Co2 Airsoft Guns: What's So Great About Those?
Airsoft guns can be classified in several ways. The first, and most common, is by the type of power source used in them. Both electric and mechanical airsoft pistols and rifles are available, but the difference is simply the power source used. The second is more complicated; we will only focus on the Pneumatic type of airsoft gun.
Co2 Airsoft guns can be split up into two general categories: spring (pistol) and gas-powered airsoft guns (rifle). But for this post, we will only be focusing on the Pneumatic gas-powered airsoft rifles. Co2 gas guns function by using a canister inserted into the rifle's magazine; after that, it is filled with compressed air. Once it is loaded into the rifle's magazine, the canister functions like the pistol's clip.
This leads us to the next significant difference between the two types of guns - the working mechanism. Gas guns use a series of pressure-relief ports in the side of the canisters, where the canisters are inserted. When the port detects the pressure in the gas, it opens up a valve that allows the gas from inside the canisters to be released, shooting out the port. This means that the bbs are compressed inside the canisters before they hit the air; hence, "compressed bb." As the pressure inside the bb increases, so does the pressure of the recoil air charge.
The slide assembly is one very distinguishable characteristic of all Co2 guns, especially those of the pistol class. Slide assemblies in pistol guns have a protruding slide rod that connects the slide to the frame. These rods are hinged together and then bend backward to allow the slide to be cocked once it is in place. The fall is then secured by a sliding block that is attached to the frame. A similar type of block is used in hammer clicker guns.
Because the mechanism used in electric powered airsoft guns differs from the mechanism used in gas guns, the triggers used in these guns tend to be slightly different. Because the mechanisms are different, the trigger actions must also be other. Trigger sets are used in both gas and electric powered guns; however, gas guns' trigger mechanism is different from the trigger mechanism in electric guns.
In an electric-powered airsoft gun, the firing pin strikes a firing pin stem, which sends the firing pin down into the barrel. A trigger is then used that pushes the firing pin down into the barrel to cause the gun to fire. The trigger mechanism differs from one gun to another. In some guns, the trigger is a piece of metal attached to the buttstock. This is called a "bump trigger," and in other guns, the trigger is a part of the sear.
In gas-powered airsoft guns (GAS), the firing pin strikes a gas piston, which creates a compressed gas that pushes the bullet out. The mechanism of this type of gun is identical to that of the spring-loaded pistol or rifle. In a GAS, the sear pushes down on the sear caddy, which pushes down on the slide. Once the slide is in contact with the bullet, the sear caddy pushes the slide up and pushes the bullet up through the barrel. The firing mechanism in a GAS is different than the mechanism found in electric guns.
All the above discussion about different mechanisms for different airsoft guns comes from the fact that all require converting energy to kinetic energy and firing the shot. This process is similar to that used in a real firearm. However, with an airsoft gun, since the energy cannot be converted directly to kinetic energy, it must be converted somewhere else, such as through compressed air coming through a valve or a nozzle. Thus, the mechanical design of the gun requires a means of converting energy to kinetic energy, which means that there must be some magazine. Magazines in an airsoft gun are typically small, plastic cases that hold many shots.
