I received my new TM Hi Capa 4.3 2 days ago and tried it out for 15 or so minutes and it appeared to be working fine. However, today it seems to have developed a few issues; feeding and slide locking back when empty.
When 'chambering' a BB/racking the slide manually, it feeds and shoots fine. The next shot however may not, and it will dry fire; requiring me to either rack the slide manually or keep dry firing until it feels like working again.
I have tested the loading nozzle by pulling the slide back slowly and holding the Hi Capa upside down, and each BB feeds fine.
In addition to this, when the magazine is empty the slide will sometimes not lock back. It works fine when I pull it back but if I fire the last BB in the mag it doesn't always work.
After disassembling and reassembling (but not having applied any more lube) the Hi Capa itself seems fine, although upon wiping the little square opening on the loading nozzle with a bit of tissue, there was some dark residue.
One thing I have noticed is that if I fire shoot slowly (1 BB/second) it doesn't seem to have as many issues as when I shoot rapidly.
Could it be something to do with the Gas cooling down to the point where it causes these issues?
I am using Abbey Predator Gun Gas 144a.
This is my first Gas airsoft gun.
Thanks for the help.
