    RT bad paint?

    i just had my RT adjusted, as it is breaking in and seemed to shoot fine dry firing it... then i aired it up a few days later and put sum paint in it and it shot for maybe 50 shots walking it fine.......then it stopped..... i manually reset the bolt and it fired 2 shopts and needed to b reset again...... i checked the paint and it was bad.... all soft.......but i gave up after that cuz i had no other paint....... with the smallest carrier and spring would bad paint cause this to happen?

        Sounds like bolt stick caused by a carrier that is too tight. Can you use a larger carrier without it leaking? Of course, you should remove all shims when checking this to avoid leakage caused by too many shims.
        Except for the Automag in front, its usually the man behind the equipment that counts.

            If it goes full auto just by putting in a larger carrier, then you have other problems as well. The carrier only allows the powertube o-ring to be adjusted to provide the exact required fit on the bolt stem.

            If the gun is going full auto with a larger carrier, then I would check the small on-off top oring as well as the on-off pin for damage.

              the guys at destructive customs played with it and said it was just breaking in and needed smallest spring 2 shims and smallest carrier.......and i dont see any damage to anything...........

                I hate to disagree with someone who is physically working on the gun, but a full auto condition does not happen when the carrier is too tight. A carrier that is too tight causes bolt stick.

                Here is a list items in a level 10 and how they affect operation:

                <B>bolt spring</B> - provides force against the bolt. The pressure force in the chamber minus the spring force on the bolt results in the impact force that the ball sees. A stiffer spring means less force on the ball. It may also mean that you have to turn the chamber pressure up to overcome the spring force. Increasing the chamber pressure to allow the gun to fire in this case will result in a higher velocity. Thus, a longer bolt spring also results in a higher operating velocity.

                carrier oring - seals between the bolt and the chamber. A damaged carrier oring will leak and causes many to use a tighter carrier to compensate. This causes bolt stick isuues.

                carrier - Helps resize the carrier oring. The carrier orings are not all created exactly the same so due to the tolerance requirements of the level 10, we must artificially change the oring size. Using different diameter carriers, we can make the carrier oring tighter as required. The ideal tension allows the carrier and oring to easily slide along the bolt stem, but not so easy that it will move on its own when placed vertically.

                bolt vent hole - when bolt sits at rest, the vent hole in the stem is slightly inside the chamber behind the carrier oring. Any forward movement will expose the vent hole and some of the air in the chamber will escape. This happens slowly compared to the firing action of the gun and under normal conditions the bolt goes forward and the air is allowed to rush out the powertube in a normal fashion to fire the ball. If the gun is fired and the bolt hits and object that it cannot move, the vent hole will be exposed by the forward motion and air will escape until the force of the chamber pressure is less than the force of the bolt spring. At that moment, the spring will push the bolt back and the gun will reset.

                shims - shims determine how far forward the bolt has to go before the vent hole is exposed allowing the air to escape and the bolt to reset. Too many shims, will cause the vent hole to be exposed and a slight leak will appear. Many people compensate by using a tighter carrier which squeezes the oring over the hole. This mistake causes many to use a carrier that is too tight and causes bolt stick problems.

                sear - the sear holds the bolt back against the valve. When you pull the trigger, you rock the sear assembly, which closes the valve on-off and then releases the bolt. The sear stays out of the way until the bolt completely resets. Once the bolt is completely back, the on-off pin pushes the sear assembly back into place and releases the air back into the front chamber. If the sear is worn at the tip, it can slip when resetting. This may cause a full auto effect.

                on-off pin - The on-off pin shuts the air off from the front of the valve. This keeps the air from gushing out the front of the valve when the bolt is forward. It also provides the force to reset the sear after the bolt returns. If the on-off pin is too short, the valve may release air too soon, which may cause the bolt to not completely reset due to air pressure holding it forward and may even cause enough pressure to be released to refire the gun. this would cause the full auto action if it happened everytime the bolt returned.

                  so u think it has sumthing to do with the on/off?

                    the sear is not moving all the way if that means anything......it is possible to manually move it up 2mm's to where it would push the pin up pretty far........ and the pin assembly/o-ring are all fine

                      The trigger rod will be limp when the bolt sticks. The bolt being forward will prevent the sear from resetting. Thats normal.

                      How old is your RT? What style is it? Is it a Classic RT or a Retro Pro?

                      If the RT has any age to it, I would bet on the sear tip being worn a bit rather than the on-off causing problems. When you checked it, was the part that holds the bolt shiney at the tip? If there is even a tiny indentation where the bolt touches it, or if the tip is even a slight bit rounded, it may cause full auto problems.

                      As for the carrier sizing, take you carrier out and test fit it on you bolt. With the bolt sitting stem up, it should slide on gently with a bit of resistence. If you have to force it on, it is too tight. If it slides down the bolt stem on its own, its too loose. Adjust the carrier size until you find the correct fit. Install it without any shims.

                          You aren't missing an oring are you? Or maybe the rail bushing?

                            i just tried testing the carrier again and it seemd to be too tight......but as i have no air i cant check my tuning effects.......
