Yes, expect many shooting enthusiasts to have one or more suppressors for their firearms; in the same way that they might have optics, lights, and other accessories. Here are a few things to keep in mind when looking for a suppressor for your BB gun.
First, recall that a firearm’s report – the crack of the gunshot – is created by two events: the explosion of powder inside the chamber and the impact of the bullet on the air outside. That’s why a suppressed firearm will often still make some noise; it just won’t be as loud because the second event has been reduced. Second, most BB guns use CO2 cartridges as their power source; these produce very little muzzle flash when fired. As a result, a suppressor isn’t going to do much to reduce the visibility of your shots.
Third, BB guns generally have very short barrels. This means that there isn’t a lot of space for the sound-reducing material inside a suppressor, so don’t expect them to be as effective as those made for firearms with longer barrels. Finally, remember that suppressors can add some weight to your gun, so if you’re looking for a light and maneuverable BB gun, one with a suppressor might not be the best option.
