A-5 broken

I need bad help!!!  I did a full mod on my A-5, every modification you can buy except the Electric option.  Now my gun leaks air from the connection on the low pressure tube where it goes into the gun and my trigger will not release the bolt.  I pull back the bolt and then try to fire it and the trigger stays stiff and the bolt stays open. I have to take the grip off for the bolt to release.  I took out the double trigger put in the original, same issue.  Took out the new rear volocity adjuster and put the old one back in, same thing.  Checked all the o rings all in great shape.  I have a full air tank tried 2 different 92/4500 and nothing.  Took the gun apart 4 times and still the same issue.  I have greased, taken it apart over and over even said sweet things to it and it still has the same two problems.  All the internals are new mods, could one of them be faulty or is it me?

Fixed.  New rear bolt (bottom cut out, catch) wasn't cut properly for trigger to engage.  Did some grinding to make the bolt catch a bit bigger and now the trigger works fine.  Leak was fixed, low pressure velocity was to low.  Turned it up and the hissing went away.  Note:  LP kit and R/T.  You need the 1/8 hose trigger kit for RT to work properly.  The original hose's just can't supply enough air for the RT cylinder to work properly or actually at all.

Thanks for your help
