Would you stop with this nonsense? It's not true no matter how many times you say it. The factory stock is fine. Better than the factory stocks on most other $700 rifles. I am happy that Tikka doesn't spend half of the T3x's budget on a mid-level stock. The point is, a $700 Tikka is better than any other $700 rifle and most $1k+ rifles.
Put a $600 stock on it and you're done, in for $1300 on a rifle that I would take over any Bergara, Christensen, Fierce, etc. the same can't be said for a Ruger American, Savage, entry level Bergara, etc. they are mediocre at best no matter what fancy stock you put them in.
That's why I super glad they offer the T3 with an inexpensive (but still perfectly usable) stock. Very high quality action, barrel, and trigger ready to drop into MY choice of stock. Better that than what most other manufacturers do (lower quality action, barrel, trigger to free up room in the budget for a more expensive stock like the Roughtech that still doesn't end up being quite what I want. But that doesn't make replacement mandatory (and definitely doesn't make a different $700 rifle a better gun).
