EM-4 Rifle
The EM-4 rifle (Burney rifle) was an experimental bullpup rifle of British origin designed by Sir Dennis Burney of the Broadway Trust Company. Overview The principle of the Burney was an enlarged chamber that the gases expanded into and were then exhausted through the barrel using a type of high–low system The high–low system (or high–low pressure system, high–low propulsion system, high–low projection system) is a design of cannon and anti-tank warfare launcher using a smaller high-pressure chamber to store propellant. It allows a much large .... The Burney 7mm rifle, usually referred to as the Broadway Trust Rifle, may have been referred to as the Experimental Model EM-4. The rifle was under trial in 1946-1947 but failed to show sufficient promise and was abandoned in March 1948. Design The action is short recoil, and is as follows: 1. When loaded the barrel is held to the rear by the trigger sear, against the force of the barrel spring, with the round chambere ...

Dennis Burney
Sir Charles Dennistoun Burney, 2nd Baronet (28 December 1888 – 11 November 1968, in Bermuda) was an English aeronautical engineer, private inventor and Conservative Party politician.''Oxford Dictionary of National Biography'' Oxford: OUP. Early military career Burney, often called Dennis Burney, was the son of Admiral of the Fleet Sir Cecil Burney Bt. (Dennis Burney succeeded to the Baronetcy when his father died in 1929.) His sister was Sybil Katherine Neville-Rolfe. He was given a naval education, starting his training at HMS ''Britannia'' in 1903, and joining the battleship ''Exmouth'' as a midshipman in early 1905. He was posted to the destroyer HMS ''Crusader'' in 1909, which was being used for experimental anti-submarine work at the time. In 1911, he came up with a novel seaplane design using a hydrofoil undercarriage. Further development was carried out by the Bristol and Colonial Aeroplane Company and two prototype designs, the X.2 and X.3, were produced, ...

Bullpup
A bullpup firearm is one with its firing grip located in front of the breech of the weapon, instead of behind it. This creates a weapon with a shorter overall length for a given barrel length, and one that is often lighter, more compact, concealable and more maneuverable than a conventionally configured firearm. Where it is desirable for troops to be issued a more compact weapon, the use of a bullpup configuration allows for barrel length to be retained, thus preserving muzzle velocity, range and ballistic effectiveness. The bullpup concept was first tested militarily in 1901 with the British Thorneycroft carbine, but it was not until the Cold War that more successful designs and improvements led to wider adoption. In 1977, the Austrian Army became the first military force in the world to adopt a bullpup rifle, the Steyr AUG, as a principal combat weapon. Since then the militaries in many countries have followed suit with other bullpup designs, such as the Chinese QBZ-95, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifle
A rifle is a long-barreled firearm designed for accurate shooting, with a barrel that has a helical 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 are used extensively in warfare, law enforcement, hunting, shooting sports, and crime. The term was originally ''rifled gun'', with the verb ''rifle'' referring to the early modern machining process of creating groovings with cutting tools. By the 20th century, the weapon had become so common that the modern noun ''rifle'' is now often used for any long-shaped handheld ranged weapon designed for well-aimed discharge activated by a trigger (e.g., personnel halting and stimulation response rifle, which is actually a laser dazzler). Like all typical firearms, a rifle's projectile ( bullet) is propelled by the contained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Barrel
A gun barrel is a crucial part of gun-type weapons such as small arms, small firearms, artillery pieces, and air guns. It is the straight shooting tube, usually made of rigid high-strength metal, through which a contained rapid expansion of high-pressure gas(es) is used to propel a projectile out of the front end (muzzle (firearms), muzzle) at a high velocity. The hollow interior of the barrel is called the bore, and the diameter of the bore is called its caliber, usually measured in inches or millimetres. The first firearms were made at a time when metallurgy was not advanced enough to cast tubes capable of withstanding the explosive forces of early cannons, so the pipe (often built from staves of metal) needed to be braced periodically along its length for structural reinforcement, producing an appearance somewhat reminiscent of storage barrels being stacked together, hence the English name.''A History of Warfare'' - John Keegan, Keegan, John, Vintage 1993.

High–low System
The high–low system (or high–low pressure system, high–low propulsion system, high–low projection system) is a design of cannon and anti-tank warfare launcher using a smaller high-pressure chamber to store propellant. It allows a much larger projectile to be launched without the heavy equipment usually needed for large caliber weapons. When the propellant is ignited, the higher pressure gases are bled out through vents (or ports) at reduced pressure to a much larger low pressure chamber to push a projectile forward. The high-low system allows the weight of the weapon and its ammunition to be reduced significantly. Production cost and time are drastically lower than for standard cannon or other small-arm weapon systems firing a projectile of the same size and weight. It has a far more efficient use of the propellant, unlike earlier recoilless weapons, where most of the propellant is expended to the rear of the weapon to counter the recoil of the projectile being fired.

Assault Rifles Of The United Kingdom
An assault is the act of committing physical harm or unwanted physical contact upon a person or, in some specific legal definitions, a threat or attempt to commit such an action. It is both a crime and a tort and, therefore, may result in criminal prosecution, civil liability, or both. Generally, the common law definition is the same in criminal and tort law. Traditionally, common law legal systems have separate definitions for assault and battery. When this distinction is observed, battery refers to the actual bodily contact, whereas assault refers to a credible threat or attempt to cause battery. Some jurisdictions combined the two offences into a single crime called "assault and battery", which then became widely referred to as "assault". The result is that in many of these jurisdictions, assault has taken on a definition that is more in line with the traditional definition of battery. The legal systems of civil law and Scots law have never distinguished assault from battery ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trial And Research Firearms Of The United Kingdom
In law, a trial is a coming together of Party (law), parties to a :wikt:dispute, dispute, to present information (in the form of evidence (law), evidence) in a tribunal, a formal setting with the authority to Adjudication, adjudicate claims or disputes. One form of tribunal is a court. The tribunal, which may occur before a judge, jury, or other designated trier of fact, aims to achieve a resolution to their dispute. Types by finder of fact Where the trial is held before a group of members of the community, it is called a jury trial. Where the trial is held solely before a judge, it is called a bench trial. Hearing (law), Hearings before administrative body, administrative bodies may have many of the features of a trial before a court, but are typically not referred to as trials. An appeal (appellate proceeding) is also generally not deemed a trial, because such proceedings are usually restricted to a review of the evidence presented before the trial court, and do not permit the ...
