    sticky pin gets lubed and worked until it smooths out

    would need pics to help with the catch

    I think I found issue but will probably have to take to gunsmith to resolve I lubed up the pins played with them until they were smooth put the upper back on was still sticky lubed the holes on the upper where the pins attach didn't make a difference so I swapped my upper with my wife's upper and no issue I'm going to try and take a little of the finish off with sandpaper or Emory cloth if this doesn't work I will need to take it to a gunsmith to remove a little metal
