An intelligent or smart air restrictor is an internal component found in most modern Nerf blasters.


Intelligent air restrictors can be found in many modern front-loading Nerf blasters. While blasters with intelligent air restrictors have an order in which a blaster will fire darts when it is fully loaded, they allow the blaster to fire darts loaded in any barrel when it is not fully loaded. Because of the intelligent air restrictor system, it can detect what barrels are loaded and which are not, and will skip any unloaded barrels to the next available dart to fire.

List of blasters with intelligent air restrictors


  • More that one dart can be fired at a time by not loading darts into blasters properly. If darts are not loaded in all the way, the air restrictor system will not recognize them. If it does not recognize any loaded darts, the blaster will discharge air out of every barrel when it is fired.
