercore.
The Hanuman AR-15 Bullpup which was made public in May 2014 is a prototype AR-15 rifle Bullpup created by WarFairy
Come and Take It: The Gun Printer's Guide to Thinking Free is an autobiographical book written by American gun rights activist, author and crypto-anarchist, Cody Wilson in 2016.
