A BB gun is a type of air gun designed to shoot metallic spherical projectiles called BBs (not to be confused with similar-looking bearing balls), which are approximately the same size as BB-size lead birdshot used on shotguns (0.180 in or 4.6 mm in diameter). Modern BB guns normally have a smoothbore barrel with a iv.5 mm (0.177 in) quotient, and use steel assurance that measure 4.three–4.four mm (0.171–0.173 in) in diameter and 0.33–0.35 thou (5.1–5.iv gr) in weight, usually zinc- or copper-plated for corrosion resistance. Some manufacturers yet make the slightly larger traditional lead balls that weigh effectually 0.48–0.50 1000 (7.4–7.seven gr), which are generally intended for use in rifled barrels (due to pb having better malleability and exerting less wear on riflings).

The term "BB gun" is frequently used to describe airsoft guns, which shoot plastic pellets (also ofttimes incorrectly referred to equally "BBs") that are larger (commonly 6 mm or 0.24 in in diameter) simply much less dumbo than metal Bbs,^[1] and have significantly lower ballistic performance. The term is too sometimes used incorrectly to depict a pellet gun, which shoots diabolo-shaped (not spherical) lead projectiles at higher ability and velocity. Although some BB guns can likewise shoot pellets, the reverse situation is not truthful: steel BB assurance have greater stiffness and are not meant to be shot from pellet guns, whose barrels are typically rifled and thus can get stuck (similar to a squib load in firearms) and lead to a damage or mechanical failure inside the gun.

History [edit]

The term BB originated from the nomenclature of the size of lead shots used in a smoothbore shotgun. Size "BB" shots were ordinarily 0.180 in (4.half dozen mm), just tended to vary considerably in size due to the loose tolerances in shotshells. The highest size shotgun pellet commonly used was named 00 or double ought and was used for hunting deer and thus called buckshot, while the smaller BB-sized shot was typically used to shoot small/medium-sized game birds and therefore was a birdshot.

In 1886, the Markham Air Rifle Company in Plymouth, Michigan produced the outset wooden-construct spring-piston air burglarize design as a youth training gun, and used the BB-size birdshot as the called armament. Two years later, the neighbouring Plymouth Air Rifle Company (later renamed Daisy Manufacturing Company in 1895) introduced the showtime full-metal airgun that as well fired BB shots – the Daisy BB Gun, which became a very popular household proper name due to its successful marketing. Around 1900, Daisy changed their BB-size diameter diameter to 0.175 in (four.iv mm), and began to market place precision-made lead shot specifically for their BB guns. They called these "round shots", but the BB proper noun was already well established, and most users connected calling their guns BB guns, and the projectiles every bit BB shots or just Bulletin board system.

Afterward, the term BB became generic, and is used loosely referring to any small spherical projectiles of various calibers and materials. This includes bearing balls frequently utilized by anti-personnel mines, .177 quotient lead/steel shots used past air guns, plastic circular balls (such as the pellets used by airsoft guns), small marbles and many others. It has go ubiquitous to refer to whatsoever steel ball, such equally a BB, as a "brawl bearing". However, BBs should non be confused with a ball bearing, which is a mechanical component using small internal rolling balls to reduce friction between moving parts of machines.

Operation [edit]

BB guns can utilise any of the operating mechanisms used for air guns. However, due to the inherent limited accuracy and short effective range of the projectile, only the simpler and less expensive mechanisms are by and large used for guns designed to burn down only Bbs.^{[ commendation needed ]}

Because the strength of the steel BB does not allow it to exist swaged with the low propelling force used to accelerate information technology through the butt, BBs are slightly smaller (4.3 to 4.4 mm (0.171 to 0.173 in)) than the internal diameter of the barrel (4.v mm (0.177 in)). This limits accuracy because little spin is imparted on the BB. It too limits range, because some of the pressurized gas used to accelerate the BB leaks around it and reduces the overall efficiency. Since a BB will easily coil unhindered down the barrel, it is common to find guns that apply a magnet in the loading machinery to hold the BB at the rear of the barrel until it is fired.^{[ commendation needed ]}

The traditional and all the same about common powerplant for BB guns is the spring-piston pump, commonly patterned after a lever-action rifle or a pump-action shotgun. The lever-action rifle was the beginning type of BB gun, and still dominates the inexpensive youth BB gun market. The Daisy Model 25, modeled after a pump-action shotgun with a trombone pump-action mechanism, dominated the low-price, higher-performance market for over 50 years. Lever-action models mostly have very low velocities, around 84 thousand/s (275 ft/s), a result of the weak springs used to go along cocking efforts low for use by youths. The Daisy Model 25 typically achieved the highest velocities of its day, ranging from 114 to 145 m/south (375 to 475 ft/s).^[2]

Multiple-pump pneumatic guns are also common. Many pneumatic pellet guns provide the ability to apply BBs every bit a cheaper alternative to pb shot. Some of these guns have rifled barrels, but the slightly undersized Bbs do non swage in the barrel, so the rifling does not impart a significant spin. These are the types of guns that volition benefit most from using precision lead BB shot. The pneumatic BB gun can attain much higher velocities than the traditional spring piston types.^{[ citation needed ]}

The final common type of power for BB guns is compressed gas, almost commonly the Powerlet cartridges. The powerlet is a disposable metallic gas cylinder containing 12 grams (190 gr) of compressed carbon dioxide, with a self-contained valve to release the CO₂ which expands to propel the BB. These are primarily used in BB pistols, and are capable of rapid firing unlike spring-piston or pneumatic types. A typical CO₂ BB pistol uses a leap-loaded magazine to feed BBs, and a double-activeness trigger machinery to chamber a BB and cock the hammer. However some guns (either to stay true to the original gun or to make the trigger pull easier) exercise have a unmarried-activity trigger. Either type of gun may also have blowback action, where CO₂ will button the slide back in addition to firing a BB. When firing, the hammer strikes an internal valve linked to the CO₂ source, which releases a measured corporeality of CO_ii gas to fire the BB; this too gives information technology realistic recoil and muzzle study features. Many CO₂ BB guns are patterned later popular firearms such as the Colt M1911, and can be used for training as well every bit recreation.^{[ citation needed ]}

Some gas-powered BB guns use a larger source of gas, and provide machine gun-like fire. These types, virtually notably the Shooting star Tommy Gun (originally known as the Feltman) are commonly found at carnivals. The MacGlashan BB Gun was used to railroad train antiaircraft gunners in the The states Army Air Corps and The states Navy during World War II. A popular commercial model was the Larc M-xix, which used one pound (454 g) canisters of Freon-12 refrigerant. These types have very elementary operating mechanisms, based on a venturi pump. The gas is released in a constant stream, and this is used to suck the Bbs upward into the butt at rates as high as 3600 rounds per minute.^[iii]

Condom [edit]

BB guns can shoot faster than threescore m/south (200 ft/s), but are ofttimes less powerful than a conventional pellet airgun. Pellet airguns accept the ability to fire considerably faster, fifty-fifty beyond 170 m/s (560 ft/south).^[4] ^[5] ^[half-dozen] Although claims are often exaggerated, a few airguns can actually burn down a standard 0.177 caliber lead pellet faster than 320 g/south (i,000 ft/s), just these are generally non BB-firing guns.

A BB with a velocity of 45 thou/s (150 ft/s) has peel-piercing capability, and a velocity reaching 60 m/s (200 ft/s) can fracture bone.^[7] This is potentially lethal, and this potential increases with velocity, but besides rapidly decreases with altitude. The constructive penetrating range of a BB gun with a cage velocity of 120 to 180 m/due south (390 to 590 ft/s) is approximately 18 m (60 ft). A person wearing jeans at this distance would not sustain serious injury. However, even at this distance a BB still might penetrate bare skin, and even if not, could leave a severe and painful bruise. The maximum range of a BB gun in the 120 to 180 m/s (390 to 590 ft/s) range is 220 to 330 yard (240 to 360 yd), provided the muzzle is elevated to the optimum angle.

Steel Bulletin board system are too notably decumbent to ricochet off hard surfaces such as brick, concrete, metal, or wood finish grain. Eye protection is essential when shooting BBs at these materials, more than and so than when shooting lead pellets, since a BB bouncing off a hard surface can retain a big portion of its initial energy (pellets usually flatten and blot free energy), and could easily cause serious eye damage.^{[ commendation needed ]}

Quick Kill training [edit]

The U.Due south. Regular army trained recruits in Quick Kill techniques using Daisy Model 99 BB guns to meliorate soldiers using their weapons in the Vietnam War from 1967 to 1973. The technique was developed for the Regular army past Bobby Lamar "Lucky" McDaniel and Mike Jennings.^[8]
