The base of the gun doesnt effect the accuracy... but what does is from the point of contact with the paintball inside of the gun when it shoots, till the exit of the barrel.  What will also change the accuracy is the shape of the barrel, little things like holes designed so that air escapes in a certain way that may create a spin for further distance.  It may also be designed to reduse the noise by sending it more into a specific direction, if that makes any sense.  If theres more holes on the barrel, it will tend to spread the noise to make it more spread out seaming much quieter.  If there was no holes the noise has only one place to travel which is straight, meaning whoever ur shooting at will hear it the best.  Stupid details like that is the difference between a 15$ barrel and an 80$ barrel

As far as noise.  No difference..  Thats all on the mechanics of the gun itself.  I hear autocockers are the most accurate paintball guns though.

The barrel backs do effect accuracy because you can get a good paint to barrel match which is what you need for an accuarate gun. My empire barrle kit on my cocker shoots darts,and as an added benefit it is so quite that I have shot people and they didnt have a clue where it came from.For low pressure set ups you definately need a kit to get a good paint match so as to not loose to much of the available pressure due to blow by of an improper paint to barrel match.Get one and see for your self, By the way im not just a cocker fan I have 2 A-5's as well.

How does the base effect your accuracy?

Which is the only reason people buy barrel kits in the first place dave, so they can get a great paint to barrel match.  You obviously wouldn't select a back that one of your paintballs wouldn't even fit into.  This would cause breaks as you said, BUT they would be caused by a user controlled factor, which is easily eliminated by selecting the proper back for the size of the paint.  Holding your barrel back perpendicular to the ground w/the gun end threads up, the perfect paintball should fall an inch or more into it and then stop. If it falls right thru, you need a smaller back.  If it did indeed stop, it should take a little more than a little puff of air to send it shooting out the end (when done so like a spitball thru a straw) because any paintgun is going to put alot more air behind the ball than you're capable of doing for this test. 

With any barrel other than a Flatline (or maybe the Apex - don't know much about that but from what I've gathered, it's simply BT's answer to the flatline so it probably works along the same principle) this match is arguably the most important of the three critical factors that are known to improve accuracy.  The other two being a regulated power source (HPA or Palmerized CO2, & paintball quality.)  The backs, or inserts, depending on which kit you get are what give you this.

Good paint to barrel match, plus a regulated air source to minimize velocity spikes, when using a good quality paint will give you the best accuracy attainable for any given paint gun.

All paintballs are the exact same size!  exactly .689 caliber.  The only difference between paintballs is shell texture, fill color, whethere the fill has soap or not, shell softness, mass and how much paint is inside.  This fact is proven when you go to buy paintballs.  They dont ask you what kinda bore your gun is, or what kinda gun you have!  They are all the same.  Any paintball will fit any paintball gun, so obviously your making it up as you go.  Or in other words your talking out of your a**

For 1 thing if you think all paint is the same size you should quit playing this game because you obviously dont know s**t about anything including talking out YOUR A**, Do some research before sounding like a know it all fool in front of people that know what they are talking about,according to you last post, you should bury your head and never dig it up again.

Draxus Blaze .681

PMI premium .687

Game Face scorch a lot smaller than .681

Evil and Mid evil .687-.689

If I come upon you with your head buried I'm putting a boot up your A**

Lol 3 posts in a row.. throwing a little temper are we?  lol how old are u anyways?  12 prolly... you should be embarresed if your not, cause that would mean you have no excuses.

Im on this forum to help people with no sense of logic or physics, such as yourself.  Why don't you re-read the whole conversation and than look at what you have said.  You really are pathetic.

BTW ive never shopped at wal-mart.  The only place ive shopped was SAKworldpaintball.com and boston paintball.  Lol good try though.  You remind me of one of those kids who thinks money is everything.  Yet again another newby.

FYI Dave,I'm 35 and been playin paintball for almost 7 years,you want to talk about logic,hehehe, here's logic for you you can't shoot a paintball thats .687 out of a .681 barrel, and calling me a noob...dam I love that, you are the pathetic one, not knowing paintballs are different sizes from different manufactures,do yourself a favor,until you know what you are saying to other people you shouldn't bother helping them, you are only giving them false information.Don't try to be what you definately are not...an expert! And you writing prolly instead of probably...dam give me a break, is it laziness or stupidity that causes you to write like that? Don't worry about helping me,you have nothing to offer me,I can see that from the stupid things you are saying, trust me you really don't know as much as you think.Ask around about paint sizes, you'll see then you'll be educated.

Ok, I made a mistake, i didnt realize that paintballs are different sizes... but ive talked to my buddy who owns a local paintball shop.  He tells me that you can shoot a .689 caliber paintball out of a .681 chamber, because the paintballs have flex.  This is actualy benificial because it doesnt squeez out air past the paintball

So I GOT A GREAT IDEA..  DAVE HAS COME UP WITH MANY MANY ARGUMENTS OVER EVERYONES STUPID COMMENTS.  SO LETS ATTACK HIS SPELLING..  Then lets CLAP ABOUT IT!1    YEEHAAWW  then we can all watch NASCAR!

It is benificial because it creates a stronger seal around the barrel allowing less air to escape.  How would this decrease accuracy??  It doesnt send the paintball flying in a different direction!

Im sure you dont know any of this because ur just a little kid who thinks he knows everything cause hes played paintball a couple of times and own a marker.

This is the information I have been provided with!

Back to the topic,longer backs or controlled bore doesnt affect accuracy that much BUT, for low pressure setups the longer back of the pepperstik,is a big plus because it allows the marker to generate more pressure before it is released when the ball clears the back and starts into the front which is considerably bigger than the back,after the ball starts into the porting or the barrel front it starts to bleed off pressure.The longer back means more usable pressure and therefore allows you to run your regulator at lower pressure hence makes the marker more air efficient...a plus in my book,and also lower pressure means a lot quiter marker because you don't have 800-900 psi trying to blow out the bore.Another huge plus.Think in terms of a real rifle, the sound isn't from the powder burning, it's from the sound of the bullet exiting the muzzle and from the gas pressure thats built up behind the bullet, Paintballs are very similar, pressure behind the ball is what makes most of the sound,lower the pressure...lower the noise.

Got Jerk?

even when he is wrong he tells us how dumb we are. I am amazed that he didnt tell us about how he is the captain of his high school paintball team.I bet they are real contenders with him at the helm!!!

Got Jerk?  Thats a laugh.  The only one being an a*s in here is you.  I am not here unwilling to change my ways and not listen to what anyone has to say.  Instead I am here with a certain amount of knowledge and experience willing to gain more of each.  The only knowledge I have learned is that there are people like you in these forums "Darkmaster" that just like to fight and think that they know everything, and they are the authority, and when somone like me makes a comment, all you want to do is fight back.  So why dont you **edited**, calm ur as* down and grow up!

P.S.  I said i was a paintball captain once.  The reason i only said it once is because it doesn't say anything about what i know, it only shows experience and I'm the only one staying on topic by discussing the topic, and not how much experience that I have.

Now will you shutup?

Daveb333,

do a seach for "captain" and you will see that you have told us about your high school exploits THREE times. One question for you daveb333, Do you ever wonder why everyone is always giving you a hard time?. and i am not asking that to be mean i just wonder if you know. I dont like fighting with you i just thought that if i was rude you would start to wonder why everyone flames you. If you look back on your posts you do come off a little harsh. And if you look back i only attacked you for being belligerant,I have never claimed to know more than anyone else. I just dont like people being rude to others just because they pose a good point or it seems like they might be disagreeing with you. Look dave im sorry for attacking you,But do you think that you could take more care to not come off sounding so rude ?. It must get old fighting in all you posts and i dont want anyone to feel like they are not welcome here.
