Yes. If you keep firing your gun without any lubrication, the O rings will eventually wear down and your gun will leak or cease to function.
No, paintballs are biodegradable.
any .68 caliber will work, really though go to a paintball shop, anything from a store that is not paintball specific will be pretty bad paint that has been sitting there for months
No, it is a decent marker with quality parts.
It would be a good idea, i do after a bad experience.
In general you can expect a paintball to sting (comparative to a thick rubber band snap to the back of the neck, but wherever you are hit), as they're normally shot at around 300 ft/ sec. Without clothes, paintballs will generally leave a welt.
fire service is a fire burning bad
extra cost all Delta forces guns are really bad
Fire,. It's bad.
Generally it is bad to leave batteries in anything battery operated for long periods of time. I have ruined more than one useful thing because I left batteries in until they started to corrode. In the case of paintball guns, leaving batteries in is essentially the same as leaving a low grade weapon around for anyone to use or misuse. You can do damage with an improperly handled paintball gun.
No, besides being expensive, the X7 has a very high rate of fire, two things that are very bad for new players. This will take a lot of money to run as a starter marker, which is the main causes of people stopping playing.
The tree catches fire and it dies.
