Glass suggestions on a budget

[MF'nLeadFarmer]

Hey all I'm brand new to the AR world as well as to the 6.5G. I'm looking at building an AR lower and putting a J&T Distributing 24" bull barrel upper. I primarily want to shoot from a bench for fun/ accuracy. I will eventually but with this rifle also. I'm looking at optics and have $300-$400 to spend. I was looking at:

Leupold VX II 3x9 40

Leupold Mark AR 3x9 40

I want to stay with Leupold as I live here in Oregon and take comfort in knowing they're near if I need them. Any other suggestions?

Will the Mark AR's 5.56 specific settings even work with the 6.5? Thank you.
