Yes. The Scalarworks QD Scope Mount is 1.93" to center of the optic making it ideal for the AR15 platform and night vision use. Scalarworks does make a mount that is 1.57" center height which may be a better option if you are not using night vision.
While this Scalarworks QD Scope Mount will work with your setup, it may sit a little too high up making it uncomfortable to use on a Ruger American. With a 50mm objective lens I'd recommend using high height rings or AR15 height mounts. Aero Precision makes a nice mount that would work well with your setup found using the following link:
