need help with my RT pro

[Gkelley]

I shoot a RT pro that was one year old this Christmass with a Flatline 3000 air system it is all stock inside bolt Retrovalves ect..

My problem is that several months ago i was experiencing bolt stick I cleaned the whole thing out and it continued to stick. I did a search on this forum and found out that I need to buy a spacer kit and go larger. I went up one size and it still stuck so I went up another and still the same I got all the way to the larger size when the real problem started. As soon as I turn on the gas to the gun it sounds like when a tippman is out of gas. Like a very very rapid fire and it dose not stop until I shut the gas off. I called the tech line and the guy told me it was probly the on/off pin but i forgot the size. Also what is the normal length of the pin?? Is there anything else that could be wrong with my gun other than the on/off pin??

Ps. It has been several months since I have played and my bolt has some rust spots on It what should I do??

check out http://store.airgun.com for your parts.

As for what could be wrong, I'd say follow the tech line's advice first.

havoc was helping me with some bolt stick awhile ago. it had to do with level 10, but i think it could still help. i would check the bolt bumper. that clear almost rubber peice that goes over the pt tip. if its shredded in any way, then peices can get caught between the bolt and the power tube tip. that will cause some stick.

Replace the PT o-ring with the one that came in your PT spacer kit, or one from an AGD parts kit.

Use the .225" spacer.

Replace the bolt bumper if the center of it is tearing apart.

Make sure your output pressure is 700-800psi.

Replace your bolt spring.

Use a piece of emery cloth or a scotch brite pad to clean off the rust on your bolt.

--And what is the exact lenght of a new on/off pin??

take yours out and look to see if yours is a perfect cut on the bottum (new) or if it is kinda sharp (broken)

i forget the exact sizes but at the onlyine store u can select "RT Pro pin"

Ok thanks!!

One more question why does it break or shear off and what can I do to provnet it from happening again??

[Bulldog]

Sometimes when you pull the valve out of the gun and force it, it can shear off if you didn't press the trigger first. Might be other ways too, but this happened to me a long time ago.
