Inner barrel / Hop Unit Stabilizer O Rings

Apply these o rings to your inner barrel and slide them down u till they make contact with your hop up unit. They key is to install enough o rings until you can not close your front body pin, from there remove one O ring at a time until you can close the front body pin. at this point you will have the perfect amount of O rings to properly seat and seal your hop unit to your gearbox. 

By installing these o rings you are 

- Firmly pressing your hop unit up against your gearbox shell eliminating excess vibrations and removing any movement of the hop unit. 

- Increase consistency in feeding 

- Increased FPS consistency
