Call them what you want: Suppressors, Silencers, Moderators, in Airsoft they all pretty much mean the same thing, the tube you stick on the end of your gun which makes it look super tactical cool, and for the most part, they really... don't do anything.
For the most part, they don't really do anything. They change the noise of the replica as the Air which leaves the barrel is disrupted, but other than that not really. Most of the noise an Airsoft replica makes when its shot is from the main body of the replica. They aren't sealed so noises can escape through the body.
When it comes to what causes the sound, with a gas gun most of the sound comes from the slide and the gas escaping out the top, and with an AEG the noise comes from the motor and gearbox, and you ain't stopping that.
Some suppressors are foam filled which absorbs the excess Air coming out the end of the barrel which usually causes the 'pop' sound as you fire the replica. This does make the replica harder to identify, but if you're shooting at Airsoft ranges the sound of replica's gearbox or gas system working will give you away anyway.
Saying that, 99% of all Airsoft suppressors do nothing to sound, though there are some exceptions which have practical uses.
Suppressors look cool. Pretty much, 100% of the time, 90% of the time, they're just for looks. The longer your gun, the cooler it is, that's how it works right? A suppressor adds +3 to your super sneaky rating.
Some people like to increase the length of their inner barrels for whatever reason they decide in an attempt to make their Airsoft replica shoot further or more accurately. Finding longer replacement barrels for some replicas can be a nightmare, so if the inner barrel sticks out the end a few inches then they can be easily covered with a mock suppressor.
It keeps the replica looking realistic, rather than having a silver or brass barrel hanging out the end, and also protects it from getting damaged.
You might see a lot of people rocking suppressor in dark gaming environments and wanted to get yourself some glowing BBs. If you've ever played in a dark Arena or CQB site then without a doubt you'll have seen someone using tracer rounds, sending hundreds of glowing angry BBs down range towards you, they look really cool.
The thing is, without a light source the BBs don't glow, they need to be 'charged' before they're fired. You can leave them in bright light all day long and they'll only retain their glow for a short amount of time, no where near long enough to play a game with them. The solution to the problem is to 'charge' the BB before they leave the barrel, and before you knew it the Airsoft Tracer Unit was invented.
Airsoft tracer units contain an ultra bright LED and trip mechanism, so as the BB travels down the tracer unit it activates the LED for a short amount of time to create a flash and 'charge' the BB to its max just in time for you to watch is gloriously float down towards your enemy.
Not only do tracer BB look brilliant indoors, but it also allows you to see if the other player are taking their hits... not that they ever wouldn't... right?
For AEG Airsoft Replicas a barrel extension usually does nothing, but for Gas guns they can make the world of difference. Though not widely used, barrel extension suppressors line up with their own inner barrel with the inner barrel of the replica, and push them together using a spring to cause a seal.
Because the barrel is longer, the gas has more time to expand, causing more pressure, and increasing the power of the shot (for better or for worse).
These types of barrel extensions were all the rage a few years ago, but have pretty much disappeared. The only exception to this is the ASG MK23, which comes with a mock suppressor which is a barrel extension, and can increase the FPS of the replica between 50-100fps!
Does putting a suppressor on an airsoft pistol do anything?
If you're looking to reduce the volume of the replica: no. The suppressor only affects the noise coming out of the barrel, the majority of the noise caused by Airsoft replica is typically what powers it. For example, on an gas pistol the noise from the gas coming out the top of the slide and it racking back, and on an AEG from the gearbox and motor. Some items do have a practical use such as as a Tracer Unit or barrel extension, but sound wise, nothing.
VisitorDo Airsoft silencers use baffle like a real guns suppressor?
No, Airsoft suppressors tend to use a round of foam which covers the inside face of the suppressor, and is then held in place by a spring to prevent it from falling in the way of the shot. People have tried making baffles for Airsoft but they don't really work.
Hope this post has been informative and given you a better insight into the ins and outs of Airsoft suppressor. Let us know in the comments below if you rock an Airsoft Suppressor or Silencer on your pew pew! Most of us do, just because they look cool.
