This puzzles me:

Why are there not mechanically operated paintball guns? Yeah, there's that response trigger thing, but that blows more gas then a fat man. Why doesn't any company just copy the design of a simple blow-back submachine gun? I mean it does kind of have a blow-back design already, but why not make the trigger mechanism the same? It'd be very easy. I personally modified my M98 so that the seer pin slips, however the rate of fire was so fast it couldn't chamber a round. This reminds me of when you're messing around with semi-auto rifles and push down the seer pin, but the hammer rides the bolt forward and doesn't strike the firering pin with enough force to set off the next round. However, if you were to get something to delay it by maybe a quarter second, it'd work. That delay could easily be made a la properly functioning trigger and seer. It'd be extremely easy, and I could do it myself if I had a machine shop.

Tippmann should definately look into this, it'd be extremely easy.

Also, I made this thing that bolts around the gun and has this crank kind of thing that the charging handle bumps into when it goes back and forth. A nut on it can vary the resistence, and when adjusted properly it delays it just enough so that it firers automatically.

I'm not talking about paintball feilds with those big inflatable things, I think that kind of stuff is dumb(no offense intended). I play in the woods and on the beach and stuff.

But illegal? 

Also, aren't there those paintball feilds called like "war games" or something, where they're set in the woods with bunkers and they don't care about velocity or automatic fire?

high velocity + automatic fire =lawsuits, bad points for out sport, and perhaps banning of personal markers.......funny how 1+1 can equil three......

damn, when i finally figure out what 1+1 ='s        people go and change it around on me!

"high velocity + automatic fire =lawsuits"

No, I believe 1000 fps is when it counts as a "fire arm". Besides, if you can fire it at people in semi-auto, automatic won't matter. And also, if that were true, what about the electronically operated automatic guns? I know it's not true automatic, but still.

It's probably a state or city thing for where you live.

But seriously, I think I remember reading that 1000fps is the cut off.

Mechical full auto is relatively complicated.  Mechanical SELECT FIRE capability is quite complicated.

Electro full auto and select fire is cheap and easy, which is why most electros have full auto capability.

There is a very limited market for full auto only guns - hence the F/A and SMG are both out of production.  There is a significant market for select fire guns - hence most electros have select fire.

The real issue is select fire.  As long as most fields prohibit full auto, very few people will buy a gun that cannot shoot semi.

And, BTW, not all fields prohibit full auto.  I have played both indoor and outdoor fields with no restrictions on modes whatsoever.  Velocity restriction, yes, but not modes.  And I can vouch for the psychological effect of an A-5 with stubby barrel shooting full auto in a confined space.   :)

Yeah I've played on feilds that where they don't care about automatic fire.

And I have to tell you though, select fire isn't anything hard at all. Actually, if you didn't mind full-auto only, it'd be easier to make than semi-auto, because you could if that were the case you wouldn't need a seer pin. But seriously, select fire wouldnt be that big of a deal. On safe, the firering pin(or in this case bolt-need valve thing) is blocked, put it on semi-auto, and the seer pin is there. More it a step farther, and the seer is now out of the way, and you can fire full auto. I'll have to find a schematic for the trigger housing of a grease gun or something. 

ALSO!!!

Why are all semi-automatic paintball guns blow-back? Why isn't there a gas operated gun that has a piston to unlock the bolt and open up the breech for the next round? That'd be more gas effecient than a blow-back. Also, why are there holes in some of the paintball barrels? While it quiets it, the gas behind the ball is dispursed, and you loose alot of energy. Why is this?

There are plenty of mech guns that aren't blowback.  Autocockers and Automags come to mind.  Blowback is just a simple and cheap design.

If you have a great idea, go ahead and make it - there will be a market for you.

The holes in the barrels are to allow gradual dissipation of the air pressure, which helps with accuracy.

How is that? I guess because of the lack of rifling.

So why not have a rifled barrel?

Hell, why not make smaller, bullet shaped paintballs that fire out of a rifled barrel?

Other then the fact that the market is already mass producing the .68 cal balls...

If you run some searches, you will find the answers to all those questions and more...

"do i have to go over this again, it doesnt matter how much air pressure is in it, and how fast it goes, if it runs on air, its an air gun, theyre called FIRE arms because of the propellent is set on FIRE and causes gasses to exspand and force the projectile out of the muzzil, no matter how fast it goes i dont care if its 534,532,532,452,345fps, unless it uses some form of FIRE to propell it, its not a FIRE arm, if it uses air, its and air gun"

My thoughts exactly, however I do recall seeing/hearing about a 1000 fps projectile limit before it's considered a "weapon".

"also, a company won't make a mech full-auto marker just because 1 field allows full-auto. "

Yes, which is why you would have a select fire switch/lever to toggle between semi- and fully-automatic.

I stand corrected.

^^^^   Those I knew about - but with the ATS guns, I will refer back to my "complicated" note.

well in that case wouldn't the c3 be a "firearm"?

I can absolutely see the FPS limitations, that's a no-brainer. The thing that gets me is that they while feilds may not allow automatic fire (too "scary"?), they still make that option for playing in the woods on electronic guns. I'm asking why not do the same thing through a mechanical action as opposed to an electron one.

Also, since you know a great deal about paintballguns, I don't under stand why barrels have the ports on in. Someone told me that it allows the air to be moved out of the way more rapidly, but once the painball gets beyond that first set of ports, all gas pressure behind the round would dissipate. Or is it that the gas pressure realeased behind with each round is not enough to want to actually expand all the way behind the ball inside the barrel until it pushes it out? Kind of like it just fizzles out and there's not enough pressure realeased. It feels like what I said is confusing, so I'll use an example: If you took a .22 SR round and put an 6 foot long sniper barrel on it, you'll actually get far less range then you would say a 3 foot long barrel simply because the gas burns as much as it can, and cant expand any farther, so after that point the barrel just acts as friction on the bullet and slows it down. I'm saying the same thing about paintball barrels. Once the gas is blown out the side, you'd think that the barrel is just putting unneccary friction on the ball.

"Once the gas is blown out the side, you'd think that the barrel is just putting unneccary friction on the ball."-Destroy Boy

It is, but I don't think that the purpose of porting, and I don't think it does, let out all of the air. It simply releases some of the pressure behind the paintball. The reason is simple. If your paintball stops accelerating very fast then it will loose more accuracy then if you were to cause a slow decrease in acceleration. At least thats what I've been led to belive.

That's a bit bold and generalized...  Many cities, towns, and other municipalities consider ANY airgun a "firearm" for purposes of their local ordinances - generally the kind of ordinance that prohibits the firing thereof within city limits.  These ordinances generally don't specify full auto, but just prohibit firearm use entirely.

Yeah some city's specifically rule out any kind of air guns. I'd know, where I used to live, a friend of mine had the police come out in the middle of the woods and to stop him and his father from playing paintball.

He said they had their weapons drawn, but this kid tended to stretch things a bit.

I looked up my local ordinance http://www.townofbrookfield.com/Documents/Ordinances/Muni_Code.htm - here - Sec. 9.02.  While it calls them "weapons" instead of "firearms", airguns are clearly regulated the same as guns in my little town.  I'm sure if I looked harder I could find a town that just lumped them into "guns" or "firearms".

Consider this, if an airgun was considered a firearm, attacking someone who isn't playing wouldn't just be assault, it would at the very least, be considered 'assault with a deadly weapon', since the legal definition of deadly wepon specifically includes 'firearm'.

You should stop dispensing legal advice now.
