High Pressure Air
explanation: CO2 has several issues with its usage. In the bottle, CO2 is a liquid. When you shoot, CO2 has to convert to a gas. This conversion causes the CO2 to get cold. If you shoot a lot in a short period of time, the CO2 bottle can get cold, and this can cause the output pressure to drop (as you chill a gas, the pressure drops). This also means that using CO2 in colder weather (40 or 50 degrees Fahrenheit or colder) is likely to compound this issue. You may get misfires, your cyclone may fail to feed, you may chop. As the tank warms up, the pressure rises again, and your overall shot to shot consistency can vary greatly, affecting your accuracy. Furthermore, when the CO2 gets extremely cold, it can cause the internal platic parts of the X7 to become brittle and possibly break. Specifically the stock power tube.
HPA uses normal atmosphere, which is mostly nitrogen. When pumped into an HPA tank, nitrogen does not convert to a liquid but remains a gas. Therefore, when you shoot using HPA, you don't have a liquid converting to a gas that causes the temperature to drop. Your presure is much more consistent, and you're not going to be as affected by cold weather.
benefits: huge improvement in air pressure consistency and shot to shot consistency, yeilding a huge improvement in accuracy. X7 can operate reliably in colder temperatures (note paint gets brittle when cold and may still be an issue requiring special cold weather paint). Don't have to worry about power tube getting cold, brittle, and cracking.
Considerations:
A) Before you convert to HPA, make sure your field can refill HPA tanks. Also find out if they can fill to 3,000 psi or 4,500 psi. If they can only fill up to 3,000, then getting a 4,500 tank may be wasted money.
B) HPA tanks must be hydro tested every few years. You may be able to get this done through your local paintball store or field, but it will take some time and cost you some money. If you buy a tank, especially a used tank, make sure it has a couple years left before it needs a hydro test.
C) Also, you can mount some HPA tanks on your ASA and use it like a stock, just like a CO2 bottle. However, this only works up to certain sizes and weights. A 68 cubic inch HPA tank is about the maximum size HPA tank that most people can mount on their ASA and still use as a buttstock. Anything bigger than that, and it becomes too unweildly.
D) Also, some HPA tanks are steel and some are carbon fiber. Carbon fiber is a lot lighter than steel, but its also a lot more expensive.
E) there are two types of HPA tanks: "high pressure" and "low pressure". this refers to what pressure the tank regulator puts out to your marker. High is ~800 psi. Low is ~400 psi. Your X7 needs aboutj 800 PSI, so when you purchase an HPA tank, make sure it is a "High Pressure" output.
F) Safety: Do NOT put oil into the fill valve of an HPA tank. The tank can explode. Seriously.
Hpa Safety!!!
It's perfectly fine to put oil into the ASA and dry fire some shots to get some oil into your marker. But don't put oil on your HPA fill valve. If you don't know which valve is the fill valve, just dont put oil on any parts of your HPA tank. HPA tanks are extremely safe. Just treat them right and you'll be fine.
Costs:
tank: varies. options such as 4,500 versus 3,000 PSI, carbon fiber versus steel, can make a huge difference in price. There are also many different sizes of HPA tanks, from 44 up to 110 cubic inches. the 68 cubic inch tank seems to be the standard size since it can fit on the ASA and still be used as a buttstock. a 68 ci, 4,500 PSI, high pressure tank may go for around $200.
The size of your tank (in cubic inches) and the pressure of your tank (3,000 or 4,500 PSI), determines how many shots you will get out of your tank before you need a refill. There is an online shot calculator here:
Paintball Shots
You should be able to expect approximately that a
3,000 PSI tank will deliver 10 shots per cubic inch
4,500 PSI tank will deliver 15 shots per cubic inch
before needing more air.
A 68ci, 4,500 PSI tank should give you approximately 1000 to 1100 shots per fill.
