I definately don't mind answering questions.
That's what the forums are for.
I was just poking at your eagerness.
I forgot to mention, the rails are bolt on.
So to sumarize:
-Super Varmint is basically the same as the Varmint but with the adjustable stock and picatinny rail found on the Tactical.
-The rail is screwed on and the reciever is still milled for the regular Tikka rings.
-The Super Varmint has the standard blued or stainless finish vs the parkerized finish of the Tactical and the Super Varmint's muzzle isn't threaded like the Tactical.
Tikkas are great guns. I have a T3 Lite in 308 and wouldn't trade it for any Remington 700...
Personally if I were looking at the T3 Super Varmint or Varmint I'd probably spend the extra $50-60 and get the Super.
The regular T3 rings work okay, but a picatinny rail would be much much better. Since a one piece mount for a T3 would cost $40-50 then you might as well get the picatinny and adjustable stock for a couple more bucks.
You'll be happy if you end up buying a T3.
