For M4A1 and M16A2 (M4/M16) AEGs
Air Seal Nozzle
Most of the stock AEG air nozzles don’t reach the max air compression achievable. This is because they don’t have an O-ring. The O-ring these SHS air nozzles come with allow you to reduce air leakage and can possibly fix a gun with very little compression. A high quality SHS air nozzle is one more way to pull all of the performance out of your AEG possible.
