An expansion chamber is screwed into the location typically occupied by the regulator, and are most commonly used for co2. They are less effective than regulators, as they only allow the co2 to expand instead of actively regulating the pressure.
Fifty caliber, but it is more of a toy than a paintball gun.
A part inside of the breach that uses a laser to detect if there is a ball in the chamber. It does this so that the bolt does not chop the paintball in half before it is fully in the chamber and ready to fire.
It depends on the gun, but "both" is an acceptable answer.
A hopper is like a holder a hopper usually holds 180-200 paintballs, a hopper feeds paintballs down into the chamber of your gun were the bolt can force it out the barrel. I strongly recomend you invest some money in a good electronic hopper. A tank holds air which is like food for your paintball gun, it is used to operate all the parts in your gun, there are three types of air used in a paintball gun there is co2, which is not good for your gun because it might freeze your gun up and god forbid u might get frost bite but is rare, there is compressed air which is the best for your gun, then there is nitrogen which is better then co2 but worse then compressed air.
the ASA (air source adapter)
The sizes 9 oz and all the way up to 20 oz can be used for paintball gun. Some of the paintball guns are supposed to be used by the larger tanks. So the size of tank depends on your paintball gun.
Where the air tank or co2 tank normally attaches
On a paintball gun C02, or High pressure air is necessary. It is compressed air that, when the trigger is pulled and the marker fires, propels the paintball out of the barrel.

Be careful:First off, you must likely have a spyder or spyder replica (copy, clone, wanna be, etc.).Bottom line is if you have a pin hanging out the side of your gun here is what to do:If you pull the pin out, both the upper chamber (where the bolt is) and the lower chamber (where the air passes through) will spring out! This will happen because 1) they are connected (top and bottom chamber) and 2.) because there is a spring in the bottom chamber which assists in re-cocking the semi automatic (or fully) paintball gun.Before you do any work on the gun you want to make sure you have disconnected the air. Manually cocked the gun after doing so, and test fire the gun. In your test fire(s) you are trying to make sure all the air is out of the gun. Shoot the gun repeatedly until all the air is gone. Once all the air is out, the gun is safe to work on.So, when pulling the pin on your paintball gun (after all the air is out) you may put your hand on the back of both chambers (bolt and the bottom [velocity adjuster usually]) and catch the parts before the fall to the ground. Then pull them out slowly, as they are attached, and take careful notice to how everything is arranged. Hope that helped.Picture of gun with pin located on the side, between top and bottom chambers:http://www.pbreview.com/productpics/?product=2762&photo=5778Hence the air being disconnected.
Have a degree in chemistry. Do not put anything in your gun besides air-tool lubricant (for mechanical guns), or actual paintball lube.
No, you should use only paintball specific of air tool lubricant.
