TM g18c weird cycle problem

[RiskiestLizard]

So recently my stock marui g18c has stopped cycling on full auto. on semi it works fine and chrono's right around 300, where it always has. When i put it on full auto with an empty mag in and hold down the slide release it will rattle off all the gas in the mag with no issues at all, but as soon as i put bbs in the mag it wont cycle. it wont cock the hammer or load another bb, it just fires the one in the chamber, with the VERY occasional second shot and stops. On semi it works just fine... i have taken apart the slide and i cant see anything that is obviously snapped.... help?

How old is your pistol? how long ago has the problem started? Are there any modded parts to your gun such as different hoppup and how long ago did you swap them?

Sorry, can clarify something? "Rattle off the gas"? Are you implying that there's a moving part that's broken or that the gas is being released by a moving part when releasing the slide?

[RiskiestLizard]

The pistol is completely stock there are no modifications at all. I bought the pistol brand new on the 9th of September so its about 5 months old. and by rattle off all the gas i mean that it will: fire, the slide will blow back, the hammer will cock, the slide will return, and the gun will fire. basically the pistol will do exactly what it was designed to do on full auto until the magazine is out of green gas.

There is no rattle and the mags dont leak at all. The problem began about 3 weeks to a month ago, i have fielded the pistol 3 times after i first noticed the issue

Same thing happend with my cousins glock 18 is there anything odd on the hammer rotor

[RiskiestLizard]

SOO... I think my hammer rotor is missing completely.... ill upload a pic of my hammer group so someone can confirm but i think there should be a piece attached to the side of the hammer itself correct?

[Handsonic]

How does a hammer rotor go missing? Did you put the gun in the wash and then pull it out and the rotor wasn't there like a missing sock?

[ox56]

Maybe its in the slide? Cause i highly doubt it would come out untill you take the slide off

[RiskiestLizard]

honestly i have no idea... i have had the slide off a few times for routine lubing. the rotor is not anywhere around the bench. unless its in the back of my car or smushed into the ground at my local field. thanks for the help ppl i would not have thought to look at the hammer itself let alone thinking a part would just fall off

[ox56]

Are you meaning on the hammer or on the side of the housing indiana cause that seems a little vague

yea i removed that one before taking the picture. i know what arm spring combo u are referring to.

If i knew where to find a replacement i would help but i can only seem to find parts for a glock 17 unless you go we and they dont work together

[RiskiestLizard]

i can find them for "marui g series" is there a rotor on the g17 as well. if so are they the same?

[ox56]

Not even close the glock 17 is a solid wheel where as the 18c is an oblong shape
