A BB gun is a type of air gun designed to shoot metallic spherical projectiles called BBs (not to be dislocated with similar-looking bearing balls), which are approximately the same size as BB-size lead birdshot used on shotguns (0.180 in or 4.half-dozen mm in bore). Modern BB guns ordinarily have a smoothbore barrel with a 4.5 mm (0.177 in) caliber, and utilize steel balls that measure iv.3–4.4 mm (0.171–0.173 in) in diameter and 0.33–0.35 g (5.1–5.4 gr) in weight, usually zinc- or copper-plated for corrosion resistance. Some manufacturers still make the slightly larger traditional pb balls that counterbalance around 0.48–0.50 grand (7.iv–vii.vii gr), which are generally intended for use in rifled barrels (due to lead having meliorate malleability and exerting less wear on riflings).

The term "BB gun" is frequently used to draw airsoft guns, which shoot plastic pellets (as well oftentimes incorrectly referred to as "Bulletin board system") that are larger (commonly 6 mm or 0.24 in in diameter) but much less dense than metal BBs,^[1] and have significantly lower ballistic performance. The term is too sometimes used incorrectly to describe a pellet gun, which shoots diabolo-shaped (not spherical) lead projectiles at higher power and velocity. Although some BB guns tin also shoot pellets, the reverse situation is not true: steel BB balls have greater stiffness and are not meant to exist 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 impairment or mechanical failure within the gun.

History [edit]

The term BB originated from the nomenclature of the size of pb shots used in a smoothbore shotgun. Size "BB" shots were commonly 0.180 in (4.6 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 pocket-size/medium-sized game birds and therefore was a birdshot.

In 1886, the Markham Air Burglarize Company in Plymouth, Michigan produced the start wooden-construct bound-piston air rifle design as a youth training gun, and used the BB-size birdshot as the called ammunition. Two years later, the neighbouring Plymouth Air Rifle Visitor (afterward renamed Daisy Manufacturing Company in 1895) introduced the start total-metal airgun that too fired BB shots – the Daisy BB Gun, which became a very popular household name due to its successful marketing. Effectually 1900, Daisy changed their BB-size bore bore to 0.175 in (4.4 mm), and began to market precision-fabricated lead shot specifically for their BB guns. They chosen these "round shots", but the BB proper name was already well established, and nearly users connected calling their guns BB guns, and the projectiles as BB shots or just Bbs.

Subsequently, the term BB became generic, and is used loosely referring to whatsoever small spherical projectiles of various calibers and materials. This includes bearing balls oft utilized past anti-personnel mines, .177 caliber lead/steel shots used by air guns, plastic round balls (such as the pellets used by airsoft guns), pocket-sized marbles and many others. It has become ubiquitous to refer to any steel brawl, such as a BB, as a "ball bearing". However, BBs should not be dislocated with a ball bearing, which is a mechanical component using pocket-sized internal rolling balls to reduce friction betwixt moving parts of machines.

Operation [edit]

BB guns can use whatever of the operating mechanisms used for air guns. However, due to the inherent limited accuracy and brusk effective range of the projectile, only the simpler and less expensive mechanisms are generally used for guns designed to fire simply Bbs.^{[ citation needed ]}

Considering the strength of the steel BB does not allow it to exist swaged with the low propelling strength used to accelerate it through the barrel, Bbs are slightly smaller (four.3 to 4.4 mm (0.171 to 0.173 in)) than the internal diameter of the barrel (4.5 mm (0.177 in)). This limits accuracy considering little spin is imparted on the BB. Information technology also limits range, considering some of the pressurized gas used to accelerate the BB leaks around information technology and reduces the overall efficiency. Since a BB will hands roll unhindered down the butt, it is mutual to find guns that employ a magnet in the loading mechanism to hold the BB at the rear of the barrel until information technology is fired.^{[ citation needed ]}

The traditional and withal most mutual powerplant for BB guns is the bound-piston pump, usually patterned subsequently a lever-action rifle or a pump-action shotgun. The lever-action rifle was the get-go blazon of BB gun, and still dominates the inexpensive youth BB gun market. The Daisy Model 25, modeled after a pump-activeness shotgun with a trombone pump-activeness mechanism, dominated the low-price, higher-performance market place for over 50 years. Lever-activity models generally have very depression velocities, around 84 yard/southward (275 ft/south), a result of the weak springs used to keep cocking efforts depression for use by youths. The Daisy Model 25 typically accomplished the highest velocities of its twenty-four hours, ranging from 114 to 145 m/s (375 to 475 ft/s).^[two]

Multiple-pump pneumatic guns are besides common. Many pneumatic pellet guns provide the power to use Bulletin board system as a cheaper alternative to lead shot. Some of these guns have rifled barrels, but the slightly undersized BBs do not swage in the barrel, and so the rifling does non impart a pregnant spin. These are the types of guns that will benefit nigh from using precision pb BB shot. The pneumatic BB gun tin attain much higher velocities than the traditional leap piston types.^{[ citation needed ]}

The final common type of power for BB guns is compressed gas, well-nigh commonly the Powerlet cartridges. The powerlet is a dispensable metal 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 CO_ii BB pistol uses a jump-loaded magazine to feed BBs, and a double-action trigger mechanism to sleeping accommodation a BB and erect the hammer. However some guns (either to stay true to the original gun or to make the trigger pull easier) do have a unmarried-action trigger. Either blazon of gun may also have blowback activeness, where CO₂ will button the slide dorsum in addition to firing a BB. When firing, the hammer strikes an internal valve linked to the CO₂ source, which releases a measured amount of CO_ii gas to fire the BB; this also gives it realistic recoil and cage written report features. Many CO₂ BB guns are patterned after pop firearms such every bit the Colt M1911, and tin can be used for training as well equally recreation.^{[ commendation needed ]}

Some gas-powered BB guns use a larger source of gas, and provide machine gun-like fire. These types, about notably the Shooting Star Tommy Gun (originally known as the Feltman) are commonly establish at carnivals. The MacGlashan BB Gun was used to railroad train antiaircraft gunners in the United States Ground forces Air Corps and The states Navy during World War Ii. A popular commercial model was the Larc M-19, which used ane pound (454 g) canisters of Freon-12 refrigerant. These types have very simple operating mechanisms, based on a venturi pump. The gas is released in a constant stream, and this is used to suck the Bulletin board system upwards into the barrel at rates as high as 3600 rounds per infinitesimal.^[iii]

Safety [edit]

BB guns can shoot faster than threescore m/s (200 ft/southward), only are oftentimes less powerful than a conventional pellet airgun. Pellet airguns have the ability to burn considerably faster, fifty-fifty beyond 170 m/s (560 ft/s).^[4] ^[5] ^[6] Although claims are often exaggerated, a few airguns can really burn down a standard 0.177 caliber atomic number 82 pellet faster than 320 m/s (i,000 ft/s), but these are mostly not BB-firing guns.

A BB with a velocity of 45 g/south (150 ft/s) has skin-piercing adequacy, and a velocity reaching 60 g/s (200 ft/s) can fracture os.^[7] This is potentially lethal, and this potential increases with velocity, only also apace decreases with distance. The effective penetrating range of a BB gun with a muzzle velocity of 120 to 180 1000/s (390 to 590 ft/s) is approximately 18 m (threescore ft). A person wearing jeans at this distance would not sustain serious injury. However, even at this altitude a BB notwithstanding might penetrate bare skin, and even if non, could leave a severe and painful bruise. The maximum range of a BB gun in the 120 to 180 thousand/s (390 to 590 ft/south) range is 220 to 330 m (240 to 360 yd), provided the cage is elevated to the optimum angle.

Steel BBs are also notably prone to ricochet off hard surfaces such as brick, concrete, metal, or woods finish grain. Center protection is essential when shooting BBs at these materials, more so than when shooting atomic number 82 pellets, since a BB bouncing off a hard surface can retain a large portion of its initial free energy (pellets usually flatten and absorb energy), and could easily crusade serious heart damage.^{[ commendation needed ]}

Quick Kill preparation [edit]

The U.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 Army by Bobby Lamar "Lucky" McDaniel and Mike Jennings.^[eight]

Legal status [edit]

BB guns are often regulated every bit a typical air gun.^{[ commendation needed ]} Air gun laws vary widely by local jurisdiction.
