Hello NV users. I want to put thermal on either a Ruger 10/22, or wife's S&W MP15-22, our problems are barn rats and foxes, occasional, close quarter coyote. Distances are anywhere from 5-10yd out to 100yd max, most shots being the closer. What do I need? I know NUTH'n about night vision, except that it beats a Tac light! Any help or suggestions would be appreciated, Thanks.
