Hi. I know just a little on older AI and I have been interested in buying one just for owning a piece of history. There is an AI on Gunbroker that has caught my eye. I will post the link at the end of the thread. It has the rounded end on the bolt assembly with a non folding green stock. Is there a way to determine the year of this model? My AI has the year of manufacture prior to serial number. I couldn’t make it out on my phone. What are your thoughts on this rifle? Appreciate any input.
