I have read many good things about the Tikkas, but never owned one. Ran across a used one at a great price (includes a Leupold Mark 4 3.5-10x M1 Mil-Dot scope), and need some advice. Its serial number dates it to 2007 - and I don't know the round count. My question is this - what should I be looking for on a used Tikka for signs of wear/breakage/whatever? What would be reasons to not buy it? Thanks for any and all help.
