I picked up an older 110 E-H in .308 and am having a 24" Shilen barrel made for it that is a little heavier than the stock barrel of 20". I am wanting to put a new stock on it as well. Are there any stocks out there that I can drop this into or will I have to fit it?

Also, how do I tell if it is a long action or short action. It has a hidden magazine.
