A threaded barrel gun can be fired without the suppressor, but it will be significantly louder. The suppressor helps to muffle the noise of the gunshot, so firing without it will result in a much louder noise. If you’re trying to be stealthy or not attract attention, it’s best to use the suppressor.
No, a suppressor is required for a threaded barrel gun to function properly. The suppressor helps to keep the noise down and makes it so that the user does not have to wear ear protection. It also keeps the muzzle blast from being too intense and damaging the user’s eyesight.
Although you can technically fire a threaded barrel gun without the suppressor, doing so is not recommended. Without the suppressor, the gun will be significantly louder and could potentially damage the threads on the barrel. Additionally, firing a gun without a suppressor can be unsafe because it increases the risk of muzzle flash and debris being ejected from the muzzle.
