Breechblock
A breechblock (or breech block) is the part of the firearm action that closes the breech of a breech loading weapon (whether small arms or artillery) before or at the moment of firing. It seals the breech and contains the pressure generated by the ignited propellant. Retracting the breechblock allows the chamber to be loaded with a cartridge. Breechblocks are categorised by the type or design of the mechanism by which it is locked or closed for firing. The firearm action more fully refers to the mechanism by which the operator actuates the opening and closing of the breech. Variants A way of closing the breech or chamber is an essential part of any breech-loading weapon or firearm. Perhaps the simplest way of achieving this is a break-action, in which the barrel, forestock and breech pivot on a hinge that joins the front assembly to the rear of the firearm, incorporating the rear of the breech, the butt and usually, the trigger mechanism. A breechblock is a separate compone ...

This may refer to: * A semi-automatic firearm, a firearm which automatically loads the next round, but will only fire one round per trigger pull ** Semi-automatic rifle ** Semi-automatic pistol ** Semi-automatic shotgun * Semiautomatic switching system, a term used in telecommunication * Semi-automatic transmission: a manual transmission with an automated clutch (i.e., no physical clutch pedal), but the driver is still required to shift gears manually, by hand.

Firearm Malfunction
A firearm malfunction is the failure of a firearm to operate as intended for causes other than user error. Malfunctions range from temporary and relatively safe situations, such as a casing that did not eject, to potentially dangerous occurrences that may permanently damage the gun and cause injury or death. Improper handling of certain types of malfunctions can be very dangerous. Following gun safety rules can prevent firearm malfunctions, and limit the damage inflicted by them if they do occur. Many versions of safety rules exist, but all of them tend to lean toward universal principles. Proper cleaning and maintenance of a firearm play a big role in preventing malfunctions. Cartridge malfunctions Case head separation Case head separation occurs when the walls of the casing become thin or fatigued. Upon firing the round, the case separates into two pieces near the head. It is not uncommon with brass (or other casing types) that has been reloaded several times. Misfire A ...

Field Strip
Field stripping is firearms terminology for the act of disassembling a firearm to the greatest possible extent without the usage of any extra tools. A disassembly that uses such tools is called a detail strip, but this is less common than a field strip, as the latter is usually sufficient for most cases. Definition Field strips are done to facilitate cleaning, or identify damages. It is customary for soldiers to be taught how to conduct a field strip, both as a means of discipline, and to help create a sense of familiarity with the weapon. Because it is an integral part of owning and using a firearm, especially in a military context, firearm manufacturers will take considerations to make field strips expedient and simple. In one instance, the Los Angeles Police Department opted against the purchase of Thompson submachine guns The Thompson submachine gun (also known as the "Tommy Gun", "Chicago Typewriter", "Chicago Piano", “Trench Sweeper” or "Trench Broom") is a blow ...

American Rifleman
''American Rifleman'' is a United States-based monthly shooting and firearms interest publication, owned by the National Rifle Association (NRA). It is the 33rd-most-widely-distributed consumer magazine and the NRA's primary magazine. The magazine has its headquarters in Fairfax, Virginia. History Arthur Corbin Gould, an avid shooter and member of the Massachusetts Rifle Association, published ''The Rifle'' in 1885 as an effort to focus discussion on the sport of rifle shooting. ''The Rifle'' later changed its title to ''Shooting and Fishing'' in 1888, branching out into other outdoor sports. In 1894, while the magazine was titled ''Shooting and Fishing'', Gould attended the National Rifle Association matches held at Sea Girt and was impressed with the level of competition, leading him to write several editorials urging the public to join. This call eventually led to the revitalization of the National Rifle Association and established a Board of Directors to help manage the ...

Recoil (magazine)
''Recoil'' is a magazine covering handguns, tactical rifles, tactical knives and other shooting-related activities in the United States. It caters to the firearms lifestyle. The magazine primarily offers reviews on firearms, ammunition, knives, and shooting gear; as well as gunsmithing tips, historical articles, gun collecting, self-defense and automobiles.

Point Shooting
Point shooting, also known as target- or threat-focused shooting, intuitive shooting, instinctive shooting or subconscious tactical shooting, is a practical shooting method where the shooter points a ranged weapon (typically a revolver or semiautomatic pistol) at a target without relying on the use of sights to aim. Emphasis is placed on fast draw and trying to score preemptive hits first. In close quarters combat, where life-threatening situations emerge very quickly, sighted marksmanship techniques become risky, so advocates of point shooting emphasize a less sighting-oriented style that prioritizes the tactical advantages of quick fire superiority and suppression. Point shooting is also a technique used by trained archers and marksmen to improve general accuracy when using a bow, crossbow, firearm or other ranged weapon. By developing a muscle memory for a given weapon, the shooter can become so accustomed to the weapon's weight and balance in its typical shooting position a ...

45 ACP
The .45 ACP (Automatic Colt Pistol) or .45 Auto (11.43×23mm) is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide that a minimum of .45 caliber was required in a new handgun. The standard issue military .45 ACP round uses a 230-grain (14.9 g) round nose projectile that travels at approximately 830 feet per second (250 m/s) when fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating of , compared to for both 9mm Parab ...

Recoil
Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases (ejectae) will be mathematically balanced out by an equal and opposite momentum exerted back upon the gun. In hand-held small arms, the recoil momentum will be eventually transferred to the ground, but will do so through the body of the shooter hence resulting in a noticeable impulse commonly referred to as a "kick". In heavier mounted guns, such as heavy machine guns or artillery pieces, recoil momentum is transferred to the Earth's surface through the platform on which the weapon is mounted. In order to bring the rearward moving gun to a halt, the momentum acquired by the gun is di ...

John Pedersen (arms Designer)
John Douglas Pedersen (May 21, 1881 – May 23, 1951) was a prolific arms designer who worked for Remington Arms, and later for the United States Government. Famed gun designer John Moses Browning told Maj. Gen. Julian S. Hatcher of U.S. Army Ordnance that Pedersen "was the greatest gun designer in the world". Early career Pedersen is best known for the 1918 Pedersen device that converted a standard military Springfield 1903 rifle to a semi-automatic, pistol-caliber firearm. He designed several successful sporting guns for Remington, including the novel Model 51 pistol, the Model 10 pump-action shotgun and the Models 12, 14, and 25 pump-action rifles. He collaborated with John Browning to design the Model 17 pump-action shotgun. The Model 17 was a trim, 20-gauge shotgun that was later redesigned and made in three highly successful forms: the Remington Model 31, Browning BPS, and the Ithaca 37. Pedersen designed two well received U.S. military firearms from the 20th centur ...
