M6 Aircrew Survival Weapon
The M6 Aircrew Survival Weapon was a specially-made .22 Hornet over .410 bore combination gun issued to United States Air Force aircrews to help forage for food in the event of a plane crash. It was issued from 1952 until the early 1970s, in conjunction with the M4 Survival Rifle. Plans to replace both with the ArmaLite AR-5 (aka: MA-1) never came to fruition and in 2018 was instead replaced with the GAU-5A Aircrew Self Defense Weapon in some instances. History The M6 was originally developed in 1946 for the Air Materiel Command of what was then still the United States Army Air Forces by the United States Army Ordnance Corps. Its official designation was ''Rifle-Shotgun, Survival, Caliber .22/.410''. It was designed to fit into the standard USAAF (later USAF) survival kit issued to all pilots flying over Arctic and other uninhabited regions. Design The M6 is made of stamped sheet steel, with a forged steel removable barrel assembly. The barrel assembly is connected to the sto ...

Combination Gun
A combination gun is a firearm that usually comprises at least one rifled barrel and one smoothbore barrel, that is typically used with shot or some types of shotgun slug. Most have been break-action guns, although there have been other designs as well. Combination guns using one rifled and one smoothbore barrel are commonly found in an over-and-under configuration, while the side-by-side configuration is usually referred to as a cape gun. A combination gun with more than two barrels are called a (German for "triplet") with three barrels, a (German for "quadruplet") with four barrels, and a (German for "quintuplet") with five barrels. Combination guns generally use rimmed cartridges, as rimless cartridges are more difficult to extract from a break-action firearm. Use Combination guns have a long history in Europe, Middle East, Asia, and Africa that date back to the early days of cartridge firearms. These guns are almost exclusively hunting arms. The advantage of having a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pound (mass)
The pound or pound-mass is a unit of mass used in British imperial and United States customary systems of measurement. Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly , and which is divided into 16 avoirdupois ounces. The international standard symbol for the avoirdupois pound is lb; an alternative symbol is lbm (for most pound definitions), # ( chiefly in the U.S.), and or ″̶ (specifically for the apothecaries' pound). The unit is descended from the Roman (hence the abbreviation "lb"). The English word ''pound'' is cognate with, among others, German , Dutch , and Swedish . These units are historic and are no longer used (replaced by the metric system). Usage of the unqualified term ''pound'' reflects the historical conflation of mass and weight. This accounts for the modern distinguishing terms ''pound-mass'' and '' pound-force''. Etymology The word 'pound' and its cognates ultim ...

Caliber Conversion Sleeve
A caliber conversion sleeve or adapter sleeve is a device which can be used to non-permanently alter a firearm to allow it to fire a different cartridge than the one it was originally designed to fire. The different cartridge must be smaller in some dimensions than the original design cartridge, and since smaller cartridges are usually cheaper, the device allows less expensive fire practice. Alternative names sometimes imply the type of dimensional difference. A chamber insert may be used for a shorter cartridge of similar base diameter. A supplemental chamber or cartridge adapter is typically used for a shorter cartridge of reduced diameter. A cartridge conversion sleeve may include a short barrel of reduced bore diameter. Shotgun conversion sleeves may be called subgauge inserts, subgauge tubes, or gauge reducers. Sleeves intended for rifle or handgun cartridges may have rifled barrels. Additional variations may allow centerfire weapons to fire rimfire ammunition and/or re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
20 Gauge
The 20-gauge shotgun, also known as "20-bore", is a type of smooth-bore shotgun that fires a shell that is smaller in caliber () than a 12-gauge shotgun (). It is often used by beginning shooters for target practice and for hunting small game. Description It takes 20 lead balls of the diameter of a 20-gauge shotgun bore to equal one pound, while it only takes 12 lead balls of the diameter of a 12-gauge shotgun bore to equal the same weight. A 20-gauge shotgun is more suitable for hunting certain types of game or for some hunters because it recoils less, and the guns weigh less and may be smaller. Regarding the yellow body tube color 20-gauge ammunition usually has, it has been reserved in SAAMI documentation saying "SAAMI has reserved yellow for 20-gauge ammunition" "This ammunition shall have a body tube that is primarily yellow" "Yellow shall not be used for any other gauge/bore shotshell body" "No other recommendations are made as to the color of service body tubes for other g ...

12 Gauge Shotgun
The gauge (or commonly bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) of the barrel. Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the sphere's weight as a fraction of a pound, e.g., a one-twelfth pound lead ball fits a 12-gauge bore. Thus there are twelve 12-gauge balls per pound, etc. The term is related to the measurement of cannon, which were also measured by the weight of their iron round shot; an 8-pounder would fire an 8 lb (3.6 kg) ball. Gauge is commonly used today in reference to shotguns, though historically it was also used in large double rifles, which were made in sizes up to 2 bore during their heyday in the 1880s, being originally loaded with black powder cartridges. These very large rifles, called "elephant guns", were intended for use primarily in Africa and Asia for hunting lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Picatinny Rails
The Picatinny rail ( or ), or Pic rail for short, also known as a MIL-STD-1913 rail, 1913 rail or STANAG 2324 rail (cancelled), is a military standard rail interface system that provides a mounting platform for firearm accessories. It was originally used for mounting of scopes atop the receivers of larger caliber rifles. Once established, its use expanded to also attaching other accessories, such as: iron sights, tactical lights, laser aiming modules, night vision devices, reflex sights, holographic sights, foregrips, bipods, slings and bayonets. An updated version of the rail is adopted as a NATO standard as the STANAG 4694 NATO Accessory Rail. Significance Because of their many uses, Picatinny rails and accessories have replaced iron sights in the design of many firearms and available as aftermarket add-on parts for most actions that do not have them integrated, and they are also on the undersides of semi-automatic pistol frames and grips. When adding a Picat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Firearms Act
The National Firearms Act (NFA), 73rd Congress, Sess. 2, ch. 757, was enacted on June 26, 1934, and currently codified and amended as . The law is an Act of Congress in the United States that, in general, imposes an excise tax on the manufacture and transfer of certain firearms and mandates the registration of those firearms. The NFA is also referred to as Title II of the federal firearms laws, with the Gun Control Act of 1968 ("GCA") as Title I. All transfers of ownership of registered NFA firearms must be done through the National Firearms Registration and Transfer Record (the "NFA registry"). The NFA also requires that the permanent transport of NFA firearms across state lines by the owner must be reported to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Temporary transports of some items, most notably suppressors (also referred to as silencers), do not need to be reported.

22 Long Rifle
The .22 Long Rifle or simply .22 LR or 22 (metric designation: 5.6×15mmR) is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of rifles, pistols, revolvers, smoothbore shotguns, and submachine guns. In terms of units sold it is by far the most common ammunition in the world today. Common uses include hunting and shooting sports. Ammunition produced in .22 Long Rifle is effective at short ranges, has little recoil, and is cheap to purchase, making it ideal for training. History American firearms manufacturer J. Stevens Arms & Tool Company introduced the .22 Long Rifle cartridge in 1887. The round owes its origin to the .22 BB Cap of 1845 and the .22 Short of 1857. It combined the case of the .22 Long of 1871 with a bullet, giving it a longer overall length, a higher muzzle velocity and superior performance as a hunting and target round, rendering the .22 Extra Long cartridges obsolete.
