Just wanted to add to this thread. if the rifle is a new in the box rifle 9 times out of ten it is the a-bolt II. if it is used it could be the older model a-bolt. also wanted to point out that while there are better choices for a custom rifle, the a-bolt II will also work if you are looking for something other than a remmington or a winchester. i have 2 a-bolts II rifles that have been fully customized and the smith i use said he had zero problems working on either. just food for thought...
