Controlled Round Feed
Push feed and controlled feed (or controlled round feed) are two main types of mechanisms used in firearms to describe how the bolt drives the cartridge into the chamber and extracts the spent casing after firing. * The push feed system does not grip the base of the cartridge before the cartridge has been fully entered into the chamber, and therefore under normal operation requires the cartridge to be fully chambered before it can be extracted. * The controlled feed system grips the base of the cartridge with the extractor claw before the cartridge is stripped from the magazine, and therefore makes it possible to extract the cartridge before it has been fully chambered. The better of the two systems has been debated for over 50 years, and both systems have their strengths and weaknesses. Some prefer the controlled round feed for hunting on dangerous game, while others state that either of the systems can be reliable or unreliable, depending for example on the quality of the r ...

Winchester Model 70
The Winchester Model 70 is a bolt-action sporting rifle. It has an iconic place in American sporting culture and has been held in high regard by shooters since it was introduced in 1936, earning the moniker "The Rifleman's Rifle". The action has some design similarities to Mauser designs and it is a development of the earlier Winchester Model 54, itself based on a Mauser 98-type action. The Model 70 was originally manufactured by the Winchester Repeating Arms Company between 1936 and 1980. From the early 1980s until 2006, Winchester rifles were manufactured by U.S. Repeating Arms under an agreement with Olin Corporation, allowing USRA to use the Winchester name and logo. Model 70s were built in New Haven, Connecticut, from 1936 to 2006, when production ceased. In the fall of 2007, the Belgian company FN Herstal announced that Model 70 production would resume. As of 2012, new Winchester Model 70 rifles were being made by FN Herstal in Columbia, South Carolina. In 2013, assembly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MG 42
The MG 42 (shortened from German: ''Maschinengewehr 42'', or "machine gun 42") is a German recoil-operated air-cooled general-purpose machine gun used extensively by the Wehrmacht and the Waffen-SS during the second half of World War II. Entering production in 1942, it was intended to supplement and replace the earlier MG 34, which was more expensive and took much longer to produce, but both weapons were produced until the end of World War II. Designed to use the standard German 7.92×57mm Mauser rifle round, be low-cost and easier to mass-produce, the MG 42 proved to be highly reliable and easy to operate. It is most notable for its very high cyclic rate for a gun using full-power service cartridges, averaging about 1,200 rounds per minute compared to around 850 for the MG 34, and 450 to 600 for other common machine guns like the M1919 Browning, FM 24/29 or Bren gun. This ability made it extremely effective in providing suppressive fire, and its unique sound led to it bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Belt-fed systems minimize the proportional weight of the ammunition apparatus to the entire weapon system, and allow high rates of continuous fire without needing frequent magazine changes. The capacity of belts and associated belt containers is typically a function of weight and bulk, and their size is limited by caliber and the combined portability of the weapon and ammunition. The most common ammo capacity typically carried on a man-portable weapon system vary from 50 to 300 rounds. Variants Feed strip 8mm Lebel feed strip on an M1914 H ...

Pawl
A pawl is a movable lever that engages a fixed component to either prevent movement in one direction or restrain it altogether. As such, it is a type of latch and can also be considered a type of dog. It typically consists of a spring-loaded lever that engages a mating component at a steep enough angle to restrain it. Pawls are often tapered, being widened at their pivot for anchoring and narrow at their tip. Applications ;Anchor windlass: A pawl is used in an anchor windlass to prevent a free-spooling chain by grabbing and snubbing an individual link. Similar mechanisms include a Devil's claw, or a claw and dog. ;Ratchet: A pawl is used in combination with a ratchet gear in socket wrenches, bicycle freehubs, winches, and many other applications. ;Ladder: Dogs (in the form of pawls) are used on extension ladders to temporarily anchor their sections to one-another. ;Table saw: Pawls are used on table saws to prevent a workpiece being sawn from kicking back. ;Transmissi ...

Ruger American Rifle
The Ruger American Rifle is a family of budget-level hunting/ sporting bolt-action centerfire rifle made by Sturm, Ruger & Co., which also produces a line of rimfire rifles with similar designs called the Ruger American Rimfire. Design The Ruger American has a receiver made from 4140 chrome-moly bar stock and a hammer-forged barrel with a blued black oxide finish, mounted onto a polymer composite stock. Some models are also available in a stainless steel variant. Rather than using a traditional recoil lug, the rifle's barreled action is secured in the stock by a bedding system known as "Power Bedding®", which uses two V-shaped steel action blocks that wedge the receiver firmly in place to prevent lateral shifts and also serve as recoil lugs. Because the front and back action screws are fastened through the centers of the action blocks, the blocks also functionally act as pillar beddings and allows the barrel to be free-floated. The rifle feeds cartridges into the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sako 75

Remington Model 700
The Remington Model 700 is a series of bolt-action centerfire rifles manufactured by Remington Arms since 1962. It is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948. The M24 and M40 military sniper rifles, used by the US Army and Marine Corps, respectively, are both based on the Model 700 design. The Remington 700 series rifles often come with a 3-, 4- or 5-round internal magazine depending on the caliber chambered, some of which have a hinged floor-plate for quick unloading, and some of which are "blind" (with no floor-plate).

Colt AR-15
The Colt AR-15 is a lightweight, magazine-fed, gas-operated semi-automatic rifle. It is a semi-automatic version of the M16 rifle sold for the civilian and law enforcement markets in the United States. Colt's Manufacturing Company currently owns the ''AR-15'' trademark, which is used exclusively for its line of semi-automatic AR-15 rifles. History Due to financial problems, and limitations in terms of manpower and production capacity, ArmaLite sold the AR-15 design and the AR-15 trademark along with the ArmaLite AR-10 to Colt's Manufacturing Company in 1959. Colt started selling the semi-automatic version of the M16 rifle as the Colt AR-15 in 1964. The first mass production version was the Colt AR-15 Sporter, in .223 Remington, with a 20-inch barrel, issued with 5-round magazines. Colt has since made many different models of AR-15 rifle and carbine models, including the AR-15, AR-15A2, AR-15A3, AR-15A4, and others. Sale of new AR-15s in the USA was banned by the Feder ...

Weatherby Mark V
The Weatherby Mark V is a centerfire, bolt-action rifle manufactured by Weatherby of Sheridan, Wyoming. The rifle was introduced in 1957 by Weatherby and was designed to safely contain the high pressures associated with the Weatherby line of high performance cartridges. It is the flagship rifle of the Weatherby line of firearms. The Weatherby Mark V rifles are considered prestigious or luxury firearms by many. This is due in part to Roy Weatherby who presented the rifles to royalty, politicians, gun writers and actors including Prince Abdorreza Pahlavi of Iran, Generals James Doolittle (USAF) and Chuck Yeager (USAF), Jack O'Connor, Warren Page, Elgin Gates and Lorne Greene and was able to use this fact as a marketing tool. Early development Ever since Roy Weatherby began manufacturing rifles he had to rely on a third party to provide the actions for his rifles. Beginning in 1949 Weatherby began building his rifles around the FN Belgian Mauser action. In 1955 Schultz & Larson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
