Correct process of testing air nozzle length

The hop-up rubber won't necessarily hold the BB in place if there's no pressure on the nub. I usually just get a nozzle that's similar to the stock one if I have to replace it. I prefer to use the stock nozzle and cylinder head if possible to avoid fitment issues though.
