    Closed Bolt Mag Idea

    I was brainstorming today at school and I thought of a way to make a closed bolt version of a mag. It would have to be electronic, and most all of the parts used in current mags could stil lbe used in this new one. Okay hear me out on this one:

    In order for it to work, you would have to do away with the sear. It wouldn't be necessary anyway, since the bolt would be closed the entire time. Now then, this would be the same as a current mag that uses the pressure of the gas to fire and close the bolt. Only, once the bolt reached the fully closed position the gas wouldn't be released, it would continue to hold off and keep the bolt closed. Another firing mechanism (valve of sometype on the powertube) would be used to release the air from the reservoir and when all of the gas pressure is gone the bolt will open. A solenoid would be used to push the valve's on/off to repressurize the reservoir and close the bolt again and start the process all over.

    So here it goes in steps-

    1. solenoid pushes the on/off, which fills the air chamber and closes the bolt.

    2. firing mechanism releases the air which fires the paintball and reopens the bolt

    The only problem is that it might have to use 2 solenoids in order to 1) toggle the on/off and 2) control the release of air from the reservoir. On the plus side, its a very simple closed bolt marker that really wouldn't be that much more difficult to make than an average mech mag. Even though closed bolt doesn't really mean that much anymore, it would still be neat to have.

    It would even be easy to put together to. If I had a milling machine, I could make make a proto of this. But, I don't, and I can't. You could make this with 2 spyder noids, a morlock board, a redesigned powertube or powertube tip, and a special rail that can house the 2 noids. That would be the only special part of the out fit. I figured that it would be too difficult to put two noids in the frame so, if you made a rail that housed the noids you could possibly upgrade a mech mag with a kit. Just remove the sear and replace the frame, rail, and powertube and you've got a closed bolt e-mag!

    Well, the idea sounds pretty cool, but maybe for the two noids' you could put them in a foregrip or something.

      I'm kinda confused about the whole part about the air holding the bolt open and all, and then a valve opens it up and returns the bolt, then air pushes it back again? How does all that happen? Are you saying have like 2 parts to the powertube, one that works as the normal power piston does, holding it against a light spring, then a valve opens and lets the air go out like the side or something? I dunno if that even made sense. Anywho a pic of all this would help greatly.

        No no no, it would work just like a normal mech mag. In a mag the air pushes the bolt closed, right? Well it would be the same thing. The only difference is, when the air pushes the bolt closed, it doesn't release the air so the bolt will just remain closed. Then, only when the air is released, by some kind of valve placed along the powertube, will the bolt reopen... just as it does on a mag. But to reach this kind of control a noid will "toggle" the valve's on/off which will control the re-closing of the bolt.

          It is clear that you have no idea what you're talking about.

                OK I'm still confused. First, how is the air not gonna vent in the foreward position anyway? The only way the bolt will be foreward is with the on off in the open position, sliding the bolt foreward. When the bolt is foreward, the air vents around it. What will keep the bolt foreward if the air supply is closed off? And then where will the air go when this valve is open?

                  That is why it will need a new powertube. If the powertube had a valve that controlled teh flow of air, then it wouldn't vent down the barrel. As for the on/off, thats why it would need a noid to control it. The electronics would control when the on/off opened and let the bolt close.

                  Maybe I'm not explaining it well enough. The automag main valve would still be the same. There would be no need to change any part of that. It would require a new powertube or somehting along the lines of that to stop the flow of air down the barrel when the bolt is in the closed position. It would need a solenoid to push the on/off and control the motion of the bolt (as well as the flow of air to the paintball). Then it would most likely need another noid to control some sort of valve that would release the air to the paintball once the bolt is closed. Is it clearer? Or is it more confusing?

                    my concern is why?

                    why would you want it to operate like that?
                    what are the benefits?
                    you make it more complicated, but do you make it better? it would more than likely be slower.

                    I've got nothing against modding a gun, trust me, but I think before you embark on any idea for a mod, you have to ask yourself"what am I really tring to acheive? is it feasible to accomplish?

                      Well it wouldn't be very practical, but if you could do it as a modification, it wuld be something cool to flash around. I wasn't recommending it as the next miracle marker. I was just throwing it out there to see what other people thought about it. See if anyone had any other ideas.

                        The problem is that there is no actual benefit of closed bolt, and the claim that it makes the ball fly more efficiently or better has been proven a myth.

                          OK but what is holding the bolt foreward if the air supply is closed? Also I think it would be cool to do a closed bolt mag just cause it's never been done, and it would drive the guys who think cockers are more accurate insane.

                            I realize there is no real benefit to closed bolt. But like ^ said, its never been done. It would just be cool to do. As for the bolt staying closed... i don't know. That thought crossed my mind. Maybe if the air wasn't held back in the powertube but in the bolt? If the mechanism that released the air to shoot the ball was in the bolt then it could still be held closed and still hold th eair back.

                              That would work, but it could be hard to do. Lemme know if you come up with a way (don't read that sarcastic, I really think it's possible)
