Colt Advanced Piston Carbine
The Colt Advanced Piston Carbine or Colt APC is a lightweight modular 5.56mm caliber piston-operated, magazine fed carbine with a one-piece upper receiver which is capable of firing in automatic and semi-automatic modes. The design incorporates an articulating link piston that reduces the stresses in the piston stroke by allowing for deflection and thermal expansion. Design The weapon has a suppression-ready fluted barrel, which is lighter and cools better than previous M4 barrels. It is claimed to have "markedly better" accuracy. To improve reliability, Colt used an articulating link piston (ALP) which "reduces the inherent stress in the piston stroke by allowing for deflection and thermal expansion". In traditional gas piston operating systems, the force of the piston striking the bolt carrier can push the bolt carrier downwards and into the wall of the buffer tube, leading to accelerated wear and even chipped metal. This is known as carrier tilt. The ALP (articulating li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-automatic Firearm
A semi-automatic firearm, also called a self-loading or autoloading firearm (fully automatic and selective fire firearms are also variations on self-loading firearms), is a repeating firearm whose action mechanism ''automatically'' loads a following round of cartridge into the chamber (self-loading) and prepares it for subsequent firing, but requires the shooter to ''manually'' actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot (in the form of recoil or high-pressure gas expanding within the bore) to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, eac ...

Carbines
A carbine ( or ) is a long gun that has a barrel shortened from its original length. Most modern carbines are rifles that are compact versions of a longer rifle or are rifles chambered for less powerful cartridges. The smaller size and lighter weight of carbines make them easier to handle. They are typically issued to high-mobility troops such as special operations soldiers and paratroopers, as well as to mounted, artillery, logistics, or other non-infantry personnel whose roles do not require full-sized rifles, although there is a growing tendency for carbines to be issued to front-line soldiers to offset the increasing weight of other issued equipment. An example of this is the U.S. Army's M4 carbine, which is standard issue. Etymology The name comes from its first users — cavalry troopers called "carabiniers", from the French ''carabine'', from Old French ''carabin'' (soldier armed with a musket), whose origin is unclear. One theory connects it to an "ancient engine of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Response Team
An incident response team (IRT) or emergency response team (ERT) is a group of people who prepare for and respond to an emergency, such as a natural disaster or an interruption of business operations. Incident response teams are common in public service organizations as well as in other organizations, either military or specialty. This team is generally composed of specific members designated before an incident occurs, although under certain circumstances the team may be an ad hoc group of willing volunteers. Incident response team members ideally are trained and prepared to fulfill the roles required by the specific situation (for example, to serve as incident commander in the event of a large-scale public emergency). As the size of an incident grows, and as more resources are drawn into the event, the command of the situation may shift through several phases. In a small-scale event, usually only a volunteer or ad hoc team may respond. In events, both large and small, both specifi ...

Police Coast Guard Special Task Squadron
The police are a constituted body of persons empowered by a state, with the aim to enforce the law, to ensure the safety, health and possessions of citizens, and to prevent crime and civil disorder. Their lawful powers include arrest and the use of force legitimized by the state via the monopoly on violence. The term is most commonly associated with the police forces of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. Police forces are often defined as being separate from the military and other organizations involved in the defense of the state against foreign aggressors; however, gendarmerie are military units charged with civil policing. Police forces are usually public sector services, funded through taxes. Law enforcement is only part of policing activity. Policing has included an array of activities in different situations, but the predominant ones are concerned with the pre ...

Singapore Police Force
The Singapore Police Force (SPF) is the national and principal law enforcement agency responsible for the prevention of crime and law enforcement in the Republic of Singapore. It is the country's lead agency against organised crime; human, weapon trafficking; cyber crime; as well as economic crime that goes across domestic and international borders, but can be tasked to investigate any crime under the purview of the Ministry of Home Affairs (MHA) and is accountable to the Parliament of Singapore. SPF's main geographical area of responsibilities covers the entire country, consisting of five regions which are further divided into 55 planning areas. The organisation has various staff departments with specific focuses. These include the Airport Police Division (APD), which covers policing of Singapore's main civilian airports of Changi and Seletar, or the Police Coast Guard (PCG), which protects and enforces areas under Singapore's territorial waters and its ports.

VAT 69 Commando
The 69 Commando (, Jawi: ٦٩ كومندو); also known as Very Able Troopers 69 (abbreviation: VAT 69) is an elite multi-tasking special forces unit of the Royal Malaysia Police. The VAT 69 is based at Ulu Kinta, Perak and together with Special Actions Unit ( ms, Unit Tindakhas; UTK), they are part of ''Pasukan Gerakan Khas'' (abbreviated ''PGK'', ). The mission of 69 Commando is to conduct high-risk tasks such as counter-terrorism, hostage rescue, intelligence gathering and counter-insurgency within the borders of Malaysia. Prior to 1989, the 69 Commando was primarily tasked with the war against communist terrorists in the Malaysian jungle. Today, 69 Commando has much wider counter-terrorism and counter-insurgency role, but it still maintains considerable expertise in jungle warfare; many of their operators are drawn from the Senoi Praaq, an elite tracking unit which is now part of RMP's General Operations Force.

Carrier Tilt
Carrier tilt is a wear issue that can arise in some gas piston-based firearm operating systems. High pressure gas pushes the gas piston back hitting the bolt carrier. This force pushes the bolt carrier down into the buffer tube wall. This can lead to increased wear, shaved and/or chipped metal. This in turn can lead to a loss of accuracy.

Other companies solve this issue modifying the carrier length. Black Rifle Arms utilizing a short ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas-operated Reloading
Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action. History The first mention of using a gas piston in a single-shot breech-loading rifle comes from 1856, by the German Edward Lindner who patented his invention in the United States and Britain. In 1866, Englishman William Curtis filed the first patent on a gas-operated repeating rifle, but subsequently failed to develop that idea further. Between 18 ...
