The T-board does fit in the marker like Ninja said and is probably aside from a new barrel and possibly a better inline regulator the only thing you should need for the gun. The board itself comes with a lighter switch, comes stock with eyes to prevent chopping, and will help raise up your ROF dramatically.

Other than that I say the best possible upgrade would be a new marker when the time comes. Save the money you would use to build this marker and move up the ladder when you are ready.

kool thanks everybody.

but what barrel, a whisper, empire, what? what would be best for my gun?

Freak Junior, cheap and expandable

u like freak alot don't u?

I recommend it cause its a cheap barrel thats easy to expand, personally I love Dye ultralites.

You really only need a few inserts for the kit anyway

i have a freak jr on my cocker with a all american front, and the inserts that come with it is really usually all ull need, but they r accurate, buy one, nd for ur gun u should also get a drop, an electronic hopper, and that t-board thing like ninja sed nd a reg like the ans ones they r the best

like i said before...i am a beginer just getting into paintball. I know what a drop is but how does it help your gun?
