RT Expansion Chamber and double trigger

I recently installed a response trigger, expansion chamber, and a double trigger into my Tippmann 98 custom.  One thing I noticed which I have not before was that when I screw my barrel in, it pushes the bolt back slightly cocking it.  Then, when I attached gas to it, I was able to shoot but I had to recock after every shot.  It just comes to mind now that the velocity screw was still all of the way in, I'm not sure if that has anything to do with any of the problems.  When I played with the response trigger adjuster, I was able to get a rapid short burst of maybe 4 shots then it would uncock.  Everything was oiled when the gun was apart.  Also, for some reason, the safety does not seem to want to switch from fire to safe.  It will start to go a little, then completely stop around the red area of the safety.  I'm not sure if this would have anything to do with the double trigger.  Any suggestions?  any help anyone could provide would be greatly appreciated.  

the two screws that hold the valve in place are in and the bolt/barrel is stock.

yea, those skrews are loctited in, however we did have suspicions about how the ball latch looked. I will take it all apart again and reoil everything and see if that helps, Idk why thats shooting all weird, I dont remember if all the way in is really fast or really slow on the velocity adjuster. 

yeah, my friend put the ball latch in backward and it wouldnt work

i'm pretty sure the latch is in correctly, any ideas as to y the safety will not come off of fire.  it moves fine when it is disassembled, but once i asseble it, it will not come off of fire.  It seems that it willnot push in farther than the little red ring.
