The Vortex Crossfire II AO 4-16x50 mm Riflescope does not have parallax adjustment. But has a parallax setting of 25 yards to infinity.
On this rifle, a pair of the Pro-Series 30mm mediums will offer minimum clearance. This rifle should run a picatinny-ring compatible rail, otherwise!
The Vortex Crossfire II AO 4-16x50mm uses a 50mm objective lens and would require you to use High Height 30mm scope rings in order to allow for clearance of the lens over the barrel. I would recommend using the Vortex Tactical 30mm Rifle Scope Rings which can be found by using the link below. However, you can use any High Height 30mm scope rings you desire.

If mounted on a 1-piece picatinny rail, you could run the Pro-Series 30mm rings without issue - PN# PR30-M!
This Vortex Crossfire II AO 4-16x50mm 30mm Tube Second Focal Plane Rifle Scope would be good option for your Ruger American Ranch. It uses the Dead-Hold BDC reticle which allows you to use the holdover and windage hashmarks to make more accurate shots. It is compatible with multiple calibers as well.
Yes, the Vortex Crossfire II AO 4-16x50mm Rifle Scope would work well on a 6.5 Creedmoor.
