MKII bolt/trigger problem

Took one of my MKII out today that I have never shot (bought used last year) and I noticed when I held the trigger in after a shot the bolt would not go forward all the way until I let off the trigger.

It does this even when unloaded with no magazine in the gun. If I hold the bolt ears and move back and forward with trigger pulled I can feel the bolt dragging on something.

I removed frame from reciever and I cant see any drag marks on bottom of bolt BUT the disconnector assembly seems to catch on something beside the hammer.

Hope I exsplained well enough what it is doing, any ideas?

No better time to upgrade to some volquartsen parts right

Thanks for any an all help, Mike

Sounds like the disconnector my be hanging up and stopping the bolt. There is a spring and plunger in the trigger that gives it upward tension. I am thinking maybe this spring and plunger may be rusted or gunked up with grease or dried oil or (God forbid) WD40 residue from a previous owner.

The disconector I belive is the problem for sure, once apart I can feel it hanging up on something. It all really clean but could be a bur catching it or like you said the spring in the plunger. Going to strip it all the way down today. Update ya as I go.
