Please view our Product Description for our Stabilizer O rings for installation. You will have more O rings than needed, you will insert the hop chamber into the upper and try to close push in the front body pin and close the AEG, if you can’t remove one o ring at a time until you can. You then have the perfect amount of O rings to shim your chamber to your gearbox. 

Choosing the proper nozzle length is crucial for optimal performance. We have a youtube video titled How to Tune an Airsoft Adjustable Nozzle, and in that video I explain the concept behind finding your proper nozzle length. Adjustable or non adjustable nozzle, same concept applies. We found that 21.1 works great with this combination. 

The nozzle length range can be depending on bucking and tappet plate 20.50 - 21.1 mm nozzles.
