WE Hi capa help

[Nbkelias]

Hi there everyone im just new the forum and just going to start going back to airsoft after a 10 year gap I got my guns out and gave them a good clean but ive been having problems with my hi capa when I fire the gun I only seem to get the first round unless I physiclly pull the slide back it feels and looks as if it kicks back enough when firing that it should load the next round so I think it maybe the feeder but unsure

Has anyone ever experienced similar problems

And could anyone recomend a

Piston / feeder / spring upgrade kit
