Shooting just air (like you probably do a lot when you get a new gun, seriously, everyone does it) is always a LOT louder than actually shooting a ball through the gun.
Heck, the experienced players can tell when you run out of paint just from the sound. So be careful if you try and bluff your way through a game after running out.
A barrel with a lot of porting will be a lot quieter than a barrel with just some porting. The stock Azodin barrel has a rather moderate amount of porting unfortunately.
And bolts, well, they don't actually do that much unfortunately on a stacked tube design.
