new toy

muahahahahahh!!!

these things are so damn fun!




level ten on the way for it, worked just fine as soon as I assembled it. Low on air now so I need to get a fill. I had the old lawn sprinkler going, but that just may have been low air pressure. I'll find out when I get back.

Congrats!

I think I've had to talk myself out of every one that has been on ebay for the last year.

A new oring didn't help, still got lawn sprinkler. I notice that the on /off pin has been shaved. Is this likely the problem?

On another note, my rtpro doesn't want to RT. Its got all fresh orings in it, and it RT'd like crazy for the first few minutes after the rebuild. Now it won't at all, and if I try to lightly pull the trigger about 30% of the time I will get a soft trigger. It sort of chuffs and then I have to pull the trigger fully to get a reset. It was like tis before the rebuild as well.

Shaved on/off could cause this.

This gets me thinking we could get a nice south/central ontario Mag game, theres enough of us around. And we probably all have at least 2 mags, so we can always bring a friend

nice shooter though. Hope you get the kinks out of it soon enough.

That would be a fun time.
I guess I'd have to bring 9 friends with me or just switch up all day long so none of my Mags would feel neglected..

Man, I have to talk myself out of every one I see. Classic RTs are my favorite markers if all time!

Could be either a worn sear or if the pin is sheared that will do it.

The stock on/off pin should be .750". A good sear will sometimes tolerate short pins in the neighborhood of .700", depending on the thicknesses on the rail, body, etc. Less than that gets iffy quickly.

For RT'ing, I check four places in the valve. The top on/off o-ring needs/likes to be relatively fresh urethane. Teflon tends to be too stiff. The on/off body o-ring can be dry or old, making the pin movement stiff (an easy check with your fingers). The reg pin and o-rings need to be in good shape; that action/flow is where the RT kick is coming from. Last, the reg piston should be free to move. A lot of people replace their o-ring, but never clean out the five years of oil residue on the cylinder walls. Slick that puppy up!

I usually push all that around with my fingers to see that it is smooth running.

When you check the sear tip, check the sides for rub marks on the rail and check the movement on the pin.

Just treat it like the little race engine it is.

Replace the on/off top oring(s).

A fresh oring is tighter than the old ones you replaced on the RT pro. Unless you have changed the on/off pin to a longer one, once you break in the new oring it should start RTing more you. If you dont want to wait for that, take that on/off top and on/off middle oring, and put them on an allen wrench to loosen them up some. Be generous with the lube also.
