NOTHING... This gun is sweet there is no upgrades this gun matches to many other good gun high class out there prople just wont buy it because its a spyder spyders are good guns people just dont like them because theree super old guns... But this gun aint old or old parts its amazin
ya i bought an ion over this too cuz this gun has no eyes and they have new boards comign for the ion and i had a spyder and it sucked it had so many problems i prolly fixed the thing about 10 times and i finally got tired and sold it
This spyder is almost the same price with the ion ( ions are high end markers spyder are not) I would rather use a high end marker, and use a low end marker as a back up. So basicly I too would rather get an ion then an other spyder because the ion is a high-end marker.
lol is all good if spyders aren't as good as ions they're better. first gun i've ever gotten was a spyder aggressor xt like 3-4 years ago sumptin like that the only thing i had to do to it was change the o-ring in the barrel, i've dropped it, throwed it, hell i've even TRIED breaking it but its a monster.
