I just purchased a used Norinco M305 from shooters choice in Waterloo. I went out in the woods to squeeze off a few rounds and nothing happened. I thought it was a misfire (quite a coincidence on a first shot of brand new ammo) but regardless I was safe and waited about a minute before ejecting the cartridge and locking the bolt. I looked at the round and at first it seemed there was no firing pin mark and I though wft? but then I looked harder and there was a faint indent not enough to ignite the primer. This says to me there is something wrong with the firing pin.

Am I wrong?

What can I do to remedy this?

If I need a new firing pin where do I get one from?
 
I would disassemble the bolt and examine the firing pin. You can find instructions on the net and even youtube videos. There might be something wrong with the firing pin, or it could be gummed up or jammed with brass particles. Mine once formed a brass ring around it.
 
the m305 bolt is difficult to disassemble because the ejector spring is longer than
a usgi one.remove bolt from gun and slide firing pin back and forth inside bolt.
If it's binding/sticky then it's grease/cosmoline in the bolt.push firing pin forward
and see if pin sticks out from bolt face a few millimeters.
 
There's no way we can guess with any certainty what is wrong. You will have to either take it to someone experienced, or if you are handy with mechanical things, take it apart and try to spot the problem. When you dry fire the gun, does it seem clear that the hammer is cocking, and then when you pull the trigger, that the hammer is dropping fully? You will need to follow the chain of events from cocking to dropping to striking the firing pin.

When you remove the bolt, even without disassembling the bolt, you can check to make sure the firing pin protudes from the bolt face.
 
Are you positive the bolt was fully closed?
Is the rifle well greased?
The built in safety feature that is supposed to help reduce out of battery fire, if working correctly, will cause exactly what you describe.
MANY new to this rifle "baby" the oprod, or ride the oprod to chamber a round. This can cause an almost closed bolt.

Take the bolt out, give it a few shakes. If you hear the firing pin moving as you shake it, this is good.

Take her out shooting. Load 1 round in the mag (always feed from the mag and never close the bolt with a round already in the chamber)
Pull back the oprod in a rear and downward motion and let it fly home.
Physically look at the bolt to ensure it's closed.
Squeeze trigger and If it fires, you should be good to go.
If not, back to the store I'd say ;)

I did hear the firing pin fall when I pulled the trigger it might be a matter of what was mentioned above about it being gummed up with brass or something. I will disassemble the bolt on the weekend and take some pics to show people.
 
check the gas shut off in on the gas system. its a flat head screw. if the slot is vertical then it is in the right position, if its not, turn it 90 degrees and try again.
 
If you plan on taking the bolt apart without a bolt dissassembly/reassembly tool, I suggest you do the job with your hands inside a clear garbage bag. This will help you catch any springs that want to fly off into the abyss. If cleaning the bolt while assembled, I find the best thing is a degreaser in a aerosol can with a straw nozzle.

Question: When you say the rounds dont eject, does this mean that the bolt is not moving to a rearward position, or does it mean the bolt is cycling but the round is not leaving the chamber? The first would lead me to suggest its a problem with your gas set up, while the second would suggest either an issue with the extractor or shortstroking.
 
The bolt isn't moving reward it's just staying in place. I don't know why it started working I took the bolt out but didn't disassemble it. Put the beast back together took it out and it shot fine some how bullseyed on the first shot from 50 yard (didn't think I was that good haha). I might be heading out again today I will check everything over again before I go out.
