om looking into buying a barrel back and not sure what size to get and help would be appriciated i have spyder threadings and cheaper is better lol blame the economy for that last remark!

also i looked this up maybe a good idea? http://www.ansgear.com/ProductDetails.asp?ProductCode=SLYBARRELBACKKITSPYGREY&click=2

thanks guys sorry for the noob qeustions

Those barrel backs are for sly barrels so you would need to buy a sly barrel as well. I would go with this - http://www.techtpaintball.com/iFIT.html - i know it is more money but would be what you need a spyder thread adapter to spyder barrel. Plus the nice thing about a kit like this is if you upgrade to a new gun that does not use spyder threads all you need to get is a new adapter and not a whole barrel kit.

Just an option.

sweet man i'll look into it for sure! thanks good idea and one ? what does it mean when an air tank is a low pressure tank?

The are three types of compressed air tanks low. mid and high pressure the difference is in how much psi the regulator will let out of the tank. I dont remember the correct amounts for each but most guns will run off a low pressure compressed air tank, but most guns like tippmanns and spyders or spyder clones need the high pressure tanks to function properly.

figures i have a spyder lol would this tank be suitable? http://www.hustlepaintball.com/ProductDetails.asp?ProductCode=30750501&click=2
