HP PPSh-41 not shooting

[timberwolf61]

Alright, I'm new to airsoft so I need some help...I got this gun a few weeks ago and it wont fire. If you're familiar with this gun there was a problem with the drum mag feeding and there was a video online of how to fix it, and I did that. The battery is fully charged, I adjusted the hop up, cleaned/oiled the barrel and checked to make sure the nozzel wasn't sticking out and it still wont work. When I pull the trigger it will only dry fire. It will occasionally shoot 2 bbs at once then shoot a few more every couple of shots but thats it. It's not the drum because the bbs will go up into the receiver but just sit there. Does anyone have any idea whats wrong with it?

1) Please don't oil the barrel, clean it out with windex and make sure it's 100% dry
2) Did you silicone lube the mag?
3) If you look into the feed path, can you see the air nozzle moving back and forth?
4) At any time have you taken the gun apart?
5) What kind of ammo are you using?

I already did dry it. I just oiled it clean it out then I dried it out afterwards.
I lubed one part because it was the only metal part, I wasn't sure if the stuff I was using was safe on plastic or not.
When I lift the back part up to see if it is moving back and forth sometimes it does and sometimes it doesn't. Sometimes it doesn't even blank fire when it's opened up.
No, I haven't taken the gun apart.
I'm using crosman bbs.

You problem right there.

These should only be used in 40mm nades, claymores and the cheap springers they sell.

Get some good BB, such as the BBBastards and you should not have any problem.

Use KSC or other such name brand BB's, with a weight of .20g or .25g
Using low quality BB's WILL break your gun internally
