I was looking at the Tikka website the other day and noticed the new T3x model, which addresses many of the deficiencies of the T3. Tikka T3x
They've opened up the ejection port, added a metal bolt shroud, and attachment points for a rail on top.
The synthetic stock has been re-worked, but that is a moot point with me as I greatly prefer walnut.
Something to look forward to. I haven't seen any for sale yet.
