Okay so I read that an eye helps not chop paintballs in half. I'm not having this problem with my brass eagle avenger, does it have an eye, and do you need an eye on a semi-auto paintball gun? Also what upgrades can I buy for a BE avenger straight out of the box, what loader should I get (nothing fancy, MY eyes work fine I just need it to drop paintballs into the gun without having to attack the loader with scotch tape)? Is there a really good 100-300 dollar gun I should invest in? And finally, how do I take it apart? Do I need to clean it, and if so how should I do that?
