Here in Edmonton Alberta, Canada, it is the rifle send to the gunsmith more then any other rifle for breakdowns.
The most frequent one is extractor breakage and malfunctioning bolt stop, meaning when you pull the bolt back she comes right out of the receiver.
Trigger is poor.
The bolt shroud is some sort of potmetal casting.
The A-Bolt is made for the guy that shoots may be one box/year.
It is NOT made for the person that shoots a lot.
Their accuracy out of the box is usually surprisingly good.
