depends what your gonna be playing with it... obviously paintball... but woods or speedball or what.
if it was me id get:
motorised loader
new barrel kit
egrip
in that order. and sone air aswell if your running co2
Better barrel is a must, a flatline is good for woods but take care to set it up and even then it can be paint sensitive, Smart Parts 14-inch progressive is a pretty good all-rounder
MROF is about 9bps so you don't need a mega hopper, a revvy or a basic ricochett is fine.
Air is a worthwhile upgrade, more and more sites have air now and its so much better than CO2
Egrips - Custom Pro only (Ithink)
You could fit a red dot sght, but only if you have a barrel thet shots straight.
if you realy love it:
Double trigger
rocket cock
Most important, keep it clean, well lubed (decent marker oil) and maintained. Get hold of some sensible spares and it should look after you.
I wouldn't go any further, try a few other guns to see what you might want next.
ENJOY
