TM Glock 18 - Problems, please help

Recommended Posts

Hi Everyone,

 

Having some problems with my G18 that I hope you good folk can help me with.

 

Gun was previously working fine and I recently stripped the gun down to clean it. Put it all back together and went to test fire. When I cocked the slide back to load the first round, the BB came rolling out the end of the barrel, I knew I had cleared the gun before taking it apart but thought nothing of it. Went to fire the first round and the side cycles back  just fine but again the BB comes rolling out the end of the barrel. Here are some of the troubleshooting that I have done so far:

 

  • Disassembled the gun and applied silicone oil to the blowback housing unit
  • Took the hop up unit apart to check for blockages and put back together
  • Tried several different mags

 

Frustrating beyond belief but hoping someone on here has had a similar issue and identified the problem. Thanks

The bb’s only normally roll out if it’s double feeding, is it, or is just one bb rolling out and it’s not firing at all?

Hi @rocketdogbert

 

No double feeding issues, just a single bb rolling out when the gun cycles.

 

When I first load the magazine into the pistol and rack the slide to chamber a round, that particular bb comes rolling out the end of the barrel as well as each subsequent shot.

 

And thanks for coming to the rescue (hopefully), the issue is driving me mad!

Take the inner barrel out and see if bb’s roll straight through the hop.

if they do, obviously a hop issue

sorry slight hijack here
@Markuz is this similar to the issue you were having Saturday with your G18 or was it just gas in the mag leaking in the end?

@rocketdogbert - BB's rolling out the barrel with the hop up all the way off,. Progressively turning the hop up wheel and it takes at least 50% of the travel before the BB will rest at the end of the barrel. Should i consider picking up another hop up bucking?

Yes, new bucking is deffo a start, can you borrow a known working barrel & hop set, and see if that completely solves the issue?

Sounds exactly like what happened to my glock.  Try checking the following....

 

When the slide is off look at the inner barrel. It simply rests against another part in the middle of the gun. Sorry I don't know the terminology. Anyway, I noticed mine was angled down slightly. So I made sure it was horizontal when I put the slide back on. 

 

Hey presto it worked.
