You do realize that Tikka puts the same action and barrel in all "grades" of their T3X line, right? The only thing that really differs between a $1.4K Tikka T3X CTR (Compact Tactical Rifle) a $2.4K T3X UPR (Ultimate Precision Rifle), and a $3K T3X Tac A1 (Tactical) is the stock/chassis. That's it, that's all that sets the 3 different "grades" of Tikka apart. A CTR Barrelled-Action in a chassis will shoot just as well as the Tac A1, because they are the SAME rifle - just in different grades of stock/chassis. Barrels are available in 30" and 34" lengths. All Tikka Barrels are warrantied to group 3 rounds of match ammo under 1 MOA.
So, if you are looking for a Tikka tack-driver you need look no further than the $1400 CTR, throw away the garbage plastic stock, and plop it into the MDT (or KRG, or.... ) chassis of your choice for the same or less money than you would spend on the Tac A1. Do it the way that I suggest, and You get the exact same rifle, but a better, more personalized choice of stock or chassis. The T3 Tac A1 is the "easy" route, as everything is done for you. However, you are paying $1500 for an inferior chassis design compared to just about anything that MDT or KRG produces. At the "expense" of loosening and re-torquing 2 Action Screws, you can have the chassis that YOU want.
Just a suggestion, that you are free to ponder or reject as you see fit. But why settle for a chassis that needs tools to adjust the Length Of Pull (LOP) when you can get a tool-less solution from MDT or KRG for probably less money overall? It's a win-win to buy a CTR and stick it in another brand of stock/chassis. The Tac A1 is just a CTR tarted up with a $1500 chassis that isn't particularly well-featured for the money. You can honestly do much better spending that $1.5K on an MDT or KRG stock or chassis system.
