I think the eyepiece won't give you a stand-alone scope. It will only enable you to use it as a monocle.
I think you must buy the eyepiece attachment AGM Global Vision Rattler-C V2 Eyepiece 6328XER21
To the best of my knowledge, it can not. From what I have read in my research, the eye relief is not compatible with being used as a stand-alone optic. I also don't believe this model has a reticle. Hope this helps.
