An airsoft compensator is a device that is attached to the barrel of an airsoft gun to help reduce recoil and improve accuracy. Similar to a compensator on a real firearm, an airsoft compensator works by redirecting the gases generated by the firing of the gun to reduce the amount of muzzle rise and recoil.
Airsoft compensators are typically made of metal and come in various shapes and sizes, depending on the specific model of the airsoft gun they are intended for. They are designed to fit over the muzzle of the airsoft gun and are secured in place using set screws or other fastening methods.
