Upgraded Tm G18c wont cycle properly
 
Hello! So i recently acquired a tm glock 18c with a bunch of mags. Problem is when i got it after a few mags or so it wouldnt cycle properly. It usually cycles on auto, but on semi its a load of problems:
-sometimes it makes a POP noise and nothing happens
- it half cycles back
- it lets all the gas out
- it fires and locks back, but with almost no recoil.

Jimmying around with the mag seems to cause it to fire properly with extended mags, but with short mags the problems persist no matter what.

Ive tried
- re lubing everything
- re assembling the hammer assembly and nozzle
- Putting a stronger hammer spring in it
- returning the hammer assembly to stock tm parts

heres a list of upgrades:
Guarder lower
guns modify hammer
steel valve knocker
pgc slide
150 percent recoil rod + hammer spring.

I really want to get this working properly, i spent alot of money on it, and want to lay down some glock full auto at my next game!
Thanks guys!

I think you don't install 150% hammer spring , it will be better. 150% hammer spring is too strong. When the gas power go down, it may be not enough power push slide go back. The 150 % hammer slide will stop the slide in the half cycle.

Could be a ton of problems

Interfacing of the nozzle with your mag gas route might be bad, that would explain the "jimmying" thing

Nozzle is cracked, there are good chances of that, might also explain the jimmy thing

I'll let the e-luder of this forum try tonight's this one out though

I taped the back of the mags and it helps them shoot properly, but only on some of them. The others just pop or cycle 1/4th of the way back, I'll check the nozzle

Ok so this might sound crazy, but I got the long mags to fire full kick by pushing in the feeding lip pins a little, one short mag fires fine, the other half cycles

PROBLEM SOLVED.

I bent the living shit out of the hammer spring, now she kicks like a mule
