Personally I'd wait until you've tried the scope on ordinary mounts first - the T2 turret might only be Marked up for 1/2 MOA but may allow adjustment to 1/4 MOA.
If it really is 1/2 MOA and you go down the adjustable mount route - Don't go for b-squares. Its not possible to adjust elevation on the b-squares to 1/4 MOA accuracy. Getting the windage right would also be more luck than judgement too.
I can't comment on the Sportsmatch adjustables as I've never used them.
