yes, i can tell ur a noob bc u spelled "warranty" warentee. i'm no tippmann expert, but u could try the "Battery In The Foregrip" mod. i've heard thats popular. also, idk exactly what kind of tippmann u have, but i'm a big fan of the magtrig mod if its a nonelectronic gun.
magtrig is when u take two magnets and face the repelling sides toward each other and glue one to the trigger and one into where the spring goes. btw, remove the spring. u can also mill wells for the magnets. also, a dremel opens up halfbacking, lightening the gun, cutting off useless parts, etc...
before u experement, at least ask before u do dramatic stuff to the gun. but, if your gun is crap, its more fun not to ask and make up your own mods. have fun. oh, if u are a member at bj's, get a dremel there. its only 20 bucks and is soooooooo sweet.
Just start off with some custom "milling", the only tools you'll need is a hacksaw and a file (I'm sure you could get both for under 15$). Tippmanns have a **** load of extra metal on them (which is very weak and easy to work with) so they are nice to work on if your are just getting into modifying your guns. You could do things such as; remove the "tippmann" letting, cutting the rear site off, removeing the finger grooves from the front foregrip, removing the foregrip entirely, remove the site rail, remove the "push safe/fire". Just sit down, look at your gun and say: "how can I make this ugly thing look a bit nicer".
