That Wraith will be overkill and costs at least twice the guns' worth. I and many others have killed hundreds of rats with the simple red light suggested before. It's an inexpensive way to see if your "night pesting" is what you think it is. But if your set on the Wraith the link above gets you the adapter you need or, put you on the right track for such adapters. Good luck!
As much as I like the Wraith Mini, it isn't a great fit for the Stormrider. You'd be better off with a red light as L. Leon mentions.
If you use an adapter, you just add more room for potential slop, and you might have to re-zero your scope every time you mount it. If you have a red light on your gun, you can maintain your zero from your iron sights.
Wraith Mini has a 2-2.5” eye relief. Basically length of rubber eye cup. I mounted Wraith mini on FX compact with factory plastic stock with LOP of 14”. I changed the FX to adjustable stock to lessen the LOP. Shorter LOP worked much better.
