Lower Receiver
In firearms terminology, 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. The receiver is often made of forged, machined, or stamped steel or aluminium; in addition to these traditional materials, modern science and engineering have introduced polymers and sintered metal powders to receiver construction. Mounting A barrel can be fixed to the receiver using barrel and receiver action threads or similar methods. In US law For the purposes of United States law, the receiver or frame is legally the firearm, and as such it is the controlled part. The definition of which assembly is the legal receiver varies from firearm to firearm, under US law. Generally, the law require ...

AR-15
An AR-15-style rifle is any lightweight semi-automatic rifle based on the Colt AR-15 design. The original ArmaLite AR-15 is a scaled-down derivative of Eugene Stoner's ArmaLite AR-10 design. The then Fairchild Engine and Airplane Corporation division ArmaLite sold the patent and trademarks to Colt's Manufacturing Company in 1959. After most of Colt's patents for the Colt AR-15 expired in 1977, many firearm manufacturers began to produce copies of the Colt AR-15 under various names. While the patents are expired, Colt retained the trademark of the AR-15 and is the sole manufacturer able to label their firearms as ''AR-15''. The "AR" in Colt AR-15 stands for "ArmaLite Rifle", not " assault rifle". The Federal Assault Weapons Ban restricted the sale of the Colt AR-15 and some derivatives in the United States from 1994 to 2004, although it did not affect rifles with fewer listed features. After the term modern sporting rifles was coined in 2009 by the US National Shooting Sports F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TechCrunch
TechCrunch is an American online newspaper focusing on high tech and startup companies. It was founded in June 2005 by Archimedes Ventures, led by partners Michael Arrington and Keith Teare.

Defense Distributed
Defense Distributed is an online open-source hardware 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 ghost guns. The company is best known for developing and releasing the files for the Liberator, the world's first completely 3D printed gun. On May 5, 2013, Defense Distributed made these printable STL files public, and within days the United States Department of State demanded they be removed from the Internet, citing a violation of the International Traffic in Arms Regulations. On May 6, 2015, Defense Distributed, joined by the Second Amendment Foundation (SAF), filed '' Defense Distributed v. U.S. Dept. of State'' in th ...

Stratasys
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. Stratasys manufactures in-office prototyping and direct digital manufacturing systems for automotive, aerospace, industrial, recreational, electronic, medical and consumer product OEMs. History Stratasys was founded in 1989, by S. Scott Crump and his wife Lisa Crump in Eden Prairie, Minnesota. The idea for the technology came to Crump in 1988 when he decided to make a toy frog for his young daughter using a glue gun loaded with a mixture of polyethylene and candle wax. He thought of creating the shape layer by layer and of a way to automate the process. In April 1992, Stratasys sold it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fused Deposition Modeling
Fused filament fabrication (FFF), also known as fused deposition modeling (with the trademarked acronym FDM), or called ''filament freeform fabrication'', is a 3D printing process that uses a continuous filament of a thermoplastic material. Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the growing work. The print head is moved under computer control to define the printed shape. Usually the head moves in two dimensions to deposit one horizontal plane, or layer, at a time; the work or the print head is then moved vertically by a small amount to begin a new layer. The speed of the extruder head may also be controlled to stop and start deposition and form an interrupted plane without stringing or dribbling between sections. "Fused filament fabrication" was coined by the members of the RepRap project to give an acronym (FFF) that would be legally unconstrained in its use. Fused filament printing is now the most popular process ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3D Printed Firearms
A 3D printed firearm is a firearm that is primarily produced with a 3D printer. They can be classified by the type of 3D printers used: plastic (desktop fused filament fabrication), metal (industrial selective laser melting), or both. While plastic ones are usually used as improvised firearms that evade gun control, 3D-printed metal guns are more commonly thought as a way for legitimate gun manufacturers to exceed traditional design limitations.New Zealand leads the way in Titanium Additive Manufacturing Metal Additive Manufacturing, May 12, 2014.

Firearm Components
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber (i.e. b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ArmaLite AR-10 Derivatives
ArmaLite, or Armalite, is an American small arms engineering company, formed in the early 1950s, in Hollywood, California. Many of its products, as conceived by chief designer Eugene Stoner, relied on unique foam-filled fiberglass butt/stock furniture, and a composite barrel using a steel liner inside an aluminum sleeve, including the iconic AR15/M16 family. While the original ArmaLite ceased business in the 1980s, the brand was revived in 1996, by Mark Westrom. Originating as the light firearms division of Fairchild Engine and Airplane Corporation, ArmaLite was formally incorporated in 1954. Stoner's first design, the AR-1 Parasniper (dating from 1952), was relatively unsuccessful. However, in 1956, when ArmaLite competed in a contest for an aircrew survival rifle, its AR-5 and AR-7 designs were put into production and adopted by elements of the US military. The following year, ArmaLite also competed for the contract for a new main US combat rifle, in the NATO standard 7.62 mm ...
