Real Deal Airsoft 21.4mm Nozzle CNC

CNC Aluminum Construction 

21.4 mm

Single O Ring internally 

Lubricate o ring  before use 

Comes with 2 different size thickness o rings. Use which ever size works best for your application. Tolerances between brands are slightly different, some cylinder heads you may need to use the thinner o ring where others may need the thicker. You are looking for a snug fit but not too snug that the nozzle can’t move along the cylinder head shaft  

Lubricate o rings and cylinder shaft. Real Deal Airsoft Multi Use Grease Recommended  

Most stock hop units use the standard 21.4 mm spec nozzle. If you are planning on keeping your stock hop chamber, this nozzle would be a good upgrade for you.   

We have found that in high rate of fire builds, nozzles with two o rings produces a higher amount of friction as it travels along the cylinder head shaft. In a HROF build, less friction means seating the bb and sealing against the bucking lips faster.
