Airsoft Gas vs. Electric (AEG): What Sets Them Apart?

Airsoft guns come in a wide variety of models, brands, and roles, but they can primarily be categorized based on their propulsion method: gas or electric. The key distinction between these two types is how they propel BBs. Electric airsoft guns (AEGs) use a battery-powered motor to drive a spring and piston mechanism, whereas gas airsoft guns utilize compressed gas to propel BBs. These two systems differ not only in their mechanics but also in terms of cost, performance, and realism. In this blog, we’ll break down the characteristics of both electric and gas-powered airsoft guns, and then delve into a detailed comparison of their respective advantages and drawbacks.

What is an Electric Airsoft Gun?

To understand what an electric airsoft gun is, it’s essential to grasp its inner workings. Electric airsoft guns, or AEGs (Automatic Electric Guns), use a complex mechanical system housed within a gearbox. This gearbox contains three main gears and a motor, converting electrical energy from the battery into mechanical force.

How Electric Airsoft Guns Work

The process starts with pulling the trigger, which closes the electrical circuit, allowing power to flow from the battery to the motor. Once energized, the motor begins to spin, engaging the first gear, known as the bevel gear. The bevel gear is held in place by an anti-reversal latch to prevent backward motion. It then drives the second gear, called the spur gear, which in turn engages the third gear, known as the sector gear.

As the sector gear rotates, it pulls back the piston to compress the spring. Simultaneously, a small nub on the sector gear pulls back the tappet plate, which retracts the air nozzle towards the cylinder. This action allows the next BB to feed into the hop-up chamber. Once the tappet plate returns to its original position, it chambers the BB.

When the sector gear releases the piston, the compressed spring propels the piston forward through the cylinder, forcing air out. This rapid movement generates a burst of pressurized air that propels the BB out of the barrel, ready for your next shot.

Pros of Electric Airsoft Guns:

Types of Batteries

NiMH Batteries

Nickel-Metal Hydride (NiMH) batteries are known for their improved energy density and longevity compared to older Nickel-Cadmium (NiCd) batteries. One of the key benefits of NiMH batteries is their resistance to the memory effect, a phenomenon where batteries “remember” the last charge level and experience reduced capacity over time. This makes them a more reliable and efficient choice for extended use.

In addition to their performance benefits, NiMH batteries are also more environmentally friendly. They do not contain toxic heavy metals such as cadmium or mercury, making them safer to dispose of and easier to recycle.

LiPo Batteries

Lithium Polymer (LiPo) batteries, utilizing a polymer electrolyte instead of a liquid one, offer exceptional versatility in design. They can be manufactured in various shapes and sizes, making them ideal for compact and lightweight applications like airsoft guns and drones.

LiPo batteries stand out for their high energy density, allowing them to store more power relative to their size and weight than any other comparable battery. Their high discharge rate supports high-drain applications, delivering quick bursts of power when needed. Additionally, LiPo batteries have a low self-discharge rate, which means they retain their charge over extended periods. With proper care, they also boast a long lifespan.

However, LiPo batteries require careful handling. They need specialized charging and discharging procedures to prevent overcharging or over-discharging, both of which can be hazardous and potentially damage the battery. They are also sensitive to temperature fluctuations, and exposure to extreme heat or cold can affect their performance and longevity.

What Are Gas-Powered Airsoft Guns?

How Gas Airsoft Guns Work

Gas-powered airsoft guns utilize compressed gas, typically stored within a reservoir inside the magazine, to propel BBs. Most gas airsoft guns are charged through a fill valve located at the bottom of the magazine, where gas or CO2 is injected.

When the trigger is pulled, a pin strikes a release valve on the magazine, allowing the compressed gas to flow from the reservoir through an outlet at the top of the magazine and into the gun’s blowback unit. This unit, housed within the slide or bolt, contains a piston and cylinder that expand as the gas enters.

The gas is then divided into two functions: some of it propels the BB down the barrel, while the remaining gas forces the slide or bolt to recoil, cycling the gun. This action cocks the hammer and chambers the next BB, readying the gun for the next shot. The mechanism closely mimics the operation of a real firearm, providing an authentic experience. When the magazine is empty, the slide or bolt locks back, just as it would in an actual pistol or rifle, adding to the realism and functionality of the weapon.

Pros of Gas Airsoft Guns:

Authentic Realism: Gas airsoft guns deliver an unparalleled level of realism, closely replicating the experience of handling a real firearm. With blowback action that simulates actual recoil, and the option to load shells or cartridges similar to live ammunition, these guns provide a highly immersive and authentic shooting experience that electric airsoft guns can’t match.
Exceptional Versatility: Gas airsoft guns are available in a diverse range of styles, from pistols and rifles to shotguns, making them adaptable to various play styles and game scenarios. Whether you’re engaging in intense close-quarters combat or taking precision shots in long-range skirmishes, there’s a gas airsoft gun to suit every need.

Cons of Gas Airsoft Guns:

Higher Cost: Gas airsoft guns typically come with a higher price tag compared to electric models. Additionally, the need for gas canisters and maintenance tools can increase overall costs, making them a more expensive choice in the long run.
Increased Maintenance: Gas airsoft guns require more frequent upkeep. Gas canisters need to be regularly refilled or replaced, and the guns must be cleaned and lubricated consistently to maintain optimal performance.
Limited Playtime: The playtime of gas airsoft guns is restricted by the capacity of the gas canisters. Once the gas is depleted, the gun needs to be refueled or have the canister replaced, which can interrupt gameplay.
Temperature Sensitivity: Gas airsoft guns are susceptible to performance fluctuations in extreme temperatures. Cold weather can reduce the efficiency of the gas, impacting the gun’s reliability and effectiveness during play.

Different Types of Gas for Airsoft Guns

Green Gas – Green gas is primarily propane infused with a small amount of silicone oil. The silicone oil serves a dual purpose: lubricating and cleaning the internal components of green gas airsoft guns as they are fired, helping to maintain their performance and longevity. Many green gas products also contain additional additives to neutralize the strong odor of propane, making them more pleasant to use.

While it’s possible to use regular propane in green gas airsoft guns, it’s not advisable. The silicone oil in green gas is crucial for keeping the gun’s o-rings properly lubricated and ensuring smooth operation. Using pure propane can lead to increased wear and tear, potentially compromising the gun’s functionality over time.
