Noob here: charging handle


After pulling down my m4 blaster the charging handle does not work. Any advice would be welcome

what were you expecting it to do? most times its either a mag prime or just for looks.

All mine do is open that door as in picture

I’m guessing you mean the door/dust cover won’t stay closed?

No i mean the slide won’t pull back any more. Its catching on something

Maybe pull the 2 pins and lift the top half of reciever up a little bit and see if that loosens it

Nah hasn’t worked yet and I have fiddled with it a bit. Ill just keep at it

I have never had that happen so not sure what it would be
