Ok so just starting paintball and decided to get a G3 as my first marker, but i have a few questions:
1.) It says the operating PSI is 180. Does that mean i need low pressure HPA? Will high presure HPA effect it?
2.) What size bore does it have? How does bore size effect which barrel i use and can you change the bore size on the gun?

Gotta understand im new and don't know much yet.

edit: yes i just realized i put an "s" in marker for the thread title

The G3 is a fabulous gun. You can't go wrong. As for the psi, that just means thahts how much pressure the reg is putting out. You can use a HP tank. LP is for angels. As for bore. I'm not quite sure what the bore size is on the barrel. But I'm guessing .689. If you want to change the bore you will have to buy a different barrel.

Underbore- More efficient, more accurate.

Overbore- More air, ok accuracy.

Hope this helps and welcome to paintball and techpb.

No, the bore is actually .690

The G3 has Autococker threads, which means you can go to any paintball site and buy a barrel that is labeled "Autococker" or just "Cocker" and it fit fine. The G3's breach is not bored (Well i guess it is, but for intents and purposes, its not), but the barrels you buy are. Im pretty sure the G3's stock barrel is bored at .690, which is a fairly large bore. The more humid your climate is, you're going to need a larger bore, as paintballs tend to swell in humidity. So if you live down south/ on a coast, you might want to keep a .690 bore, but if you live in a dryer area, you might want to downsize to the .680 - .685 ballpark.

It's been proven by Punkworks that underboring does not increase accuracy directly, it just makes it more consistent and more efficient.

ahhhhh consistent was the word I was looking for not accurate. haha thanks.

Ah, okay that makes more sense, and you're welcome. I really do wish there was a way to make paintballs more accurate. But until then, I'll just have to be a sneaky bastard and be quiet and sneak up behind them.

yeah lol. it was hard for me to do that with my old marker because it was baby blue with a sliver barrel. lol

[TK-421]

Hehe, mine is green and black. Might be trading it for an entirely black G3 SE.

G3 is an awesome marker and you can't go wrong with it.

Bore size depends on your paint. Try to get a barrel kit so you can easily change bore size whenever necessary!

[gummbiii]

so if i wanted to go with an after market barrel would the .690 bore size effect my choices or could i just go with any barrel? i looked at alot of barrels that are regarded highly and they seem like their only made for specifics. for example all the jj ceramics i could find were either made for tippmann or spyder or another specific brand. if i wanted a jj ceramic would any of these fit?

The .690 bore size does not affect which barrels you can get. The Autococker (AKA Cocker) barrel threading is what affects what barrel you can get. And you can also get adapters so you can fit different barrel threads onto your G3.

so if i understand this correctly the stock bore can only accept cocker threads but changing the bore would change the type of barrels i could have right?

[TK-421]

No. The bore has nothing to do with what barrel you can get. Forget about the bore for now. If you want to get a new barrel, that barrel has to have autococker threads on it.

lol ok im just gonna focus on buying the gun for now, forget about bores, and just make sure my paint to barrel match is good

[TK-421]

I'd say just stick with your stock barrel for now, it works just fine. Then get an autococker threaded freak back with an all american front and a freak insert kit. Then you'll have the right barrel threads and all the inserts you'd need.

def get the g3 very nice started gun i have a slg 09 ul and i want a g3 now just cuz it comes with everything u need except psp3 on the board

The threads or barrel ID refer to the style of the threads on the back of the barrel, in your case, you would get Autococker or A/C threaded barrels, nothing else would work (unless you had an adaptor). Now that you know what threads you need to get, there are a few other factors that differentiate barrels from eachother: Bore size (the diameter of the inside of the barrel), Length (14" is the most common and proven to be the most practical), and brand. I suggest that you get a Custom Products 1 piece, 14", .685 barrel if you have a low budget. If you have a higher budget ($50+) then I suggest you get a Custom Products 2 piece barrel, a .682 back, and a 14" total length front.
