It's a blued finish, so I would assume chromoly, has the 3 lug bolt, 26" fluted barrel, bell & Carlson fiberglass stock with alum bedding block, factory picatinny rail, etc. feel free to shoot me a PM and I can get you my phone # for more specifics. As far as it shooting under sub-MOA, that shouldn't be a problem. sako has a 3-shot sub MOA guarantee, and by all the reviews it more than delivers on that. Of course there is ammo that it just "won't like", but my buddies rifle (A7 long range 7mmRM), my sako, and my Tikkas all are incredibly accurate. Like I said shoot me a PM and I can try to help with some more specifics, also there is a decent amount of info on the internet to help with your research and with others opinions.
