Id go with the Aimpoint Micro T-2. It’s compact and tough, almost like it could survive a drop from the top of a mountain. It’s also fully sealed and has nitrogen purging, which means you won’t have to worry about any fog ruining your view, even in those really swampy conditions. Trust me, I’ve taken it out during early morning hunts and on rainy range days, and it has performed like a champ without any issues.
