the ASA (air source adapter)
A vertical adapter is what connects the air from the ASA (Air Source Adapter) to the proper places (the valve or any other parts controlled by air) This is where you can put a gas through grip, expansion chamber, regulator or anything that has the standard ASA threads and is attached to the ASA (horizontal/tank adapter)
the ASA or Air Source Adapter is the part that connects the Co2/CPA tank to the gun, usually via macroline, and is usually found on the bottom of the grip. an on/off ASA is one that can be turned on and off, to make changing tanks easier.
the ASA (air source adaptor) can typically be swapped out for a aftermarket one, there are a few markers out there that the ASA is also the regulator for the marker and these can not be changed out typically
Well,you need some sort of air source. An air compressor will do. Or a Co cartridge as used by paintball guns, together with an appropriate adapter.
The very basics are: a certified paintball mask, a paintball gun, paintballs, and a propellant source (co2, HPA).
The "tombstone" is what the gas-valve connection device on the Tippmann A5/X7. It is on the end of the steel hose, which is connected to the ASA or Air source adapter, where the tank is screwed in.
Air is the source of power for the paintball marker. It is the pressure that moves all of the internal parts (unless electrical) and physically moves the paintball out of the barrel.
Yes, all brand paintball guns use a tank or other source of pressure.
Most likely the O-ring is broken on your tank valve. It is a small circular yellow-clear ring at the top that seals the valve into the Air source adapter. just take the old one off and put on a new one.
The fluid, high pressure co2 (or HPA) is let into the gun when the tank is screwed into the Air Source Adapter, it is then stored in the valve, until the valve is opened, then it pushes the paintball out of the barrel when it expands. At the same time, it resets the springs and mechanical components (specifics depend on the gun model) , as the valve shuts and the gun gets ready to fire again.
Accuracy is a measure of how close to an absolute standard a measurement is made, while precision is a measure of the resolution of the measurement. Accuracy is calibration, and inaccuracy is systematic error. Precision, again, is resolution, and is a source of random error.
