Blowback Versus Non-Blowback Airgun Comparison
In this Comparison video I go through the benefits and shortcomings of both Blowback and Non-Blowback Airguns. I focus mainly on Airguns but there is a definite crossover with Airsoft guns.
Here are some basic statements that best describe both Blowback and Non-Blowback Airguns.
Blowback Airguns:
Blowback Airguns usually have a movable slide that moves back and forth with each shot.
Sometimes the blowback operation is internal (Internal bolt) so there may not be an external moveable slide.
Some CO2 is used to move the slide rearwards in a Blowback Airgun.
The Blowback motion of the slide with some blowback airguns can also cock the hammer or internal striker allowing for true single action trigger pull. But not always!
Some Blowback airguns have the potential for full auto capabilities since they can have a true semi auto action.
There is some noticeable recoil from the Blowback action simulating the recoil of a real gun.
Non-Blowback Airguns:
Non-Blowback Airguns can have fixed or movable slides but they will not cycle back and forth with each shot.
Non-Blowback Airguns tend to have less working parts since no Blowback valves are required or even a moveable slide.
There are some Blowback and Non-Blowback Airguns that field strip similarly to their real steel counterparts but this is most commonly found in Blowback Airguns.
Non-Blowback Airguns require the shooter to cock the hammer for single action shooting or use a double action trigger pull for semi auto like performance.
Pros:
Blowback Airguns:
Blowback Action causes a noticeable recoil which makes the airgun feel more realistic.
Blowback Airguns in some cases have true semi auto action with true single action triggers which mimic the authenticity of the real steel versions of the guns they replicate much better making them better training tools.
Having some recoil makes blowback Airguns potentially better training tools.
Blowback Airguns look really cool when shooting them and are great action prop guns.
Non-Blowback Airguns:
Non-Blowback Airguns tend to have less working parts so less to go wrong and more reliability.
Non-Blowback Airguns can be more accurate since the recoil from the blowback is not a factor.
Non-Blowback Airguns have more potential power and more shots per CO2 since no CO2 is robbed for the blowback operation.
Cons:
Blowback Airguns:
Blowback operation can rob some of the power and will also rob how many shots you get from the Airgun.
Blowback Airguns are effected even more by cold weather and the cool down effect.
The recoil from Blowback Airguns can effect accuracy for some shooters.
Non-Blowback Airguns:
Non-Blowback airguns are generally double action when shooting semi auto and so the trigger pull will be longer and heavier.
Non-Blowback Airguns do not replicate the recoil action of a real gun.
Non-Blowback Airguns do not look as cool to shoot and are not as good of an action prop gun.
