[ghost flanker]

I stand corrected on the shims.

Thank You ghost flanker!! I followed your steps Saturday and my son played with it all day Sunday at Fox Paintball. The gun performed flawlessly. "Of course it works-its AGD". Thanks again for everyone's help!

You're welcome! Happy to help.

Glad you got it fixed! All the love, all the help, all the great advice. The mag community is great.
I haven't been able to get out to the field for awhile so I would have missed you.
I do like that more mags are populating at Fox.

im having the same issue. Mag will hold air but not fire. This is all of a sudden, the marker was shooting.i have adjusted velocity both ways with no change. I have also removed and replaced bolt with no change. My tank output pressure is 750psi. When i remove bolt and replace it in the ule with out the red spring and bolt upon gassing up the marker it just leaks straght out the barrel. I have oiled the marker up removed the 2 orings under the on/off and reoiled no change.

I have no parts to swap. What do i need to order from sandman?

Did you check to see if your bolt spring is damaged?

more info please. level 7 or 10 bolt, what on off. also check your body alignment to the valve. it could be that they are not straight with each other and the bolt is binding up.

When you gas up without the bolt, make sure you are holding the trigger in, or it will just vent out the front. If you are holding the trigger and it is leaking vigorously out the front, and it is determined that the two on-off orings are not bad, then one of your orings in the back is bad. It is most likely the Regulator Valve Pin O-Ring at the back of the regulator pin assembly. A leak at that oring would allow air to flow through the valve and into the front chamber, and if the bolt was not in place, right out the front.
