I know that bolts on most semi-auto paintball guns fall into 1 of 3 classes that i am aware of.

Blow back
Stacked Blow back
Blow Forward

But is there a bolt that is 100% electronically driven?
As in air pressure is only used to expel the ball from the gun and not to move the bolt.

Cause i might be on to some thing but i am not sure if it has already been done.

its been done by purple people from the planet purple!

Stop spamming.

NPS has made something similiar to being a fully electronic gun. It uses no air source. (i'm not sure if thats what the link roadkill said).

**paintthecatBLUE** · June 5th, 10:16 AM

thats the link roadkill gave.

the evolt, it makes its own air source but the cycling operation is done by the battery and not its self generated air source, so in a sense it has an electronic bolt.

Does anyone have an evolt? If so, does it work pretty good? I was just curious about it.

**Kdrx1** · June 5th, 10:55 AM

I dont think they are out yet

***martix_agent*** · June 5th, 11:17 AM

it's have to use ahuge ass battery to supply enough power to shoot a bolt forward at 30fps and do it consistantly

**mavsfan31** · June 5th, 11:25 AM

Yea, I'm pretty sure it's not out yet.

**Mortisdeum** · June 5th, 12:51 PM

The evolt looks like it's makes it's own air but i am not sure about how the bolt works

cause i messing around with a neodymium magnet and an coil of wire and was kinda in inspired by how fast the magnet shot out of the coil with a 9v.

And it gave me an idea.

Why not combine the bolt and the solenoid in to the same unit.
One of the benefits is the gun would only use to propel the ball out the barrel and not to re-cock the bolt

**imprez55** · June 5th, 03:35 PM

that could work. i am thinking you are imagining something like a maglev (sp?) train. or you could have the air source like a cordless pnumatic nail gun. just a thought. i am not sure if that is how the evolt works or not.

Bolts tend to be made from lightweight aluminum or a plastic, neither of which is magnetic and useless to a solenoid. You could add a core or a coil to it but now you would be breaking the goal of using the light material in the first place.

Something like a Cocker isn't blow back, although it uses air (through a ram) to move the bolt around. There plenty of other guns as well that aren't blow back.

**PaintBallBob** · June 5th, 04:44 PM

the evolt still uses air but it compresses its own. I dont really see why anyone would buy one, it can only shoot 6bps. costs like $500, and the battery(which isnt a normal 9volt) only lasts for a couple hours...

Torch · June 5th, 05:00 PM

And when it comes down to it, it's still using air to fire. It just doesn't use a tank.

It's true that its rate of fire can't compete with even a cheap semi in use today, but then the first semi-auto's weren't much for speed either. It'll evolve and become smaller lighter and faster...if it survives in the market that long of course.

aluminum bolt with neodymium magnet in it's core. Light weight and a very strong magnet

I plan on having it use standard co2 or nitro tanks as the air supply.
But the operating pressure may be in the 75-150 psi range

Use a powerful solenoid witha powerful, short burst of electricity from a high power battery.

The solenoid IS the bolt.

Yep

Just bought the piping, magnetwire, magnets, ect... to start work on the prototype

**MR. Marsullus** · June 5th, 07:25 PM

the new evolt is not worth the money yet, but when that technology advances, the results should be pretty cool.

The problem is the technology is based on batteries, WHICH HAS NOT ADVANCED IN THE LAST 100 years!!

The design of the EVolt is crippled and will likely never be popular, except with police-training, and those looking for novelties.
The problem is batteries are a VERY INEFFECIENT way to store energy, unlike CO2 (or Gasoline).

As for the original poster, all paintball guns are divided into 2 main catagories:
1- Poppet-based (guns with hammers). This is divided into cocking, blowback and ramvalve.
2- Spool-based (guns without hammers). This is divided into blowforward, rambolts, etc.

Neither system can run directly from a solenoid because it requires a HUGE amount of energy... and large battery packs.
The exception is a sprinkler-based system. This is how the new mQ valve works. Instead of a poppet or spool-based system, is uses a sprinkler-valve, so it doesnt need a hammer or ram or anything.
