Hey all;

Looking for advice here: I royally messed up an M305 trigger group. after assembling, I cocked the action, and it stuck to the rear. Gave 'er a tap on the op rod to push her forward, and everything seemed ok. Did a few more cycles of the action, and things were stiff - so I removed the trigger group again - it was flippin TIGHT getting out (way tighter than normal).

Anyways, now that I see it, the trigger is stuck to the rear, and the trigger pin is partway out and wedged in there. The hammer is fully cocked. I am able to get the trigger pin in and out partway, but it won't go back in all the way.

Any advice?

Any Canadian M14 gunsmith recommendations (in Canada) that can mitigate this sort of damage? I figure while it's out, if I'm sending it off for repair, I might want to look at getting a trigger job done on it...
 
I can't help you directly as I'm no expert: Go to Youtube and search for Norinco M 14 trigger. There are a few videos of how to take them apart and re-assemble them. It could help you understand your situation better.
 
Thanks for that link! It definitely helps me out seeing what's going on there, but for me the problem I have diverges at 0:52 in the video - where he eases the hammer spring. With my hammer stuck to the rear, everything is under serious tension from that spring. Can't move the trigger (it's stuck rear, so the hammer stays locked back), and I can't align the holes for the pin, etc. It's quite confounding!
 
Ok, I have run into this a few times, I hope that you are familiar with typical M1/M14 trigger disassembly. What you need to do is push the trigger/disconnector assembly forward with your thumb or fingers, while you reinstall the trigger pin. It isn't that easy to do, and if you have weak thumbs or arthritis, it can be very difficult. If you can de-#### the hammer it will be much easier, but that may be difficult. Once you have the trigger pin reinstalled and the trigger assembly is working normally, then you can disassemble the trigger assembly as normal. The important thing to check is the stock, it should fit snuggly against the trigger housing and prevent any pins from walking out in use.
 
As I don't have a third hand (well I have a tool called such for bike repairs, but not relevant here), placing the trigger group gently in a vise will allow you to compress the spring and manipulate the trigger to the point where you can puch the pin in with just finger pressure.

Now that you mention it, that is EXACTLY what happened. I was working on two at once and I think I put the wrong trigger group in the wrong stock.

Stupid, stupid, stupid. :/

It's after 1 am where I'm at - I think I'm going to try to fix this tomorrow after work.

Thanks for the advice all!
 
Y'all rock!

Ok - couldn't sleep, and got back into it. Thanks to all your advice (and a particular thanks to 604Hobo) I got 'er back together!
