Let me start with that I'm new to NV. I know little!

Looking at a clip on NV, seems that I could use it on any of my rifles, and use the rifle w/o it attached. Am I understanding this wrong?

So I'm thinking thais: https://www.atncorp.com/nightvision-daynight-atnps28-3

Are there other options? Please, give me some ideas and options!

Purpose is ultimately hog hunting. Also, yokes and the random critter in the back yard. My main rifle of focus is sr25 w/ accupower 1-8.

Are there better options or systems that I should consider?
I could go dedicated NV rifle, I have options.

Thank you.
