Help with Glock 17

RichCRX

Hey there,
New to all this and I'm having a bit of trouble with my KWA Glock 17.I recently got ultra gas for the gun as it is a GBB gun.However when I fill the mag up with gas i.e. leave it in for 5 seconds...and I fire about 2 bb's which the gun has the gas blow back effect but then it dies like there is no more gas in the mag and won't shoot anymore.I have even tried leaving the gas bottle on it longer than 5 seconds and still nothing...It fires about 2 bb's and stops.Anyone got any ideas?

are you turning the mag upside down and filling in with the gas can inverted above it
a 5 second fill should last approx 40/50 BBs

RichCRX

no im filling it vertical on it

I've done it both ways to check and basically it fires about 2 bb's and then It stops...I can sometimes see the gas out the front of the gun as the 2 bb's are fired...like the gas is leaking from the mag

Put the mag to your ear, can you hear any gas escaping from the filler valve on the mag? Do you have any silicone spray? give the valve a quick dart of silicone spray.

Gice it 10-15 secs filling to make sure its full.

i assume the slide is free when you pull it back by hand and snaps back freely under its own spring
removing the slide and spraying with silicone oil will help alot

I can sometimes hear gas coming out the valve and other times not.

The metal slider is running smoothly.Will get some silicone and try that.

Only use silicone oil
Do not use WD40 as it will rot the seals in the mag

give the mag a whacking of silicone and then leave it on the radiator to warm up. then gas it and see how its getting on. you shouldnt be able to hear any leaks from it then. if you still can then you'll have to strip down the magazine and grease the seals with silicone grease.

ya will only use silicone no need to worry:DThanks lads will update after a good siliconing:)
