I won a little money in a sports pool and was thinking about getting into the thermal game with my winnings. I'd like to maybe be able to shoot varmits, yotes with it. Most of my shots would be 150 or less. I already own a DPMS Ar15 in .223 but am new to the whole thermal and suppression stuff. Would this gun be a good setup to get started and keep my costs down. What exactly do I need and what can I expect to spend to get a good quality setup?
