SHS Air Nozzle O-Ring - An often overlooked aspect of gear box maintenance, the o-ring inside your nozzle can wear out or may not be a perfect match for your cylinder head. These little o-rings are perfect upgrades / replacements for nozzles that already have o-rings. Stop beating your head against the wall wondering why your 120 spring is only resulting in 330 fps, and get one of these today! (please note: packaging may be generic or labeled as 'Rocket Airsoft', but is made by SHS OEM)
Dimensions: 8mm outer diameter; 5.25mm (inner is approx, hard to measure). Fits all standard AEG air nozzles.
