ksc glock 18c jamming on full auto
 

my kcs glock 18c is jamming on full auto and leaking all the propane.
i have checked and it is well oiled and i replaced the recoil spring, but it still jam's. the proplem seems to be part 22 on the manual i have no idea what its called, but its locking up when the slide returns. i am not having this problem on single fire .

and for those people who will just reply ( then only use it on single fire)

i say it has the function the go full auto i want the gun to function properly
i didn't pay $300 for a gun that dosen't work right.

thanks for any help guys

Kinda sounds to me that it's not getting enuff propellent in full auto. Does it have the metal slide and if so the magazines have the hi flow valves ? Also $300 sounds very high for that GBB.

Actually thats not a very high price in Canadian terms. Airsoft up here is minimum two and a half times more here than stateside depending on what gun.

Could be the result of rapid cool down. What temperatures are you using this gun in? Also, yo usay it's well oiled but make sure to oil the firing pin (the thing that links the hammer to the mag's release valve) well and work it in. It often gets overlooked and sticks forward, causing the gas release.

I knew it was higher up there but didn't realize it's that much higher.

yes i have a metal slide and do i need to buy the high flow vlave or do the mag's come with them

If it came with the metal slide it should have a hi flow valve pre installed. At least the ones I have bought came that way. If it still wants to act up take it to a gun doc. They usually don't charge to look at it. I have the KSC G23F and I've never had problems with full auto mode.

Off-topic but one of my KSC G18Cs that had a metal slide was so fubar ... I have videos somewhere but somehow all the gas in the mag would discharge blowing the slide off XD

the gun is still jamming i took it all apart and nothing seems wrong but i got it from the asc armoury last year and its never worked on full auto but since the armoury is no more i have no idea what to do now

How well does semi work?

semi works fine
