I have a TM 18c that I've done a bunch of upgrades on, recently I found the small metal piece that fills the hole on the back of the slide, it had fallen out last time I worked on the gun. So I took the slide apart, put it back in and reassembled the gun, but now it is not working properly. When I pull the trigger the slide doesn't move and it dumps all the gas in the magazine out the end of the barrel. Anyone have any ideas what could be happening? Here are the upgrades in case it matters:

PGC Metal Slide and Outer Barrel
GunsModify CNC Aluminum Trigger
AIP Hop Up Bucking
AIP Mag release
Guarder recoil spring and hammer
GunsModify Zero Hammer
Guarder 6.02 inner barrel
Guarder Loading Muzzle
Shooters Design Steel Full Auto Sear

I'm attaching a couple pics of the gun apart, hopefully someone can point me in the right direction.

Thanks,
DT
