So I am looking to get the wife and I an Avenger in .22 cal. and a Sightmark Wraith HD so she can obliterate the nasty rat vermin in the back yard. We already have an RWS Model 34 in synthetic stock that shoots OK but it's a springer. She wants to be able to kill these things at night when they are most active so that is why I mentioned the Wraith HD scope. Anyone have any advice? I see an Avenger that is quite reasonable on the BST but I still can't use the PM feature yet which is really frustrating.
