KSC Glock 17 Issues
24 October, 2013, 22:42
Hello,
My KSC Glock 17 is having a few issues.
When I fire it sometimes it fires twice in quick succession, other times the slide returns 3/4 of the way back and becomes stuck usually after I push it forward and fire again it vents gas. If I've no BBs left in the mag and I replace the magazine and press the slide release nothing happens and the slide doesn't go forward as it should.
Any advice would fantastic, but if you would be so kind and use part numbers when talking about specific bits so I can refer to a diagram that would be ace. So far I've replaced both BBU #23 springs and given it a clean.
Cheers

Re: KSC Glock 17 Issues
Having looked at the recoil spring there does appear to be a few minor cracks on it so i think I'll replace that and see how it goes, what sort of damage would I be looking for on the rocket valve? also what would be the best way to test the seal with the router

Re: KSC Glock 17 Issues
thanks for looking ^^ i was asleep when i posted that reply ^^;
anyway
rocket valve problems can be
broken and or missing entirely. normaly hapens with plastic ones rarly metal fails but who knows its airsoft anything can happen.
or the spring for the valve iirc part25 can be misshaped.broken or stuck.
or
the cross retaing pin in there that holds the valve and its spring in place could have fallen out or slipped out on one side.
as for router sceal
this can be caused mostly by mag catch ware. the plastic catch warws down so mag moves down and doesnt sceal.
this is easy to test. pop the mag in and does it rattle or push upwards into the gun. tell tail signs there worn.
and if the mag is realy realy old the friction could have worn the router down aswell.

Re: KSC Glock 17 Issues
Checking the rocket valve, its metal and no bits appear to be missing. Replaced spring 25 and part 26 is pretty secure. The mags seem secure and no play at all, I would test itbut I've ran out of gas, typical! Looks like I'm off to PB tomorrow ¬_¬

Re: KSC Glock 17 Issues
hmm ok next thing to check out is the hammer and its sears on it. if there ok then next step is to see if the triggerbar part92 is ok.
when you pull the trigger fully with the slide off. does the other end of the bar easily slip/click under the sear? i guessing its like the 18 in that respect.

Re: KSC Glock 17 Issues
Actually the trigger bar does slip under the sear rather easily

Re: KSC Glock 17 Issues
If trigger bar slips off the sear then you can and down the nub on top of the trigger bar a bit, that's worths for me before.
If it's double tapping that suggests a broken sear though.
