I have a couple of questions. I have torn it apart and cleaned it so that is not the problem. I need to know how much protrusion you have on the firing pin on the 204. I just bought one and am not happy with it at all. Out of the three times I pulled the trigger to fire it it only hit the primer hard enough to fire the first time. I called NEF and they said the protrusion should be .035. Mine is at .041 and my 223 is at .051, so I dont think the .035 is right. I am sure that is where the problem is. They say they have not heard of this problem before, I know that is a lie since I had the same problem with my 17 hmr and sent it back. They ground on the action to make the hammer go further forward so the transfer bar pushed the firing pin out further. Looks like crap. They could have ground the hammer instead, so I would rather not send it to them.
Next it does not latch without slamming it but I have found on here how to fix that.
This one extracts the shell instead of ejecting it like my 223. Should it extract or eject.
I have had the same problem with 2 out of 3 new rifles I have bought from them.
Thanks for any help you can give.
