Global types of Airsoft guns
Airsoft has many types and each has its style, functionality and uniqueness.  Here's the the global types of Airsoft guns:

Spring powered


Spring-powered airsoft guns
Spring-powered airsoft guns
Spring-powered airsoft guns are single shot devices that use elastic potential energy (EPE) stored in a spring to compress air to launch an airsoft pellet down the barrel of the gun. The user must cock a spring gun prior to each shot. This is typically achieved by pulling back the slide (pistols), bolt (rifles), or the grip on a shotgun, which in turn compresses the spring and makes the gun ready to fire. Because of this, these guns are by definition incapable of automatic or semi-automatic fire. Spring-powered airsoft guns are generally not as powerful as gas but are more powerful than electric models, although some spring shotguns and bolt-action rifles can be very powerful and shoot at velocities of 400–700 ft/s (120–210 m/s). These are generally inexpensive, excluding the high power bolt action sniper rifles and shotguns, and may not last long (depending on the quality) because of the tension created by a powerful spring. However, many spring guns can be modified and upgraded to last longer and shoot better.

While most electric guns also use springs for propulsion of the BB, they are not considered to be in the same category as the single-shot spring-powered guns. Low-end spring guns tend to be much cheaper than their electric-powered equivalents due to their simplicity and lack of electrical components (spring assembly, electric motor, battery, and battery charger) and thus are widely available. These guns are less suited for competition because they are at a disadvantage against automatic guns in close combat and do not provide enough accuracy and power for long-range use. There are some exceptions, however, as higher-end spring-powered airsoft rifles can be quite expensive; these guns are typically suited for "marksman" applications in airsoft matches and provide competitive muzzle velocities. Additionally, pump shotguns are sometimes used for both short and longer range engagements. In colder weather, spring pistols are more reliable than gas-powered pistols and even the batteries on AEPs (Automatic Electric Pistols) both of which can be adversely affected by extreme cold.

This represents one of the major advantages of spring-powered airsoft gun, as it can be fired in any situation, without reliance on an external source of power, such as batteries or gas. The lack of reliance on external power sources causes some players to favor spring-powered guns. Spring guns are also less susceptible to the effects of water, where a battery-powered gun could malfunction when wet.

Spring-powered weapons are often cheaper than electric or gas powered weapons. They are also more readily available in most department stores. Because of their price, availability and simplicity, spring guns tend to act as "training guns" to bring new players to airsoft games and are considered the primary weapon of "backyard skirmishes". Almost all airsoft players at some point owned a spring weapon, whether for its actual use in a competitive event or for the replica value since some airsoft weapons are only available as spring versions. However, some airsoft players still rely on sniper-rifle type spring guns as a primary arm due to the reliability, high power and accuracy, and low noise, as well as their ease of repair and modification compared to electric powered guns.

To be eligible to purchase a spring-powered airsoft gun, a person has to be of at least 18 years of age in the United States but different localities might have different laws.

Electric guns


Automatic electric guns:

Automatic electric guns
Electric-powered airsoft guns typically use a rechargeable battery or batteries to drive an electric motor, which cycles an internal piston/spring assembly in order to propel the pellets. Automatic, 3 round burst, and semi-automatic operation is possible which gives these guns the popular name "automatic electric guns" or AEGs. These guns often attain muzzle velocities from 150 to 650 ft/s (46 to 198 m/s) and rates of fire of between 100 and 1500 rounds per minute. They are the most commonly used and widely available type of airsoft gun.

These type of guns were developed in Japan and the Japanese company Tokyo Marui dominates the market. In a Tokyo Marui AEG, the motor drives a series of 3 gears mounted inside a gearbox. The gears then compress a piston assembly against a spring. Once the piston is released, the spring drives it forward through the cylinder to push a pellet into the chamber, through the barrel, and forward from the muzzle. Many manufacturers have now more or less replicated this basic model, adding reinforced parts or minor improvements. These guns are powered primarily by nickel metal hydride (NiMH) with varying voltages and milliampere hours ratings. The most common battery is an 8.4 V large battery (between 2200 and 5000 mAh.) Also available are "mini" and "stick" batteries, which generally have 900–1600 mAh capacities. Voltages for NiMH batteries range from 7.2 V, all the way up to 12 V. The rule of thumb usually is the higher the mAh, the longer the battery lasts while the higher voltage, the higher Rate of Fire (RoF). Recently, however, Lithium-Polymer, or Li-po, batteries are becoming more popular in the airsoft world. These batteries can last longer and have higher mAh and Volts while at the same time they are small and light. Li-po batteries are usually at 11.1 V or 7.4 V varying in mAh from 500 mAh to 6500 mAh.

External modifications, such as metal bodies and reinforced plastics that make AEGs look and feel even more realistic, have become very popular. AEG manufacturers such as Classic Army and Tokyo Marui produce replicas that are visually nearly identical to their real counterparts. Tokyo Marui uses an ABS plastic, whereas Classic Army features full metal bodied guns and stronger furnishings. Most AEGs produced as of late are designed to be as visually realistic as possible.

The three most common AEGs on the field are the AR-15 series (M16 rifle, M4 carbine, etc.; sometimes referred to as the ArmaLite or Colt series), the Heckler & Koch MP5 series, and the AK or Kalashnikov series. Also increasing popular is the Heckler & Koch G36 and more recently, FN P90. Subsequently numerous parts for repairs and modifications are commonly available for these rifles. AEG models range from a simple pistol to an RPG (Rocket Propelled Grenade) all the way to a Minigun.

Low powered electric guns:

Called low powered electric guns (LPEGs) to distinguish them from the original, more expensive and more powerful AEGs even though their mechanical/electrical design and operation is similar. They are not to be confused with Mini Electrics (described below). Originally they were only of novelty value, often regarded below spring operated guns due to their construction and low velocities. Since there are spring action guns that can notably outperform the true low-end LPEGs and can be found at comparable prices, they are generally considered to be better choices.

Medium price electric guns:

Some companies - like UTG with their popular MP5 and AK-47 models - have improved their quality to such an extent that some models are now considered simply as mid-ranged AEGs that are more affordable but still reasonably effective. Among airsofters, these are commonly called middle priced electric guns (MPEGs). Sometimes, MPEGs are copies or 'clones' of designs by full-price manufacturers like Tokyo Marui. As of late 2008 a small number of MPEG brands such as Echo-1/Jing Gong, and CYMA are considered by many to approach the quality and match the performance of the originals, at less than half the price. "Fully compatible" MPEGs imitate the Marui or Classic Army originals so precisely that standard upgrade parts will work with them, making it possible to hot-rod an MPEG to well beyond stock out-of-the-box AEG performance.

Electric blowbacks:

Electric blowbacks
Electric blowbacks, also known as EBBs, are high-end AEGs which generally run from a rechargeable 9.6 volt battery. Most models utilizing this system are rifles. EBBs simulate the blowback action of a real pistol or rifle but generally have less of a kick. Essentially an AEG in design, EBBs are just as powerful. However, a drawback to having the blowback feature is that the battery is quickly depleted, additionally blowbacks can cause extra stress on the gear box which may result in the gearbox's shorter life span. The blowback system can be disabled with some tinkering.

Electric blowback can also refer to a feature in some higher-end guns which offers more realistic operation. Companies such as G&G now offer guns such as the combat machine M4 and the combat machine "RK47" which has moving parts linked directly to the main mechanism of the gun, such as the bolt. Echo 1 has recently released a Blowback MP5SD. Also, APS (Accuracy Pneumatics Shooting) makes EBB M4A1, M4 Commando, and the AK47. The M4s also have 3 others with an RIS unit. These weapons perform identically to similar non-blowback offerings, with the added realism of reciprocating bolts and some recoil. Most models incorporate pneumatic blowback systems but some feature mechanical systems.

Mini electrics:

Recently, the company Well, well known for its spring guns, began manufacturing a range of battery powered guns in miniature size that fire only full automatic. They differ from GPMGs in that they are not replicas of real firearms, being miniaturized version of real firearms, mostly made of black or clear plastic.

They have a small bb capacity, usually between 50 and 100 rounds, but they have fair range and a functional hop-up. They have become very popular in recent years, and are now being manufactured by Tokyo Marui. These “minis,” as they are referred to, are not a viable option in games against AEGs since their small ammo capacity, short range and poor far range accuracy leave their wielder at a large disadvantage. Mini electric guns are able to compete with spring pistols at close ranges however, primarily due to their higher rate of fire.

Automatic Electric Pistols:

Automatic Electric Pistols, abbreviated AEPs, were first introduced by Tokyo Marui in 2005 with their Glock 18C (followed later by a Beretta 93R model). They were the first handguns to incorporate an electric powered system that is capable of fully automatic operation.

In cold weather, AEPs are often considered better sidearms than gas powered pistols, because batteries are not as badly affected by frigid weather. Gases like CO2 and green gas are stored in liquid form and require heat in order to vaporize. A gas pistol at 10 °F (−12 °C) will usually only get one to two usable shots from a full magazine, and even will be at reduced power because of the lowered pressure of the gas.

Because the AEP gearbox and battery are smaller, the velocity of AEP BBs (usually between 200 to 280 ft/s (85.3 m/s)) is relatively slow by the standards of airsoft simulations, rendering them useful only for close-range simulation. However, the advanced hop up units on these new guns tend to compensate for the low power and can produce an effective range comparable to those of an AEG. CYMA has made a clone Glock 18C, which is a lower priced alternative.

An AEP differs from electric blow-backs because the AEP has a fixed slide (in which there is no external movement of the slide during operation), while an EBB simulates the "blow back" action in the slide experienced in a real pistol or Gas Blow Back (GBB). An AEP, however, has much more power and accuracy.

One of the newer AEP-styled guns is the Marui replica of the Heckler & Koch MP7. It is considerably larger than either of the other guns, and can be upgraded to a much higher power through the use of an external battery, but uses the same system as the AEP, so the classification is ambiguous. It is slightly more powerful than the others and is a suitable choice for CQB (Close Quarter Battle) games due to its small size and decent barrel- to gun-length ratio.

Some semi-automatic pistols can be modified to be automatic pistols. To make them more effective, they use rechargeable batteries supplied with the gun, and can be replaced with a larger battery to make their ROF higher.

Due to restrictions on size, either the electric motor or batteries have to occupy space in the hand grip, reducing the available space for a magazine. Because of this no AEP uses a full size magazine found in most gas powered pistols.

In addition, most AEPs are constructed almost entirely of plastic and have a light, toy-like feeling to them.

Gas powered airsoft guns

These guns are capable of automatic and semi-automatic operation. The most common gases used are "green gas" and Propane which requires an adaptor, HFC-134a is also commonly used, particularly with pistols which have plastic sliders due to the lower pressure giving a smaller chance of damage to the weaker slide. Less commonly used gases include "red gas" (which is actually HCFC-22), CO2 and nitrogen/high pressure air. It is unlawful to use HCFC-22 as a propellant in the US. HCFC-22 is a Class II ozone depleting substance and its use as an aerosol propellant has been banned since January 1994 under section 610(d) of Clean Air Act.

Red gas is usually avoided unless the airsoft gun has undergone modification, as its relatively high critical pressure can cause damage to the airsoft gun, such as breakage of the slide or bolt. CO2, nitrogen, and high pressure air are less common because they need to be stored at higher pressures than "green gas" or HFC-134a.

The first ever gas powered airsoft guns were commonly referred to as 'classic' guns, owing to their age. These guns were most commonly powered by liquid propellants such as R-12 (Which was marketed by the Japanese as FLON-12 or DuPont tradename Freon 12)CFC-12 feed system with a majority of the configurations containing two tanks, one containing the CFC-12 and one used as an expansion tank, and the gun itself. CFC-12 was a commonly used refrigerant for car air conditioning and refrigerators. It is considered a highly potent ozone depleting substance and listed as a Class I Ozone Depleting Substance by the US EPA. Its use as a general purpose aerosol propellant has been banned by the US EPA since March 1978 under 43 FR 11301 for use in aerosol use with a very few exceptions. Its use is also banned in many countries under United Nations treaties. On Dec 31, 2008, the use of CFCs for medical inhalers were banned.

Later users modified these old guns to be powered by regulated CO2 canisters or nitrogen/high pressure air bottles to increase power and consistency. However, these guns have largely been superseded by the newer and more versatile AEGs, or automatic electric guns. One of the reasons for this is because the most commonly available propellant, R-12, is costly. Additionally, at high flow rates, liquid propellants tend to cool down, eventually freezing. As cooldown progresses, the rate of fire gradually decreases until the gun ceases operation. The user would then be forced to wait for the propellant to warm up again. CO2 is not affected as badly by this tendency, and nitrogen/high pressure air is immune to it. Furthermore, if liquid propellant is introduced into the gun's mechanism, rubber parts can freeze and eventually damage the gun. However, it is unlikely for this to occur since once the gas is released from the containing cylinder it instantly turns back into its gaseous state, and expands rapidly. It is doubtful whether the retained pressure behind the BB before it begins to accelerate down the barrel is enough to keep the gas in a liquid form. Also, any gun that is expected to be exposed to the intense cold of de-pressurizing gas should have materials that can handle it.

Gas power tends to be used in airsoft pistols where size constraints make electric-powered mechanisms impractical. Other instances where gas is favored are where adjustable velocities are required or where a blowback feature is desired. A blowback feature is a mechanism which cycles a slide or bolt to better simulate a real firearm's operation. Because of the mechanical complexities involved with distributing and regulating gas, these guns have largely given way to electric guns for less specialized applications, however, they still remain favorable amongst most airsofters. They are not just limited to pistols; submachine guns, sniper rifles and assault rifles commonly use gas mechanisms. Whilst the submachine gun replicas typically feature a blowback mechanism similar to the pistol replicas, sniper rifle replicas usually omit the blowback mechanism in favor of reduced recoil and increased muzzle velocity.

Along with using gas to power guns, it is also applied for use in replica grenades. These grenades are either projectiles, fired from a grenade launcher such as the M203 or GP-25, or throwable. The shells work on the system of an internal piston, filled with gas. Either a series of BB's or in some cases a rubber or soft foam head is seated in or on top of the shell. When the pressure is released the projectile(s) are shot from the launcher sent downrange.

In the case of the throwable grenades, inside the grenade there is a similar piston to the one used in the shells, but is on a literal "timer" that allows the user to clear the area of effect. BB's or powder act as the projectile in the case of these grenades. Currently both types of grenades are not very common, mostly because grenade launchers are quite expensive and the throwable grenades are not very reliable.

Hybrid guns


Hybrid Airsoft guns are the newest type of airsoft guns on the market. Hybrid airsoft guns are basically standard AEGs or Gas Blowback Airsoft Guns with a "little extra reality" built in. These guns are usually more powerful.

AEG Hybrid Operation:

The magazine is loaded with shell cases, each containing a single plastic pellet. These shell casings can have a small red cap, the same as those found in any child's toy cap gun placed on the top of them. These guns feature an electrically powered, full blowback system and operate on a "round-per-shell" basis such that for every pellet fired, a shell casing is ejected and the cap is fired providing a realistic sound and smoke effect. Since its debut, the only Hybrid guns seen on the market are TOP M4A1, as well as M1 Garand, Kar98, and other rifle models. These guns are the least common type of gun on the market today and are generally used by collectors and re-enactors rather than skirmishers.

Gas Blow Back Hybrid Operation:

Hybrid Gas Blow Back Airsoft guns are quite similar with hybrid AEGs and their operations are similar with Gas Blow Back Airsoft Guns. A single 6mm pellet is still loaded to a shell casing. Then it is placed into a magazine. The Airsoft Replica itself also has a tank for compressed gas as propellant (Such as Green Gas). So as the slide/bolt is pulled back, it loads a shell into the chamber. As the trigger is pulled, it releases a small burst of propellant and the pellet is forced out the barrel.

Training Weapons


Training Weapon Spring Airsoft Guns
Training Weapon Spring Airsoft Guns
Airsoft gun manufacturer, Systema Engineering (PTW) developed a line of airsoft guns and accessories intended for military and law enforcement training. These airsoft guns are made of aircraft grade aluminum combined with stainless steel parts that gives strength, stability, weather protection, and easy maintenance. These training weapons offer a more realistic display of military weapons. Unfortunately they have been plagued by reliability problems and parts availability. They have also had models banned from the US due to them being able to be converted into real fire arms. Two manufactures, King Arms and KWA came out with ATF approved GBBR AR15 platforms that allowed for correct weapons tear down, manipulation, and function that were designed for military use, but were also legal for US citizens to own. The King Arms model required upgrade parts out of the parts to give it reliability, though the KWA was plagued by a weak hop up system, but otherwise reliable.

Classic guns


Classic airsoft guns are usually the older variety of airsoft guns which are gas powered though in the recent past other manufacturers have found interest in them. Unlike the gas rifles of today, they can run on either an internal tank using conventional airsoft gas or use an external CO2 or HPA tank much like a paintball gun. These type of guns generally cost considerably more than the standard AEGs. Some models, such as those made by the Sun Project, feature a type of "recoil" provided by these guns. The rate of fire on these can be regulated by the amount of air being fed through the system, versus using different battery voltages in an AEG. Other manufacturers for example are PolarStarAirsoft and Daytonagun.

Different ammunitions


One will use differing kinds of ammunitions in air guns. a number of them ar listed below: Pellet most typical ammunition is lead diabolo pellet. This projectile includes a hollow base and comes in numerous head size. BB atiny low ball usually fabricated from steel with copper or atomic number 30 coating, pellet is employed for indoor follow, casual plinking and coaching. DartsDarts and arrows also are used as ammunition in air rifles.
