I've had it a few months, and just rebuilt all of the orings in the gun wit my own orings ( not the ones from eclipse ) and am just wondering how long it will take to break in as the bolt is berily moving with around 600 psi in my empty steely tank just wondering if this is normal? Lmk ASAP please if u now of this

It could be not enough pressure in the tank. The other thing it could be is the bolt sail oring. The rearmost oring. Try a different new one and see what you get.

My money is on not enough pressure though

and we know how accurate those gauges are.

Well, to begin with you said "with your own o-rings". Note that some o-rings follow standard sizing (013 for example), and some are metric (14x2 on prop). So there's the potential you have the wrong o-rings on now.

I would also be willing to bet that because of the 'empty steely' you are using that there isn't enough air getting to the marker.

Basically: double check to make sure you are using the right size o-rings, they are greased properly, and fill your tank. If you have a non-store brand battery, I'd get one of the better duracells/energizers too

EDIT: Oh and to answer your question about break in.. I normally recommend about 10 cases before I consider a marker broken in
