Getting ready to order SSK

Going to order today, this is what I'm going to request. Any suggestions before I place?

1 in 8"
Medium weight finished at .750"
Threaded (not sure which threads)
Gas port in the pistol position
Adjustable gas block that will fit under the hand guard
Long Free Float tube (~14-15")

Hoping to acheive less that 1moa with 220gr sub and 125gr super.

What else do I need to know?

Thanks....
