Winchester 1200 jamming

[pintailslammer]

I got a Winchester model 1200 and have a problem with it

I totally dis-assembled the trigger assembly and cleaned it and re-assembled as it was when it was taken apart.
Here is where it jams.
The gun I bought was missing the firing pin assembly,breech bolt,slide arm bridge,etc and a ejector slide,
I bought these parts on the weekend at the Lloyd gun show. Bruce sold me the pieces and assembled it to the point all I had to do was tighten the screw when I got home,
I assembled it all together but when I slide the action back it jams and I have to remove the trigger assembly to get it to move forward, I talked to a fiend and grabbed his 1200 trigger assembly just in case I screwed up some where but it still jams.
Im confused as to what to do now so if you have any suggestions feel free to drop them

Thanks

Try your buddies trigger assembly in your gun? You could have a bent receiver?

If I remember they made a few different slide arm bridges . May have wrong one ?
Make sure carrier dog and spring are in correctly

Is the bolt opening out of the barrel extension? Winchester had trouble and a fix for this in the 70s . Action would start to open then stays locked in the barrel . Does it work with barrel off

Maybe disconnect spring not properly installed or disconnect it self not installed properly.

It's one of those that a I would need to see to fix

I had Win 1200 as a kid that after a year the magazine catch that holds the next 2 rounds in started to fail letting both shells back every time it was fired.Sent it back to the factory and it was doing it again in no time flat.Other 1200 owners have had same problems.This may not be your issue but may surface.

So I took it to a friend who works on these and he had told me
that the part I bought on the weekend from the gun show in Lloyd
are wrong. The breech bold slide is from a 1400 not a 1200 like I asked
for,The trigger group that was in the gun is from a 2200 but should be there same as a 1200(i think)

He's going to check tomorrow to try and get the proper piece in it.

If anyone has Bruce Tauber cell number Id sure like it, or if your on here
Bruce shoot me a pm
